When we first spoke to William Blythe back in 2016, we were trying to get a handle on how a 170-year-old specialty chemical company found itself involved as a major graphene producer. Now nearly two years later we got to visit with the company again to see what’s changed from since we last spoke.
For those of you who would like more regular updates on what William Blythe is doing and thinking about when it comes graphene, you can visit their blog. And while there you can order some material on the same site.
Q: When we spoke to you 18 months ago, William Blythe expected to boost graphene oxide production to the tonnage scale within the next 6-12 months from a lab production level of around 20Kg. Has that production capacity increase happened?
A: William Blythe has definitely seen an increase in demand for graphene oxide since we last spoke. We have been working on scale up of all three of our graphene oxide products, with significant investments made and planned to ensure we always stay ahead of our customers’ needs. As application development has been slower than originally predicted by our customers, we have been able to scale to an interim production capacity of about 200 kg pa.
Q: At the time we spoke last, William Blythe was investing heavily in R&D, focusing on innovation and product development. How has that program developed over the last 18 months?
A: William Blythe has continued building its R&D program and has added several projects since we last spoke. One significant area of investment is in the energy storage sector, with a commitment to spend £1m over the next 3 years in energy storage research. One of these projects is in collaboration with the National Graphene Institute at the University of Manchester and aims to develop novel anode materials. As a company, we are very committed to developing the materials needed to enable the exciting technologies needed for the future.
Q: Can you also address along these lines how your supply line has developed, i.e. what are the expectations of your customers in terms of batch-to-batch consistency?
A: William Blythe’s customers, across our whole product range, always require the highest level of batch-to-batch consistency. Our products are generally used in demanding applications, where the performance of the product could be hugely affected by small variations in either the chemical or physical properties of the materials we supply. We pride ourselves on offering consistently high-quality products. Both the quality and batch-to-batch consistency of our graphene oxide has been commended by several customers.
Q: Are you still supplying strictly graphene oxide or have you branched out to other graphene products, such as single-crystal monolayer graphene? Why have you chosen one product approach, or the other?
A: As we discussed previously, William Blythe is an inorganic specialty chemicals manufacturer. The chemical exfoliation route we use to synthesize our graphene oxide is very well aligned with our core capabilities, which means we are very well positioned to scale the process effectively and successfully.
Q: We discussed ad hoc industry standards for graphene last time we spoke. Have those become more formalized? And what is the state of graphene standardization across producers?
A: A lot of work is taking place on standardization of graphene materials, however the early standards are more focused on graphene as opposed to graphene oxide. While standards are now being written and the first standards are now published, there is still a need to get the wider market on board as terminology is not always being fully understood and adopted by those in the graphene community.
Q: A year-and-half ago, William Blythe expressed confidence that graphene "will be well established in the supply chain of several industries within the next 5 – 10 years”. Has anything occurred since that then enforces that belief, or perhaps you have become more cautious?
A: Based on the work we know of in this market, the forecast of graphene oxide being well established in some industries by 2026 is very realistic. William Blythe is, as you know, working on increasing production capacity of their graphene oxide to meet customer demands over the coming years. While some applications are commercializing right now, William Blythe is also working on several longer-term projects, we expect these applications to take several years to commercialize, but would still anticipate commercial volume demand in these areas before 2026.
