A kind of preparation method of carbon-coated cobalt-nickel binary transition metal sulfide negative electrode material |
| abstract |
The invention relates to a preparation method of a carbon-coated bimetallic sulfide negative electrode material for lithium ion batteries. Bimetallic sulfide Co9S8@Ni3S2 was directly prepared by solvothermal method, then coated with polydopamine, and then calcined to obtain NixCoyS@C (x:y is 1:1~2) material. The as-prepared carbon-coated bimetallic sulfide NixCoyS@C materials were used as anode materials for lithium-ion batteries. The synergistic effect between the bimetallic sulfide heterostructures and the carbon-coated structure improved transition metal sulfides as lithium-ion batteries. The volume expansion of the negative electrode material improves the cycle performance of the battery. |
