| titleOfInvention | High-voltage lithium cobalt oxide cathode material, preparation method thereof and lithium ion battery |
| abstract | The embodiment of the invention provides a high-voltage lithium cobalt oxide cathode material which can be used for preparing energy storage batteries of electric equipment such as electric vehicles, intelligent vehicles and terminals and the like 1‑ x Ma x CoO 2 (ii) a Wherein x is more than 0 and less than or equal to 0.05, Ma is a doping element and is selected from one or more elements with the ionic radius range of 68pm-90pm and the ionic valence state of more than or equal to 1. According to the high-voltage lithium cobalt oxide positive electrode material, the lithium position of lithium cobalt oxide is subjected to substitution doping, so that the electrostatic interaction and cobalt dissolution of the lithium cobalt oxide caused by lithium falling out under high voltage are relieved, the structure and the cycling stability of the material are improved, and the material has high capacity and good cycling stability under high voltage. The embodiment of the invention also provides a preparation method of the high-voltage lithium cobaltate positive electrode material and a lithium ion battery. |
