EU demand leads to Talga expanding battery plant

Posted By Graphene Council, Friday, June 26, 2020
Overwhelming European demand sees Australia’s battery anode company Talga Resources plan for expanded output at its new Swedish battery anode factory.

Expressions of interest received for Talga’s lithium-ion battery anode products exceed 300% of planned annual capacity of the Vittangi Anode Project, the company says.

Talnode products are now in 36 active commercial engagements covering the majority of planned European li-ion battery manufacturers and six major global automotive OEMs.

Talga says it’s expanding the scale of the Niska scoping study for the Vittangi Project to review larger anode production options as a result of this significant interest.

Li-ion battery megafactories are set to require more than 2.5 million tonnes per annum (tpa) active anode material by 2029, up from about 450,000 tpa anode production today, with Europe the fastest growing market.

That’s because worldwide li-ion battery demand continues to rapidly increase, with global battery manufacturing capacity set to exceed 2.5 tera-Watt hours (TWh) per annum by 2029 across 142 battery plants.

“Our engagement with European battery companies and automotive OEMs has grown rapidly, with customers attracted by the potential of locally produced anode at competitive costs and with world-leading sustainability,” Talga managing director Mark Thompson says.

”As we progress Talnode-C through commercial qualification stages with customers it is pleasing to note that interest now greatly exceeds our original planned production, and that the need to review expansion options has arisen this early.”

The increased interest means the company is targeting completion of the Niska scoping study in Q3 2020.

While COVID-19 has severely impacted EV sales in the short term, Bloomberg New Energy Finance data shows EV sales hold up better than internal combustion engine (ICE) vehicles due to new (lower cost) models and supportive government policies.

In the quarters prior to the COVID-19 outbreak, EV sales as a percentage of total passenger vehicles rose rapidly in the EU, with Germany and France recording increases of 100% during the period.

Numerous countries across Europe have implemented some form of financial incentives towards customer uptake of EVs, and post COVID-19 these have increased markedly in some countries.

Talga is entering the European market at a time when 100% of anode supply is still sourced from Asia. The company’s marketing team reports that, post COVID-19, localisation is becoming an increasingly significant factor influencing customer’s purchasing decisions.

Talga Looks to Expand Battery Anode Capacity

Posted By Graphene Council, Wednesday, June 24, 2020
Battery  anode  company Talga  Resources  Ltd is  pleased  to provide an update on the development of the Vittangi Anode Project in northern Sweden.   As part of this  on-going  development  the  Company  is  engaging  directly  with  lithium-ion  (“Li-ion”)  battery manufacturers towards purchase agreements for its planned anode production.

Commercial   samples   of   Talnode-C,   and   in   some   cases   Talnode-Si,   are   progressing   through confidential  qualification  processes  under  36  active  customer  engagements.  These  include  the majority of announced Li-ion battery manufacturers in Europe (see Figure 1) and six of the world’s major automotive OEMs.

Expressions of Interest received by engaged parties for supply of Talnode-C in 2023 exceeds three times the annual production capacity proposed in the Company’s Pre-feasibility Study1. As a result of this  interest,  Talga  is  expanding  the  Niska  Scoping  Study  underway  to  evaluate  significantly  larger anode production options for the overall Vittangi Project.

Commenting on the Company’s progress, Talga Managing Director Mark Thompson said: “Our engagement  with  European  battery  companies  and  automotive  OEMs  has  grown  rapidly,  with customers attracted by the potential of locally produced anode at competitive costs and with world- leading  sustainability.     As  we  progress  Talnode-C  through  commercial  qualification  stages  with customers it is pleasing to note that interest now greatly exceeds our original planned production, and that the need to review expansion options has arisen this early.”

Planning for expansion of anode production – Niska scoping study

Based on the strong interest from industry and the anticipated permitting timeframes in Sweden, the  Company  has  decided  to  expand  the  Niska  scoping  study  of  the  Vittangi  Project  to  review significantly  larger  anode  production  options.  The  outcomes  will  be  in  addition  to  the  current Nunasvaara South PFS production plan of 19,000 tpa*.

This  scoping  study  is  underway  on Talga’s  three  Vittangi  graphite  resources  not  currently  in  the PFS; Nunasvaara North, Niska South and Niska North (“Niska Scoping Study”), all located within approximately  2.5km  kilometres  north  of  Nunasvaara  South  (see  Figure  2).    Collectively  these JORC  resources  total  6.5  million  tonnes  at  26.8%Cg  (see  Table  1),  including  a  higher  grade resource domain at Nunasvaara North of 900,000 tonnes at 33.0%Cg (see Table 2).

A  mining  study  supporting  the  larger  scale  project  has  been  completed,  and  metallurgical  and battery  product  testwork  on  composite  samples  is  underway.  Due  to  the  significant  increase  in scale, the Company is targeting completion of the Niska Scoping Study in Q3 2020.

Li-ion anode market growth

Worldwide Li-ion battery demand continues to rapidly increase, with global battery manufacturing capacity set to exceed 2.5 tera-watt hours (TWh) per annum by 2029 across 142 battery plants. This will require >2,500,000 tpa of graphite anode, up from ~450,000 tpa anode production today. Europe  is  the  world’s  fastest  growing  region  for  Li-ion  battery  manufacturing  and  will  require
500,000 tpa of new graphite anode supply by 2029.2

While the COVID-19 outbreak in 2020 has severely impacted electric vehicle (“EV”) sales in the short  term,  Bloomberg  New  Energy  Finance  data3  shows  EV  sales  hold  up  better  than  internal combustion engine vehicles due to new (lower cost) models and supportive government policies.

In the quarters prior to the COVID-19 outbreak EV sales as % of total passenger vehicles rose rapidly  in  the  EU,  with  Germany  and  France  recording  increases  of  100%  during  the  period4. Numerous countries across Europe have implemented some form of financial incentives towards customer uptake of EVs, and post COVID-19 these have increased markedly in some countries5.

Vittangi Project Supported by National Interest Demarcation

Posted By Graphene Council, Thursday, June 18, 2020
Battery anode and graphene additives company Talga Resources Ltd is pleased to advise of positive developments at its 100% owned Vittangi graphite project in northern Sweden (“Vittangi”).

A recent decision by the Swedish Geological Survey (“SGU”) completed the demarcation of Vittangi as a mineral deposit of national interest1. This designation adds support to consider the exploitation of Vittangi as a mineral deposit when government authorities review development plans and any potential competing land uses.

Under the Swedish Environmental Code, deposits of valuable substances or materials can be defined as being of national interest, meaning municipalities and central government agencies may not authorise activities that might prevent or significantly hinder exploitation of the mineral deposit. The national interest area covers the entirety of Talga’s currently defined Vittangi graphite resources (see Table 1 below), and undrilled extensional deposits, as detailed in Figure 1.

The SGU noted the Vittangi graphite deposit's significance to the country's supply capacity and its special material properties and concluded the deposit constitutes a unique natural asset of valuable substances or materials.

Further, they consider locally produced graphite could help strengthen the competitiveness of the Swedish battery manufacturing industry and that, as the known highest grade graphite deposit in the world, Vittangi could “meet a great need not only within Sweden but internationally”.
The decision2 takes note of the European Commission’s listing of graphite as a critical raw material and their warning that a lack of access to such critical commodities could slow the development of fossil-free energy sources.

Commenting on SGU’s decision, Talga Managing Director Mark Thompson said: "We welcome SGU’s decision as a positive and timely development following Talga’s recent lodgement of the Vittangi Graphite Project mining permit applications, towards becoming Europe’s first vertically integrated producer of Li-ion battery active anode material."

SGU Decision Background
In preparing the demarcation SGU obtained extensive information on the Vittangi Graphite Project including details relating to its geology and material properties. The demarcation defines the boundaries of the original declaration of Nunasvaara as a deposit of national interest which contained only a centre co-ordinate. Results from Talga’s extensive exploration work were made available during the investigation and SGU carried out their own detailed electromagnetic survey to assist in the demarcation, which covers approximately 20km strike of graphite mineralisation.

Competent Persons Statement
The Nunasvaara Mineral Resource estimate was first reported in the Company’s announcement dated 27 April 2017 titled ‘Talga Substantially Increases Flagship Graphite Resource Size, Grade and Status’. The Company confirms that it is not aware of any new information or data that materially affects the information included in the previous market announcement and that all material assumptions and technical parameters underpinning the Resource estimate in the previous market announcement continue to apply and have not materially changed.

The Niska Mineral Resource estimate was first reported in the Company’s announcement dated 15 October 2019 titled ‘Talga boosts Swedish graphite project with maiden Niska resource’. The Company confirms that it is not aware of any new information or data that materially affects the information included in the previous market announcement and that all material assumptions and technical parameters underpinning the Resource estimate in the previous market announcement continue to apply and have not materially changed.

Battery anode agreement with Farasis Energy

Posted By Graphene Council, Wednesday, May 27, 2020

Australian battery anode provider Talga Resources Ltd is pleased to advise the Company has entered an agreement with Farasis Energy Europe GmbH (“Farasis”), a subsidiary of Farasis Energy Inc, one of the world’s leading manufacturers of lithium-ion batteries.

Talga is building a European anode production facility for lithium-ion batteries using the Company’s proprietary material technologies, wholly owned Swedish carbon source and 100% electricity from renewable energy sources. As part of the agreement between Talga and Farasis (“Agreement”), Talga will supply coated (‘active’) anode products for evaluation in Farasis batteries and assessment of potential business development opportunities, primarily in Europe.

Talga Managing Director, Mr Mark Thompson: “Following successful initial tests, we are very pleased to continue this progress in collaboration with the experienced Farasis team. Talga is making substantial progress in commercialising its European lithium-ion battery anode products, and demand is growing rapidly, particularly in the EV market. We look forward to working together with Farasis to advance our anode materials for their innovative energy storage solutions.”

Anode Market Background and Agreement Details
Talga is a developing lithium-ion battery anode producer in Sweden, utilising vertical integration and wholly owned technology to supply cost competitive and high-quality anode to European battery markets. The Company’s operations in northern Sweden use fossil free hydroelectricity, enabling Talga’s position as a low-emission leader in anode production and a secure local partner for the emerging European battery supply chain.

Europe is undergoing unprecedented growth in the demand for lithium-ion batteries, driven by the move to electric vehicles and renewable energy storage. This creates new demand for sustainable and locally sourced battery anode materials, such as Talga’s. In addition, global EV battery demand is forecast to grow 14-fold by 2030, which would require approximately 1.7 million tonnes of anode material per annum1.

Under the non-binding Agreement Talga agrees to supply Farasis with lithium-ion battery anodes in quantities as mutually agreed and required, with no contractually obligated minimum quantity, for evaluation and business development purposes. The Agreement is valid until 2024 and either party can choose to withdraw at any time via standard termination clauses, not constituting binding commercial terms. All of Talga’s intellectual property rights remain unaffected by the Agreement

The Company is unable to quantify the economic benefits to Talga arising from the Agreement at this stage. Further terms, including quantity and pricing, are subject to negotiations throughout evaluation and development, and in the event commercially binding contracts are entered into Talga will inform the market. However, Talga recognises Farasis commercial relationships, particularly with European automotive manufacturers2, to be well aligned with its developing Swedish anode business.

Talga in Innovate UK Electric Drive Project for Bentley Motors E-Axle

Posted By Graphene Council, Wednesday, May 13, 2020
Battery anode and graphene additives provider Talga Resources Ltd is pleased to announce it has been approved for Innovate UK co-funding to support development of an e-axle designed for Bentley Motors.

The OCTOPUS project aims to deliver the ultimate single unit e-axle solution designed specifically to meet Bentley Motors performance specifications via optimised motor and power electronics technology and materials. The project is funded under the Office for Low Emission Vehicles’ and Innovate UK’s “IDP15: The Road to Zero Emission Vehicles” competition.

Under the project Talga will develop and provide graphene materials for the high performance electric motor windings to deliver an aluminium-based solution aimed at outperforming, and ultimately replacing, the copper windings currently used.

The improved motor windings form part of the project’s aim of developing next generation lightweight high performance component systems that integrate the latest advanced materials and manufacturing techniques. The components are to be tested at sub-system and system level for an integration route into future e-axle designs.

Talga Managing Director, Mark Thompson: “We are delighted to engage in jointly developing Bentley Motors’ e-axle concept with our consortium partners and are honoured to have earned Innovate UK’s continued support.

The successful use of Talga graphene material to lend aluminium the properties required to outperform copper in electric motors would be a big advancement. For automotive manufacturers this could reduce vehicle weight and increase performance, safety and driving range while retaining sustainability and economics. Lightweight and high performance automotive components perfectly complement our Li-ion battery anode products, and the advancement could pave the way for opportunities to replace copper wire in many large-scale applications globally.”

Project and Funding Details
The OCTOPUS project funding extends to completion at end of 2022 and during this time Talga will retain current and arising intellectual property in its field. The Company can choose to withdraw from the project at any time and standard termination clauses typical of consortium project contracts apply.

Innovate UK has approved funding to the value of ~£3.6 million for the OCTOPUS project. Talga is eligible for ~£224,000 of this project funding, representing approximately 70% of Talga’s total contribution, to be provided in quarterly instalments over the funding period.

At this stage the Company cannot quantify the economic benefits to Talga from participating in the project. However the relationship with consortium partners and commercial potential of the arising products is well aligned with Talga's growing advanced materials and technologies for applications in zero emission vehicles.

Subsequent to the quarter, Talga announced its participation in the Innovate UK co-funded “OCTOPUS” project, aiming to deliver the ultimate single unit e-axle solution designed specifically to meet Bentley Motors performance specifications (ASX:TLG 27 April 2020).

Under the project Talga will develop and provide graphene materials for the high performance electric motor windings to deliver an aluminium-based solution aimed at outperforming, and ultimately replacing, the copper windings currently used. For automotive manufacturers this could reduce vehicle weight and increase performance, safety and driving range while retaining sustainability and economics.

The improved motor windings form part of the project’s aim of developing next generation lightweight high performance component systems that integrate the latest advanced materials and manufacturing techniques. The components are to be tested at sub-system and system level for an integration route into future e-axle designs.

Lightweight and high performance automotive components complement Talga’s range of Li-ion battery anode products, and success in this program would open opportunities to replace copper wire in many large-scale applications globally.

Commercial-scale ship coating trials push demand for Talcoat® samples

In the previous quarter, Talga released details of a Talcoat® product, a graphene additive for maritime primer coatings, applied on two 33,000 tonne ocean going vessels at sea under large-scale trials (ASX:TLG 4 November 2019 and ASX:TLG 17 December 2019).

Subsequent to the publication of the trials additional parties across several sectors of the global coating industry have engaged with Talga and received Talcoat product samples. These are now undergoing testing by manufacturers and applicators, varying in size and jurisdiction, with positive initial test results.

Negotiations towards purchase agreements are underway with some parties and details will be released as and when any definitive commercial agreements are reached.

MINERAL PROJECT DEVELOPMENT AND EXPLORATION

Stage 1 Vittangi mining operation receives environmental approval

Environmental approval for Stage 1 mining operations at Talga’s 100% owned Vittangi Graphite Project in northern Sweden was received during the period under review (ASX:TLG 3 March 2020).

The trial mine environmental permit was issued by the Environmental Review Committee within the Norrbotten County Administration Board and is valid for three years.

The permit allows for the extraction of up to 25,000 tonnes of graphite ore for planned processing into concentrate and refining at Talga’s downstream anode refinery to produce Talnode®-C, the Company’s flagship Li-ion battery anode product developed to provide a sustainable and cost competitive choice for battery manufacturers.

The permitting process included comprehensive test work and studies to minimise the environmental footprint of the operation and upon conclusion of Stage 1 mining the site will be rehabilitated using the successful measures from the Company’s 2015-2016 trial mining campaign.

Preparations for site works and contractor selection is underway with operation planning to commence following completion of further statutory compliance, Stage 1 refinery permitting and financing activities.

Environmental and statutory permit applications for Stage 2 mining and concentration operations, with a processing capacity of 100,000 tonnes per annum of graphite ore, are nearly complete but now expected to be submitted in Q2 2020.

In full-scale production the graphite concentrate will feed Talga’s planned downstream refinery in the coastal city of Luleå, 250km to the south, to produce 19,000 tonnes per annum of Talnode-C as per the design parameters detailed in Talga’s May 2019 Pre-Feasibility Study (ASX:TLG 23 May 2019).

Tenement Interests

As required by ASX listing rule 5.3.3, refer to Appendix 1 for details of Talga’s interests in mining tenements held by the Company. No new joint ventures or farm-in/farm-out activity occurred during the quarter. Some non-core project tenements were rationalised or relinquished during the period under review.

CORPORATE AND INVESTOR RELATIONS

Share Registry Update

During the quarter Talga’s share registry changed to Automic Group. The change took effect from 20th January 2020 (ASX:TLG 20 January 2020).

Measures implemented to manage effect of COVID-19 on Talga operations

Subsequent to the period under review, the Company proactively implemented a range of measures to manage the effect of COVID-19 on its operations (ASX:TLG 2 April 2020). The policies and procedures put into effect focuses on the well-being of Talga’s people, partners and customers. Where possible, Talga staff across the UK, Germany, Sweden and Australia continue working remotely to deliver corporate, operational and product marketing functions.

Dealings with customers are ongoing and development of the Vittangi Anode Project is proceeding with minor interruptions. The Stage 1 DFS finalisation and Stage 2 permit application submission are now targeting Q2 2020.

Activities at Talga’s test facility in Rudolstadt continue, subject to government precautions and at a reduced rate, with priority placed on finalising samples and materials already in production. The Company’s current stocks of Talphite® and Talnode® products are considered sufficient to meet demand in the short term.

Talga’s participation across Innovate UK electric vehicle technology projects and customer graphene programs also continue subject to quarantine restrictions.

To maximise the Company’s capital position, Talga has implemented a group-wide cost reduction programme to reduce fixed and variable costs. As part of the cost reduction programme, the executive team, senior management and the board will undertake significant salary reductions, ranging 20% - 50%, for the remainder of the financial year.

Cash outflow during the period included some major but temporary costs relating to accelerated development of the Vittangi Anode Project in Sweden. These development activities, although ongoing to an extent, have largely been completed and the Company expects to have materially lower cash outflow going forward.

Financial

Talga closed out the 2020 March quarter with A$6.6 million cash-in-bank and was capitalised at ~A$76 million (based on closing price 29 April 2020). Currently the Company has 243.6 million quoted ordinary shares and 11.8 million unlisted options on issue.

This announcement has been authorised by the Board of Directors of Talga Resources Ltd.

Global First as Talga Graphene Coating Begins Commercial-Scale Trial on Ocean-Going Cargo Vessel

Posted By Graphene Council, Thursday, April 23, 2020
Advanced battery anode materials and graphene additives provider Talga Resources Ltd is pleased to announce the commencement of a commercial scale trial of a Talga graphene-enhanced coating applied to a 33,000t container ship. The result is expected to be a range of environmental and economic benefits, which for marine applications includes improved corrosion resistance, decreased metallic paint loss into oceanic ecosystems and increased efficiency through lowering dry-docking cycles.

Believed to be the world’s largest single application of graphene, the 700 m2 coating of the cargo vessel’s hull is part of advanced testing of Talga’s functionalised graphene (Talphene®) additive as a performance booster for existing commercial marine coatings (part of the global 54 million tonne per annum paint and coating market1). The commercial-scale application follows completion of in-house development and patent pending technology that successfully translates graphene’s exceptional mechanical properties into paint and coatings. The result is expected to be a range of environmental and economic benefits, which for marine applications such as shipping and offshore infrastructure includes improved corrosion resistance, decreased metallic paint loss into oceanic ecosystems and increased efficiency through lowering dry-docking cycles.

The freshly coated ship is now at sea and over the coming 12-18 months the Talphene-coated area will be evaluated in the harsh real-life conditions of global cargo shipping.

Talga Managing Director, Mr Mark Thompson: “The maritime coating sector is a very large market and well suited to use of our Talphene® graphene additives for improved environmental and economic outcomes. Additionally, by successfully taking this new product from the laboratory to commercial scale application on a 33,000 tonne ship, being tested across global marine environments, we are showcasing our graphene’s real-world potential as a bulk industrial product.” Marine coatings market

Within the global ~54 million tonne per annum paint and coatings market2, the marine coatings segment is projected to grow to USD$12 Billion by 2024. Drivers for new coating technologies include environmental and regulatory demands, fuel efficiency, construction costs (pre-fabrication) and maintenance costs. Growth in emerging economies such as China, India and Brazil are large volume drivers while in terms of value, the Asia Pacific marine coatings market is projected to grow at the highest CAGR during the forecast period3. Key players operating in the marine coatings market include Hempel (Denmark), Jotun (Norway), AkzoNobel (Netherlands), PPG Industries (US), Sherwin-Williams (US), Chugoku Marine Paints (Japan), Nippon Paint (Japan), Kansai Paint (Japan), Axalta (US), and BASF Coatings (Germany).

Talphene® coating product development

Coatings are one of Talga’s key target products due to the large volume market and graphene’s potential to provide substantial new levels of performance and environmental sustainability. For maritime applications, Talga’s additive development has included multi-stage testing to optimise graphene loadings (i.e. quantities) and Talga’s unique patent-pending dispersion technology for epoxy based commercial primer coating systems. Testing by Talga included industry accepted ASTM prescribed Salt Fog Test (ASTM B117) where steel panels coated with epoxy primer containing Talphene additive showed improved corrosion protection performance compared to ‘state of the art’ commercial systems currently used world-wide in large volumes.

Further evaluation included mechanical performance tests, carried out to ASTM standard by the highly recognised research organisation The Welding Institute (TWI), as the coated surfaces of ships and maritime infrastructure are exposed to considerable abrasion and mechanical damage during service. The results showed a significant improvement in primer performance, including greater adhesion to the substrate (by ~7%), greater interlayer adhesion to the subsequent (antifouling) coating systems (by ~14%) and consistent improvement in abrasion resistance.

These improvements in performance were a notable outcome for this highly optimised industry, indicating that graphene’s exceptional mechanical properties translated into the coating system and warranted commercial-scale trials.

Commercial ship application & trial details

Based on the successful lab results, plans were drawn up for a major commercial scale application and sea trial. A 2-part epoxy based commercial coating system was purchased and mixed with the Talphene additive before dispatch to the ship management company for application during vessel dry docking (carried out every ~5 years for ships this size). The test areas along the ship’s starboard side, both below the water line and above in contact-wear sites, were blast cleaned to remove prior paint systems before the Talphene-enhanced primer coating was applied (next to a test reference coating without Talphene) in two coats, using manual spray systems. A major challenge of the product development was to translate the positive lab-scale tests into practical, large-volume use by on-site commercial applicators. The successful application of the Talphene-enhanced coating without any adverse effect in terms of stability in resin, application, curing and surface features is a highly positive step forward in the commercialisation process. The test areas have been over-coated with the standard topcoats used on the rest of the vessel and marked to ensure identification during service. Periodic inspection will be carried out over the next 12-18 months to determine real world performance.

Next steps

Talga intends to continue development of this Talphene additive for marine coatings under its range of paint and coating additives now trademarked as Talcoat™. The next steps include a trial of the additive as an after-market product, to be mixed into the coatings on-site by the commercial applicators, as opposed to being dispersed by Talga prior to despatch. Talga has also identified a range of potential commercial partners and commenced discussions, under NDA, regarding the incorporation of Talcoat products into their existing and new coating product lines4. The company notes that these negotiations are preliminary, and further updates will be released as and when any definitive commercial agreements are reached.

Successful 60 tonne pilot flotation program supports Talga’s anode market development

Posted By Graphene Council, Friday, January 31, 2020

Battery anode and graphene additives provider Talga Resources Ltd is pleased to announce the successful completion of a 60 tonne pilot-scale processing program producing graphite concentrate - the feedstock for Talga’s planned European battery anode refinery and ongoing customer development programs.

The pilot processing program employed continuous test conditions for numerous key processing stages including crushing, grinding, flotation and concentration using advanced, industrial scale equipment at a Scandinavian toll milling and testing facility. The program achieved the Company’s targeted range of operational and product performance, in line with PFS assumptions, and demonstrated suitability of the process flowsheet for planned commercial production.

Talga Managing Director, Mr Mark Thompson: “This successful increase in processing scale is a positive milestone in progressing our plans for an integrated graphite mine and anode refinery in Sweden. The pilot scale program confirmed some key equipment requirements and production parameters, further improving our in-house processing knowledge and capability for future operations.”

In addition to further validating the first step of Talga’s processing flowsheet for its battery anode production, the pilot program generated information and samples for final detailed engineering design for ongoing DFS work and customer programs.

The process development and refinements of pilot-scale testing highlight the effectiveness of Talga’s preferred production process which uses large-scale European developed quality industrial equipment. Talga’s patent pending purification processes will be used in the downstream refining of the Vittangi graphite concentrate into the Company’s Talnode®-C anode product for use by Lithium-ion battery makers.

Background to scale-up program
Graphite anode is an advanced non-metal product that requires extensive physical validation by cell or battery manufacturers at increasing volumes prior to commercialisation. This is unlike most battery metals (such as lithium, copper or cobalt) that can be sold on a purity basis with little testing.

The addition of several automotive electric vehicle (EV) customers to Talga’s commercial register has driven the requirement to provide more advanced samples for testing, increased industry quality standards (high ISO standards and Six Sigma type quality operations) and most importantly, the need for samples to be sourced from larger production scale equipment.

The Company is currently investing in upscaled equipment and other components of the Talnode-C production supply chain at its European operations to meet ongoing customer qualification programs. Talga is also reviewing its options to more rapidly service the particular demands of automotive customers.

Pilot ore test program details
The pilot ore processing program was based around Talga’s unique and effective production flowsheet developed over several years from a comprehensive range of pilot and laboratory metallurgical programs.

These development programs have translated into a successful Scandinavian production schedule incorporating a 300 kg/hr pilot processing circuit, operating 24 hours per day continuously over 7 days at the facility, with a focus on developing and optimising the ore processing flowsheet.

The pilot operation included commissioning and process optimisation phases run over 15 days and testing the following key unit operations - crushing, milling, roughing, regrinding, cleaning, tailings dewatering and concentrate filtration.

Key areas of the process were tested under locked-cycle conditions simulating commercial plant operation with recycle of process streams allowing further investigation and optimisation of the process conditions, circuit configurations and operational practice.

Vital data was obtained, and targeted recoveries and product quality achieved while exploring a range of primary grinding settings, float cells residence times, regrinding energy and equipment configuration, tailings dewatering and concentrate filtration.

The results and samples from the pilot plant production will form the basis of core information in developing the graphite ore tolling process for near term ramp-up of customer sample production and guide the choice of process plant equipment for the full scale battery anode operation.

Representative samples were also taken during the pilot for further analysis and vendor trial work to support engineering and process validation activities as required.

The next stage of the anode scale-up program is currently underway, incorporating the refining of the concentrate into active anode for distribution to customers via several of Talga’s European process partner sites and at Talga’s German pilot processing facility.

Talga Completes 2nd Commercial Scale Graphene Coating Trial

Posted By Graphene Council, Wednesday, January 22, 2020
Talga Resources Ltd announced the commencement of a new large scale commercial trial of its Talcoat graphene additive for maritime coatings.

At the core of the Talcoat product is Talga’s new patent-pending graphene functionalization technology in the form of an on-site dispersible powder that can successfully add graphene’s exceptional strength into paint and coatings.

Supported by the same shipowner, Talga has provided its next-generation graphene additive to enhance a primer coating successfully applied over a sizeable area of a second large container ship.

Unlike the first trial, the Talcoat product and the 2-part epoxy-based commercial coating system were supplied separately and mixed on-site by the paint applicators before spray application to the vessel during dry-docking.

The application of the coating was successful in meeting all conditions and standards required for ships of this size, confirming the potential of the Talcoat product as a ready-mix component for on-site incorporation by coating companies or paint applicators alike.

To further test the versatility and compatibility of the Talcoat additive, the trial used a commercial coating system from a world-leading coating supplier different from that used in the first trial.

The ocean-going cargo vessel, of similar size to the initial container ship being approximately 225m long and weighing 33,000 tons, has re-entered service at sea where over the next 12-18 months the test area will be evaluated on the performance boost delivered to the coating system.

“We continue taking graphene out of the lab and into the real world with these large scale coating trials underway on cargo ships," Talga Managing Director Mark Thompson said. "This application joins the other large scale clean technology product verticals we have been developing for several years such as graphene-enhanced concrete, plastics and packaging products.”
