▎ 摘　　要

NOVELTY - Negative electrode material comprises lithium zinc titanate or reduced graphene oxide (RGO) nanoparticles, polyvinylidene fluoride and acetylene black in a mass ratio of 70:20:10. USE - Negative electrode material for lithium ion battery. ADVANTAGE - The negative electrode material enables to obtain batteries having higher specific capacity and better cycle stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing negative electrode material, which involves: (A) mixing 500 mg titanium dioxide, 456.6 mg zinc acetate, 424.4 mg lithium acetate, 300 mg lithium chloride, 200 mg potassium chloride into a ball mill jar for milling for one hour; (B) placing the resulting mixture in a muffle furnace for calcining at 600 degrees C for two hours; (C) washing the resulting product with water; (D) drying the washed product to give lithium zinc titanate nano-particles; (E) carrying out hydrothermal reduction at 180 degrees C to prepare graphene airgel and lithium zinc titanate particles; and (F) ball milling the obtained graphene airgel and lithium zinc titanate particles in a high-energy ball mill jar for 2 hours to prepare the negative electrode material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic X-ray powder diffraction pattern of the negative electrode material.
