| titleOfInvention | Core-shell structure ZnS@C microrod as negative electrode material for lithium ion battery and preparation method thereof |
| abstract | The invention belongs to the technical field of negative electrode materials for lithium ion batteries, and provides a core-shell structure ZnS@C microrod of negative electrode material for lithium ion batteries and a preparation method thereof. The preparation steps are as follows: dissolving zinc sulfate heptahydrate in ethylene glycol and pure water In the mixed solvent, add oxalic acid dihydrate, stir, and perform hydrothermal treatment in an autoclave to obtain zinc oxalate dihydrate micro-rod precursor; (2) anneal the zinc oxalate dihydrate micro-rod precursor in argon to obtain zinc oxide micro-rods (3) carbon-coated ZnO microrods with resorcinol and formaldehyde to obtain ZnO@RF; (4) annealing the sulfur source and ZnO@RF in an inert atmosphere in a quartz boat to obtain the final product ZnS@RF C microrod composites. The size of the material is three to ten microns, with high purity, strong crystallinity, and uniform morphology; micron-scale materials are used for the negative electrode of lithium-ion batteries, which can reduce the irreversible loss caused by the SEI film during the first charge and discharge process, and the first Coulomb efficiency higher. |
