摘要：NOVELTY - Modified nickel-cobalt-aluminum ternary positive electrode material involves uniformly coating reduced graphene oxide on nickel-cobalt -aluminum nanosize primary particles. USE - Modified nickel-cobalt-aluminum ternary cathode material used for preparation of cathode material for lithium-ion battery (claimed). ADVANTAGE - The method enables to prepare modified nickel-cobalt-aluminum ternary positive electrode material which exhibits rapid charge and discharge capacity of lithium-ion battery and excellent cycle stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing modified nickel-cobalt-aluminum, which involves: (A) taking 10-100 milligram carbon source, Ultrasonically dispersing in water and adding 1-10 g nickel-cobalt-aluminum ternary cathode material to ball mill tank; and (B) adding dispersion, ball milling and drying in vacuum oven to obtain desired product.
