▎ 摘  要

NOVELTY - Preparation of anode, involves mixing 0.5-1 mol/L anode active material precursor solution, anode active material and surfactant in a ratio of 10 mL: 0.5 g: 0.1-0.3 g to obtain slurry, impregnating porous current collector with the slurry, and calcining. USE - Preparation of anode of lithium-ion battery. ADVANTAGE - The method improves the load of the active material on the anode and electrochemical performance of the lithium-ion battery. The slurry formed by the precursor solution of the anode active material and the anode active material is impregnated into the porous current collector, and the active material can be generated inside and on the surface of the current collector in an in-situ growth manner in the calcining process, so the interface charge transfer performance and binding force between the active material and the current collector is improved.
