▎ 摘　　要

NOVELTY - The material involves preparing nickel cobalt lithium manganate powder. A graphene thin film is coated with a raw material. Electrolyte solution is added in a reaction container. A tungsten silk is covered on a strip-shaped graphite sheet. A cathode is placed in the reaction container. High offset voltage is provided to the strip-shaped graphite sheet. Graphite oxide reduction is determined in a dual-layer graphene sheet. Large graphite granule is removed by a vacuum filter. The dual-layer graphene sheet is coated with a lithium-nickel-manganese-cobalt material. USE - Method for preparing a high ratio capacity graphene coated lithium-nickel-manganese-cobalt material. ADVANTAGE - The method enables improving capacity of the lithium-nickel-manganese-cobalt and mixing material of nickel and lithium in a convenient manner. DETAILED DESCRIPTION - The reaction container is made of glass or ceramic and plastic material. DESCRIPTION OF DRAWING(S) - The drawing shows a graphical view illustrating a method for preparing a high ratio capacity graphene coated lithium-nickel-manganese-cobalt material.'(Drawing includes non-English language text)'
