NOVELTY - Preparation of lithium ion battery positive electrode material composite material comprises mixing carbon nanoparticles and graphene in the presence of argon, adding acetylene black and sublimed sulfur, reacting to 150-180 degrees C, adding nano zinc oxide, and reacting. USE - Method for preparation of lithium ion battery positive electrode material composite material. ADVANTAGE - The composite material effectively inhibits the dissolution of intermediate polysulfide in the electrolyte, can effectively keep stability of charging and discharging multiple times, and has better cycle performance.
