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.

Rice team uses deep eutectic solvent to leach cobalt, lithium from spent Li-ion batteries

Green Car Congress

The Rice University lab of materials scientist Pulickel Ajayan has used an environmentally friendly deep eutectic solvent to extract valuable elements from the metal oxides commonly used as cathodes in lithium-ion batteries. As a whole, recycling lithium-ion batteries is typically expensive and a risk to workers. Tran et al.
