The latest Sony graphene news:
Graphene Laboratories recently signed a two-year strategic alliance agreement with Canada's Lomiko Metals, the owner of several resource properties containing high-grade graphite. Graphite Investor News posted an interesting interview with Lomiko Metals' CEO, A. Paul Gill.
Mr. Gill says that he sees a "huge market" for graphene, as billions of dollars have already been spent on research and development. Gill says that Graphene Labs alone have sold graphene products to over 4,000 customers, including Ford, Sony, Samsung, LG, the US Army and NASA.
Sony has developed a new graphene producing process that use a roll-to-roll method. They have built a machine that can produce graphene sheets up to 100 meters in length (23 cm width), and the resulting sheet is the largest area graphene sheet in the world by far (the previous record was Samsung's 40" sheet from back in 2011).
Sony's new process integrates CVD and roll-to-roll, at a temperature of 1,000°C. The idea is to directly apply a current to a copper (Cu) foil that is the catalyst of graphene and a substrate for the CVD method so that only the Cu foil is heated. As a result, the thermal load on the entire machine was drastically reduced.
