▎ 摘  要

NOVELTY - The preparation method of anode material involves dissolving functionalized graphene in a dispersion medium to form suspension (A), mixing active catalytic nanoparticles with the suspension (A) to orient the active catalytic nanoparticles to the unsaturated sites and defects of the graphene, where the active catalytic nanoparticles are nano-metal ion or nano-metal ion complex, then adding reducing agent, reducing active catalytic nanoparticles to metal atoms at unsaturated sites and defect sites of the graphene to form solution (B), mixing iron phosphate, lithium source and one-dimensional nanowire with solution (B), drying and sintering under protective gas atmosphere, carrying out high-temperature solid phase catalytic reaction and then cooling to room temperature. USE - The method is useful for preparing anode material for lithium ion battery. ADVANTAGE - The method enables safe preparation of anode material with excellent conductivity, discharge specific capacity, high-rate charging and discharging performance, cycle performance and multiplying power performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for anode material prepared by the method.
