Methods And Systems For Processing And Recycling Of Carbonaceous Materials

Abstract

Provided herein are methods of processing carbonaceous compositions, recycling battery materials, and producing lithium and/or graphene from carbonaceous compositions or spend battery materials. Also disclosed herein are compositions formed from carbonaceous materials and recycled battery materials. The methods may include disposing carbonaceous electrodes in a fluid to form a composition, carbonaceous electrodes comprising graphite, separating a fluid from the composition; combining the fluid with an alkaline composition to form a precipitate, combining with an acidic composition, filtering the acidic composition, combining a surfactant; and shearing to form a dispersion, the dispersion comprising graphene.
