A kind of preparation method of high voltage lithium battery precursor doped with cobalt hydroxide |
| abstract |
The invention relates to the technical field of preparation of lithium battery precursors, in particular to a preparation method of high-voltage lithium battery precursors doped with cobalt hydroxide. In the early 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 at a suitable temperature (40-60° C.) and pH value (10.0-11.0), doping 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 sedimenting the supernatant. content, so that the nuclei grow slowly, and finally form dense and uniform large-sized spherical particles. The prepared doped precursor is prepared into lithium cobalt oxide with high specific capacity and excellent cycle performance at voltages above 4.5V. |
