| titleOfInvention | A preparation method of high-voltage lithium battery precursor doped cobalt hydroxide |
| abstract | The invention relates to the technical field of preparation of lithium battery precursors, in particular to a preparation method of a high-voltage lithium battery precursor doped with cobalt hydroxide. In the initial stage of the reaction of the present invention, a large number of cobalt hydroxide crystal nuclei are formed at a relatively high pH value (11.5-12.5), and then doped with element ions, Co-precipitation reaction occurs between cobalt ions and sodium hydroxide to obtain a single-phase doped cobalt hydroxide solid solution Co 1‑x M x (OH) 2 ; the solid solution of the reaction system is controlled by adding ammonia water as a complexing agent and settling the supernatant. Content, so that the crystal nuclei grow slowly, and finally form dense, uniform large-diameter spherical particles. The prepared doped precursor is prepared into lithium cobalt oxide with high specific capacity and excellent cycle performance at a voltage above 4.5V. |
