▎ 摘　　要

NOVELTY - A modified graphene doped lithium manganate battery cathode material comprises 45 pts. wt. graphene oxide, 45 pts. wt. lithium manganate, 45% solution of 20 pts. wt. lithium iron nitrate, 2 pts. wt. flake graphite and 2 pts. wt. adhesive. USE - Modified graphene doped lithium manganate battery cathode material (claimed). ADVANTAGE - The modified graphene doped lithium manganate battery cathode material overcomes the defect of failure of lithium ion battery due to self discharge of the protective plate, improves the self discharge of the battery pack, prolongs the storage time of lithium battery and ensures that users can store a long time without charging the use of electrical appliances. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation of modified graphene doped lithium manganate battery cathode material.
