| titleOfInvention | Formation method of lithium battery, lithium battery and preparation method thereof |
| abstract | The application provides a lithium battery formation method, a lithium battery and a preparation method thereof. The formation method of the above-mentioned lithium battery includes the following steps: obtaining the cell after liquid injection and packaging, the negative electrode material of the cell includes a silicon-based negative electrode material; performing the first pressure charging pretreatment on the cell, so that the electric quantity of the cell is 30% SOC ~ 70% SOC; perform static discharge operation on the cells after the first pressure charging and pre-treatment to obtain pre-formed cells; perform liquid rehydration treatment on pre-formed cells so that the electrolyte can be replenished into pre-formed cells In the core: perform the second pressure charge preconditioning treatment on the preformed battery cell after the liquid replacement treatment, so that the electric quantity of the preformed battery cell is 85% SOC-100% SOC. The above-mentioned formation method of a lithium battery can effectively improve the stability of the SEI film of the lithium battery based on the silicon-based negative electrode material and the retention of the electrolyte. |
