▎ 摘　　要

NOVELTY - A graphene and lithium-containing materials preparation method involves crushing graphite electrode from used lithium battery, adding to reactor containing solution, applying external force and electrifying. USE - Method for preparing graphene and lithium-containing materials. ADVANTAGE - The method enables preparing graphene and lithium-containing materials with suitability for heat dissipation, supercapacitor, metal air battery, catalyst carrier and conductive agents in a simple and highly efficient manner at low cost by effectively controlling size of graphene and avoiding doping of metal ion impurities, such as lithium.
