Abstract

A graphite composite negative electrode material, a preparation method therefor and an application thereof. A coating layer formed by mixing a plurality of substances is coated on the surface of graphite, the high theoretical specific capacity of titanium niobate is utilized, and carbon nanotubes and amorphous carbon are added in an auxiliary manner, the carbon nanotubes form a network structure, and the amorphous carbon stabilizes the structure of the material, which jointly improve the structural stability of the material in the charging and discharging process, and improve the first efficiency and the cycle performance of the material.
