| titleOfInvention | Lithium ion battery and preparation method thereof |
| abstract | The invention belongs to the technical field of lithium ion batteries, and particularly relates to a lithium ion battery and a preparation method thereof, wherein the preparation method comprises the following steps: (1) preparing a negative electrode material; (2) preparing lithium ion battery electrolyte; slowly adding lithium salt into an organic solvent for multiple times, gently shaking to gradually dissolve the lithium salt, then adding a stabilizer, and slowly stirring to obtain a lithium ion battery electrolyte; wherein the organic solvent accounts for 85-89.8% of the electrolyte, the lithium salt accounts for 10-15% of the electrolyte, and the stabilizer accounts for 0.05-0.2% of the electrolyte; (3) molding the lithium ion battery; winding and molding a positive electrode material, a negative electrode material and a diaphragm, injecting electrolyte, packaging and molding, aging and sealing to obtain the lithium ion battery; the cycle performance of the lithium ion battery is improved by further optimizing the cathode material and the electrolyte. |
