First Graphene (FGR) has announced that it has reached a milestone on its program to develop high performing supercapacitor materials. FGR’s recent work has been focused on the development of an optimized bill of materials for a supercapacitor to deliver high energy and power densities.

First Graphene has now announced that, in a standard test cell, its product PureGRAPH hybrid active materials outperform leading activated carbon materials over 100 cycles. The PureGRAPH materials have a specific capacitance of 140 farads per gram (f/g) while activated carbon cells typically have a specific capacitance of 35 f/g. FGR said this shows that PureGRAPH hybrid active materials can be formulated into an electrode slurry for use in device manufacture.

G6 Materials (Formerly called Graphene 3D Lab) has installed a new pilot-scale graphene oxide (GO) reactor at its Ronkonkoma New York facility.

G6M says that the new reactor increases the company’s GO production capacity five-fold. The first batch of graphene oxide from the New Reactor was produced on November 26, 2021.

Directa Plus has reported its plan to sign an agreement with a global chemicals and materials group, to co-develop products targeting the air and water filtration markets. The company remains unnamed, but is said to be “a major player in the non-woven materials industry” that is based in Italy.

The deal is set to run for an initial period of 12 months and will see the two parties collaborate exclusively to develop specific products for the global air and water filtration markets. If the initial collaboration is successful and the technical results are achieved, the two companies will negotiate a technical and commercial partnership agreement.

Versarien announced its interim financial results for the six months ended 30 September, 2021. Revenues were £3.82 million (up 41% from £2.71 million in H1 2020), while reported net loss was reduced to £3.11 million (down from £4.34 million in H1 2020). At the end of the period, Versarien had £3.46 million in cash and equivalents.

The company is now focused on two main application areas, textiles and concrete - for which it sees excellent opportunities in the near future. Versarien is increasing its production capacity. It has recently acquired graphene manufacturing assets in Spain, which will provide an additional 100 annual ton capacity, it has ordered equipment that will enable it to increase graphene ink production capacity by 12,000 liters per year and it has signed a lease on a new dedicated graphene production facility in Gloucestershire.

Alpine 4 Holdings has announced that it has acquired ElecJet/Real Graphene, entering the field of lithium and graphene battery manufacturing and design.

The Companies are also exploring plans with the State of Indiana to convert its South Bend, Indiana facility into a US battery production facility and bring graphene battery production to the United States.
