| titleOfInvention | Non-aqueous electrolyte with high temperature characteristics and low impedance, its application and lithium ion battery |
| abstract | The present invention relates to a non-aqueous electrolyte with both high temperature characteristics and low impedance, its application and a lithium ion battery. The non-aqueous electrolyte solution of the present invention, based on its total weight, comprises the following components in mass fractions: 70-90% of non-aqueous organic solvent, 5-20% of electrolyte lithium salt and additives; based on the total weight of the non-aqueous electrolyte solution As a benchmark, the additives include lithium difluorophosphate 0.1-2.5%, propane sultone 0.1-2.5%, lithium bisfluorosulfonimide 0.5-3%, tetravinylsilane 0.1-1% and tris(tri(tri) Methylsilane) Phosphate 0.1-1.5%. The invention uses TVS as a high-temperature additive, which inhibits the high-temperature gas production of the electrolyte and the growth of DCR; it is used in conjunction with TMSP that reduces impedance, and a suitable amount is balanced to counteract the increase in the initial impedance caused by the addition of TVS, so as to achieve the electrolytic solution. The liquid achieves the purpose of taking into account high temperature storage and magnification. |
