| titleOfInvention | Preparation method of metaphosphate coated lithium cobaltate material and lithium ion battery comprising metaphosphate coated lithium cobaltate material |
| abstract | The invention provides a preparation method of a metaphosphate coated lithium cobaltate material, which comprises the following steps: dissolving hydroxide in a phosphoric acid solution, reacting to obtain a dihydrogen phosphate solution, adding cobalt salt, adjusting the pH to 9-13, further reacting, washing the obtained precipitate to be neutral, and drying to obtain a precursor; dissolving the precursor, a lithium source and ethyl cellulose in an organic solvent for ball milling, and drying and calcining the obtained sol mixture to obtain the metaphosphate coated lithium cobaltate material. The metaphosphate coated lithium cobaltate material is obtained by adopting an in-situ polymerization mode, has low cost, is applied to a lithium ion battery, and can improve the performance of the battery. |
