New stable Fe3O4/C composite material for conversion electrode in solid-state Li-ion batteries

Green Car Congress

Researchers in Europe, with colleagues from Samsung R&D Institute in Japan, have developed a highly stable Fe 3 O 4 /C composite for use as a conversion electrode in all-solid-state Li-ion batteries. In addition, recently a new chemistry has surfaced, allowing to store more Li + by the so-called conversion mechanism.

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. .
