▎ 摘　　要

NOVELTY - Anode material comprises lithium iron phosphate, lithium vanadium phosphate and graphene, and the lithium iron phosphate and lithium vanadium phosphate are substrates. The graphene is coated with lithium iron phosphate and lithium vanadium phosphate, and the coating amount of the graphene is 2-6 wt.% of the substrate material. The lithium vanadium phosphate is composed of a lithium source, a vanadium source, a phosphorus source, and 4-16 wt.% first carbon source in a molar ratio of 2.8-3.4:2.8-3.4:2 and the lithium iron phosphate: lithium vanadium phosphate = (1-x):x, where x= less than or equal to 3-10%. USE - The anode material is useful in lithium vanadium phosphate battery. ADVANTAGE - The material has good grinding effect and meets the technological requirements. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the anode material, comprising (a) adding the lithium source, the vanadium source, the phosphorus source, and the first carbon source into a cylinder, starting a pushing device, a first rotating device and a second rotating device to grind and mix the raw materials in the cylinder, (b) drying the raw material to obtain a precursor, (c) pre-sintering the precursor in an inert atmosphere to obtain lithium vanadium phosphate pre-sintered powder, and (d) mixing the lithium vanadium phosphate pre-sintered powder with lithium iron phosphate, adding a second carbon source for grinding, and placing the obtained product in an inert atmosphere for sintering; and (2) preparation device. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of the preparation device.
