▎ 摘　　要

NOVELTY - Lithium vanadium phosphate composite modified lithium manganate material has a double-layer coating on the surface. The outermost layer is a lithium vanadium phosphate coating layer, and a carbon coating layer is provided between the lithium vanadium phosphate and the main material. USE - Lithium vanadium phosphate composite modified lithium manganate material used in lithium ion battery anode material. ADVANTAGE - The synthesis method of lithium vanadium phosphate composite modified lithium manganate material is simple and efficient. The lithium vanadium phosphate composite modified lithium manganate material has uniform element distribution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing lithium vanadium phosphate composite modified lithium manganate material, which involves: i. mixing manganese dioxide, lithium source and carbon source to obtain carbon-coated lithium manganate (LiMn2O4) material, where lithium source is selected from lithium carbonate and lithium hydroxide; ii. weighing a certain amount of carbon-coated lithium manganate material, dispersing it in an aqueous solution, adding vanadium salt, lithium salt, phosphate precipitant, and organic complexing agent, reacting for a period of time, washing with water, alcohol, and drying to obtain a solid mixture; iii. calcining the obtained mixture to finally obtain a phosphate composite modified lithium manganate material.
