▎ 摘　　要

NOVELTY - Lithium-ion battery cathode material, is claimed. The anode material of the lithium ion battery is lithium iron phosphate anode material coated with lithium phosphate in situ. USE - Used as lithium-ion battery cathode material. ADVANTAGE - The lithium iron phosphate is similar to spherical shape, the granularity is uniform and controllable, and at the same time, the lithium iron phosphorus can reach the coating effect of nano level, improving the electrochemical performance of the lithium phosphate. The preparation process is simple, the operation difficulty is low, the secondary coating process is avoided, the process steps are reduced and the production cost is reduced. The raw material cost is low. The atoms in the raw material are basically entered into the final product, the atom utilization rate is high, there is no pollution, it avoids the carbon dioxide discharge led into the carbon atom trigger reaching the purpose of energy saving and emission reduction. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparation method of lithium ion battery anode; and lithium ion battery.
