▎ 摘　　要

NOVELTY - The preparation method of lithium carbide sulfate suspension involves (i) taking 5-20 %mass graphene, depositing copper nanoparticles of uniform particle size on the surface of graphene powder, changing the nature of the surface of graphene, and (ii) mixing the graphene powder with a copper sulfate solution, and ultrasonically processing. USE - Preparation of lithium carbide sulfate suspension (claimed). ADVANTAGE - The method enables the preparation of lithium carbide sulfate suspension efficiently with excellent dispersing ability and hydrophilicity, high purity, stability, thermal conductivity, and strength by simple process under controlled conditions.
