Abstract:
A method for preparing a negative electrode material of a lithium ion battery is provided. In the method, a solvent-thermal reaction of a graphite material and a modifier precursor in an organic solvent is conducted to form a reaction product. And then, the reaction product is dried. Next, a heat treatment is applied to the dried reaction product to obtain the negative electrode material. The negative electrode material prepared by the method has improved cycle stability and high current performance.
