UVA researchers devise method for converting retired Li-ion anodes to graphene and GO

Green Car Congress

Researchers at the University of Virginia (UVA) have devised a process for converting retired Li-ion battery anodes to graphene and graphene oxide (GO). So far, only 1% of end-of-life Li-ion batteries have been recycled. Here, graphite powders from end-of-life Li-ion battery anodes were used to fabricate graphene. .

Aqua Metals and 6K Energy partner to develop low-carbon CAM precursors for Li-ion batteries

Green Car Congress

The companies have initiated the partnership with a non-recurring engineering (NRE) agreement to develop low-carbon technology for the conversion of critical metals—first virgin and later recycled material—into battery-grade cathode active material (CAM) precursors, which are essential to 6K Energy’s advanced cathode manufacturing.
