NOVELTY - Preparing a composite anode material involves mixing graphene oxide, nitrogen source, lithium source, iron source and phosphorus source, and then performing a hydrothermal reaction to obtain a precursor, where the mass ratio of nitrogen source to graphene oxide is (3-9):1, and mixing the precursor with a carbon source, and calcining to obtain the composite positive electrode material. USE - Method for preparing a composite anode material for lithium ion battery (claimed). ADVANTAGE - The method enables to prepare anode material with good morphology and conductivity, and penetration of the electrolyte into the anode is enhanced, the reactive sites are increased, and the specific capacity is higher and the cycle stability is better.
