Perfect Right Limited (Oovao Powers)—Insights from Hong Kong-based Graphene Producer

Posted By Dexter Johnson, IEEE Spectrum, Friday, June 23, 2017

 

The Graphene Council’s industrial partners span from North America to Europe and all the way to Australia. But our latest industrial partner hails from Hong Kong and as such represents the Council’s first Asian corporate partner.

It is sometimes difficult to learn how Asia-based graphene producers see the graphene marketplace and how they see themselves fitting into the overall scheme of things. So our interview with Mr. Ho, Chairman of Perfect Right Limited, a subsidiary of Oovao Powers Holdings Limited, provided us with a unique opportunity to learn about an Asia-based graphene producer that moved beyond marketing materials.

What we can learn from those marketing materials is that Perfect Right Ltd. developed its low-cost process for producing high-quality graphene this year. What you will learn in this interview is what that process is, how they are functionalizing their graphene and how and when they intend to move up the graphene value chain.

The details contained in this interview will provide us with key insights on how this company sees its place in the marketplace now and well into the future.

Q: Can you please tell us what kind of process you have developed for producing a high-quality graphene in bulk quantities, i.e. chemical vapor deposition, liquid-phase exfoliation, plasma, etc.?

We synthesize graphene with an arc-discharge method.  The electric arc oven for synthesis of graphene mainly comprises two electrodes in the atmosphere of air.  The cathode and anode are both pure graphite rods. As the rods are brought close together, discharge occurs resulting in the formation of plasma.  

Q: How have you improved on one of these processes to make it produce a higher quality of graphene at bulk quantities?

We have enhanced and patented our new production method, including the modification of production equipment, which produces high quality graphene that retains graphene’s desired properties, using a low current to create the arc discharge, effectively lowering the cost of production significantly.  Our solution is also scalable, and we are able to ramp up production of our high quality graphene in accordance with market demand.  We already have full production lines running at our factory, and we plan to expand our production capability as demand for our high quality graphene ramps up.  We are continuing to fine tune various parameters in the production process, resulting in a continuous improvement in the quality of the graphene being produced in both purity and domain size, as evidenced by independent lab test results. Our production process is cost effective and completely environmentally-friendly.

For what applications have you functionalized your graphene? I see that many applications of graphene have been identified on your website, but for what specific applications are you functionalizing your graphene?

We are focused on the functionalizing graphene in the areas of energy storage, supercapacitor, coatings, and focused on utilizing the conductive properties of graphene in various applications.  We are currently working with organizations in academia and industry, developing promising applications in the areas mentioned above, and aim to have commercial applications which are ready for market within the next 12 to 18 months.

What is your business model, i.e. are you producing master batches of functionalized graphene for various device manufacturers or are you producing these functionalized graphene materials for your own device manufacturing? If so, what are those devices or technologies?

We currently have our scalable production lines producing high quality graphene for use in the applications being researched, working in collaboration with organizations in academia and industry to bring to market consumer ready solutions which maximizes the unique properties of graphene.  Our business model is to solidify and scale our graphene production, and in lock step develop commercial applications using our high quality graphene.  We believe graphene applications has so far eluded the wider consumer market due to the lack of high quality and stable graphene supply being made available at cost effective prices.  We believe our production method is the solution, as we will be able to provide high quality graphene at prices which will make the consumer applications cost effective, leading to wider adoption of graphene in even more applications. 

What are the greatest challenges your company currently faces in the marketplace, i.e. cautious customers unsure of a new material for their processes, a stable value chain, etc.?

We believe our challenges are twofold, product differentiation and application. There are numerous graphene producers in the market; however, there seems to be a wide range in terms of quality and supplies available.  We have encountered customers who are either using low quality graphene, or graphene oxide in some cases, where they are not maximizing the potential of their products.  As for application, we believe that is an issue that faces all companies in the graphene space.  Until commercial applications of graphene enhanced products become widespread and the application of graphene in products better understood, we will continue to see a fragmented industry where end users are not able to maximize the potential of graphene in their products.

What do you see as the key to success for graphene establishing a foothold for itself in the marketplace, i.e. a ‘killer app’, standardization in graphene, etc.?

We believe standardization of graphene will go a long way towards the adoption and wide spread use of graphene.  Through our market research and interaction with academia, investment funds, and potential end users, one common theme is that there is a wide range of graphene products already in the market, but the lack of standardization makes it very hard for users to compare products, or to even secure a stable supply for their own use.  Another milestone is to have a wide spread consumer facing application where the advantages of using graphene in that product is immediately recognizable.  Graphene has been in the news for some time, however there are still no breakthroughs in the areas which graphene is known to be good for, e.g. energy storage, applications taking advantage of its conductivity, etc.

Where do you see your company in the next five years?

We see ourselves as being one of the premier suppliers of high quality graphene in the Asia region, and also an enabler of the commercialization of graphene enhanced products, through our partnerships with academia and industry players.  We aim to have graphene enhanced products on the market within the next two years, and will focus on projects where the successful commercialization of that product will help push the entire graphene industry forward.
