▎ 摘　　要

NOVELTY - Preparing graphene carbon surface nickel cobalt lithium manganate ternary anode material comprises (i) dissolving nickel source, cobalt source and manganese source in solvent, introducing graphene agent and urea, mixing uniformly to obtain mixed solution, (ii) heating the mixed solution to 100-100degrees Celsius, reacting for 10-20 hours, cooling, centrifuging and separating, collecting precipitate, washing, dry nickel-cobalt-lithium-manganate composite graphene precursor, and (iii) mixing nickel-copper-lactic acid composite and lithium source, and calcining at high temperature. USE - Graphene carbon surface modified nickel cobalt lithium manganate ternary anode material used in lithium ion secondary battery useful in digital product and energy automobile field. ADVANTAGE - The graphene carbon coating layer effectively protects the electrode active particles, avoids the material surface being corroded by the electrolyte, improves the circulation performance and stability of the material, and improves the multiplying power performance of the prepared battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a graphene carbon surface nickel cobalt lithium manganate ternary anode material.
