▎ 摘　　要

NOVELTY - Manufacture of cathode active material involves mixing a first quantity of copper hexafluorosilicate hexahydrate, with a second quantity of graphene oxide in an aqueous graphene oxide solution to obtain an aqueous mixture, heating the aqueous mixture to produce a copper fluorosilicate/graphene oxide material, freeze drying the obtained material and heating the material under air flow to produce cathode active material comprising copper fluoride-graphene nanocomposite. USE - Manufacture of active material used for forming cathode for battery such as primary lithium-ion battery and secondary lithium-ion battery (all claimed). Uses include but are not limited to pacemakers, remote patient monitoring systems, sensors, electric vehicles, hybrid electric vehicles, military equipment and radio. ADVANTAGE - The method enables manufacture of active material provides the battery having excellent electrochemical performance, diffusion coefficient and electroconductivity, and structural stability. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) cathode active material, which comprises a nanocomposite of graphene and copper fluoride; (2) cathode, which comprises the active material; (3) lithium-ion battery; and (4) manufacture of copper fluoride nanoparticles.
