▎ 摘　　要

NOVELTY - The material has an anode provided with a graphene coated lithium manganate, where proportion of the graphene oxide is provided with active material, functional material, anode electric conduction material and bonding material. The anode electric conduction material is lithium ferric nitrate solution, where the anode material is lithium manganate. An electric conduction agent is provided with crystalline flake graphite. USE - Modified graphene coated lithium manganate power anode material. ADVANTAGE - The material solves the lithium ion battery failure caused by case plate defect so as to improve self-discharge of a battery group, and improves lithium battery storing time and ensures apparatus using process by a user without long time charging storage. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a modified graphene coated lithium manganate power anode material preparation method.
