| titleOfInvention | Preparation method of vanadium-based cathode material based on surface modification to enhance cycling stability |
| abstract | The present invention provides a method for preparing a vanadium-based positive electrode material with enhanced cycle stability based on surface modification. Formic acid is used to acidify a vanadium source dissolved in deionized water to obtain a first mixed solution, which is then added to the first mixed solution. Cobalt source and lithium hydroxide are stirred to obtain a second mixed solution, and the second mixed solution is transferred to an autoclave for hydrothermal reaction to obtain a flocculent solid product; the flocculent solid product is placed in a specific gas in a flowing state, The surface-modified vanadium-based positive electrode material is obtained by standing at a certain temperature; wherein, the vanadium source is a vanadate containing ammonium ions, and the cobalt source is an acid salt containing cobalt ions. In the present invention, vanadate with ammonium ion is used as vanadium source, cobalt ion in acid salt is used as intercalation metal ion, and zinc metal is used as negative electrode material to assemble the half-cell with ultra-high mass specific capacity. Low-temperature annealing in a specific gas environment can significantly improve the charge-discharge cycle performance of the battery. |
