| titleOfInvention | A lithium-ion battery |
| abstract | In order to overcome the problem that the existing high-pressure lithium ion battery has insufficient liquid retention and affects the cycle performance of the battery, the present invention provides a lithium ion battery, which includes a positive electrode, a negative electrode, a glue-coated diaphragm and a non-aqueous electrolyte, and the positive electrode is provided. It comprises a positive electrode material layer, the compaction density of the positive electrode material layer is 3.3g/cc～4.3g/cc, the negative electrode comprises a negative electrode material layer, and the compaction density of the negative electrode material layer is 1.55-1.85g/cc, The glue-coated separator includes a porous substrate and a glue-coated layer disposed on at least one surface of the porous substrate, the glue-coated layer includes PVDF, and the non-aqueous electrolyte includes a solvent, an electrolyte salt and a compound shown in structural formula 1 : wherein, n=0-2; R 1-(5+n) are each independently selected from H, halogen or substituted or unsubstituted alkyl of C1-C10. The lithium ion battery provided by the invention has better liquid-holding capacity, and effectively improves its high-temperature cycle performance and high-temperature storage performance. |
