The invention discloses a sulfur-molybdenum-zinc/carbon nano-sheet structure composite material, the particles of which show uniform nano-sheet morphology, the nano-sheet thickness is 2-30 nanometers, and the dispersibility is good; The atomic ratio is 1:4:1, and the carbon content is 12% to 22% by mass. The composite material is made of solid zinc acetate dihydrate, thioacetamide, ammonium molybdate tetrahydrate and glucose as raw materials, and ultrapure water as a reaction medium. , 1 to 4 hours for the reaction, and then calcined at 500 to 700 degrees Celsius. The invention also discloses the application of the composite material in preparing the negative electrode material of the lithium ion battery. Experiments have confirmed that the composite material of the present invention has excellent cycle and rate performance as a negative electrode material for lithium ion batteries, and is expected to have broad applications in the field of negative electrode materials for lithium ion batteries. |
