| titleOfInvention | Metal-organic framework material-coated ternary positive electrode material and preparation method therefor |
| abstract | A metal-organic framework material-coated ternary positive electrode material and preparation method therefor. The preparation method comprises the following steps: (1) uniformly dispersing a ternary positive electrode material in a mixed solution of absolute ethanol and N,N-dimethyl sulfoxide; (2) sequentially adding, with stirring, zirconium salt and an organic ligand to the dispersion, and fully stirring the dispersion; (3) transferring the uniform dispersion obtained in (2) to a reaction kettle for a solvothermal reaction; (4) taking out the reaction kettle, collecting the product at the bottom, centrifugally washing the product, and drying the centrifugated product to obtain a metal-organic framework material-coated ternary positive electrode material. The method can uniformly coat a layer of metal-organic framework material on the surface of the ternary positive electrode material, and the coating thickness is controllable. The ternary positive electrode material surface-modified by the metal-organic framework material can effectively reduce corrosion decomposition of the ternary positive electrode material in an electrolyte, thereby improving battery cycling stability. |
