| titleOfInvention | High-voltage high-energy long-cycle-life lithium cobalt oxide cathode material and preparation method thereof |
| abstract | The invention relates to a lithium cobalt oxide cathode material with high voltage, high energy and long cycle life for a lithium ion battery and a preparation method thereof, belonging to the technical field of new energy. According to the method, from the angle of an intrinsic structure of lithium cobaltate, the occupation of transition metal ions Co in the lithium cobaltate is regulated and controlled through a sintering process, so that one part of the transition metal ions Co is occupied in a 3a position and the other part of the transition metal ions Co is occupied in a 3b position of an R-3m phase, and therefore the long-cycle capacity retention rate, the structural stability of an electrode material, the solid-phase lithium ion transmission capacity and the safety performance of a lithium cobaltate anode material under a high-voltage condition are obviously improved. The method is a solid-phase sintering method, and comprises the steps of preparing a precursor, pre-sintering lithium cobaltate and sintering the lithium cobaltate; the method has the advantages of simple synthesis process, high production efficiency, good product uniformity and the like, and is suitable for large-scale production. |
