▎ 摘　　要

NOVELTY - Lithium carbon dioxide battery cathode material comprises aminated graphene oxide. The aminated graphene oxide is prepared by mixing graphene oxide, an amination reagent and water, and undergoing a hydrothermal reaction. USE - Lithium carbon dioxide battery cathode material for lithium carbon dioxide battery cathode (all claimed). ADVANTAGE - The preparation method of aminated graphene oxide in the positive electrode material of the lithium carbon dioxide battery is simple, and solves the problems of large charge-discharge potential difference and poor cycle performance of high-capacity batteries. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing lithium carbon dioxide battery cathode, which involves mixing lithium carbon dioxide battery cathode material, binder and organic solvent to obtain a slurry, coating the slurry on the surface of carbon paper, and drying at 70-90 degrees C to obtain the desired product.
