[0023] The method for preparing tin-nickel-carbon composite negative electrode material for lithium ion battery of the present invention uses an electrodeposition process to prepare tin-nickel-carbon composite negative electrode material for lithium ion battery; the electrodeposition process is:
[0024] Process (1): graphite powder → surface chemical modification treatment → adding pyrophosphate alloy plating solution → ultrasonic dispersion;
[0025] Process (2): copper foil current collector → activation treatment;
[0026] Process (3): The copper foil current collector obtained in process (2) is used as a cathode, a hard graphite plate is used as an anode, and the plating solution obtained in process (1) is used as an electrolyte to perform electrodeposition coating, and finally a composite coating is obtained.
[0027] The particle size of graphite powder is 5-12μm. The graphite is processed by a ball milling method to obtain graphite powder with a particle size of 5-12 μm.
