New Samsung silicon anode with graphene boosts volumetric capacity of LiCoO2 Li-ion cell 1.5x after 200 cycles; gravimetric capacity the same

Green Car Congress

A team at Samsung Advanced Institue of Technology ( SAIT , Samsung’s global R&D hub) reports in an open access paper published in the journal Nature Communications on a new approach to advance high-capacity silicon (Si) anodes for Li-ion batteries (LIBs) to commercial viability, with a particular focus on improving the volumetric capacity of LIBs.

Nth Cycle says its electroextraction tech significantly reduces transportation costs for Li-ion battery recycling

Charged EVs

Charged : In a typical lithium-ion battery recycling process, would this be an added step that would help what’s currently used, or would it replace things? We have the legacy recyclers, who have been around for a while, recycling other types of batteries, and have moved on to lithium-ion. O’Connor: Yes.
