| titleOfInvention | Metal sulfide lithium ion negative electrode material and preparation method thereof |
| abstract | The invention provides a metal sulfide lithium ion negative electrode material and a preparation method thereof, wherein the preparation method comprises the following steps: dispersing a zinc-cobalt Prussian blue material serving as a structural template in a buffer solution, adding dopamine hydrochloride for reaction, then carrying out centrifugal washing, and placing the washed solution in an oven for drying to obtain a polydopamine-coated zinc-cobalt Prussian blue material; transferring the obtained zinc-cobalt-Prussian blue material coated with polydopamine to a tubular furnace for high-temperature carbonization to obtain a carbonized product, mixing the carbonized product with a vulcanizing agent at a preset temperature for a vulcanization reaction to obtain a vulcanized product; dispersing the obtained vulcanization product in absolute ethyl alcohol, adding a preset amount of antimony trichloride, uniformly stirring, carrying out hydrothermal reaction, then carrying out centrifugal washing, and placing in an oven for drying to obtain the metal sulfide lithium ion negative electrode material. The preparation method has the advantages of simple process, low cost, environmental protection and no pollution, and the prepared metal sulfide lithium ion negative electrode material has high rate capability and cycle performance. |
