US-based CVD graphene developer General Graphene Corporation (GGC) has launched its new Gen3.0 CVD graphene production line. This 20-meters long roll-to-roll based system can produce single- and multi-layer graphene materials on copper films up to 400 mm wide.
GGC says that with the new line, its manufacturing capacity exceeds 100,000 m2/year. The company is now able to supply affordable and highly consistent CVD graphene in industrial volumes.
Mason Graphite has announced the launch of Black Swan Graphene Inc., and the execution of a Definitive Agreement pursuant to which Mason Graphite has agreed, through Black Swan Graphene, to purchase strategic assets related to a patented graphene processing technology from Thomas Swan, a leading UK-based specialty chemical company.
On closing of the joint-venture Transaction, Mason Graphite and Thomas Swan will own respectively 66.67% and 33.33% of Black Swan Graphene, which is expected to proceed to a going-public transaction in the coming months.
Tirupati Graphite has commissioned Stage 1 of the Tirupati graphene and mintech research center (TGMRC) in India. Tirupati says this marks the start of revenue generation at TGMRC and allows the company to advance commercialization engagements.
In Stage 1, the facility can initially produce up to 1 kilogram per day – of graphene oxide ('GO'), reduced graphene oxide ('rGO') and aluminium graphene composite – via the zero-chemical process developed by the company. Ongoing development and expansion of the facility will enable up to 10 kgs per day.
Korea-based Charmgraphene has started to mass produce CVD graphene, using its proprietary roll-to-roll process.
CharmGraphene's graphene on copper and heating element
CharmGraphene's R2R production system can produce 2 meters of CVD graphene per minute (maximum width 300 mm). According to CharmGraphene, its current CVD graphene capacity is about 8,000 sqm per month. The company says it uses use 6 um thick copper foil which reduces copper foil etching time dramatically compare to 35 um thickness copper foil used by other companies.
Lithium Energy, an emerging battery minerals company with two exploration and development projects (the Solaroz Lithium Project in Argentina and the Burke Graphite Project in Queensland), has announced its plans to pursue commercial opportunities for using its graphene in lithium-ion batteries
Testing by the Company has reportedly confirmed its Burke Deposit is well suited for graphene production via electrochemical exfoliation process, via a relatively low cost and environmentally friendly process that produces very high purity graphene products.
