NOVELTY - A composite ternary material preparing method involves pre-treating lithium-nickel-cobalt-manganese-oxide in oven, cooling, placing in a desiccator to obtain lithium-nickel-cobalt-manganese-oxide powder, preparing graphene oxide organic solution by dispersing proper amount of graphene oxide in a reaction kettle, and adding organic solvents to obtain graphene oxide dispersion. The lithium-nickel-cobalt-manganese-oxide powder is added in the kettle, sealed, and mixed with graphene oxide dispersion followed by heating the reaction kettle, cooling, and washing to obtain the finished product. USE - Method for preparing composite ternary material for preparing lithium ion battery anode material. ADVANTAGE - The method enables preparing composite ternary material in simple and cost effective manner. DETAILED DESCRIPTION - A composite ternary material preparing method involves pre-treating lithium-nickel-cobalt-manganese-oxide (LiNixCoyMnzO2) in oven at 120-200 degrees C for 1-3 hours, cooling after grinding, placing in desiccator to obtain lithium-nickel-cobalt-manganese-oxide (LiNixCoyMnzO2) powder, preparing graphene oxide organic solution by dispersing proper amount of graphene oxide in a reaction kettle, adding organic solvents to obtain graphene oxide dispersion. The lithium-nickel-cobalt-manganese-oxide (LiNixCoyMnzO2) powder is added in the reaction kettle, sealed, and mixed with graphene oxide dispersion, followed by heating the reaction kettle, cooling, and washing using organic solvents to obtain the finished product, where the composite ternary material comprises lithium-nickel-cobalt-manganese-oxide (LiNixCoyMnzO2) and graphene oxide, the x is 0.2-0.6, the y is 0.1-0.4, and the z is 0.2-0.5, and chemical formula for composite ternary material is graphene/lithium-nickel-cobalt-manganese-oxide (LiNixCoyMnzO2).
