| titleOfInvention | A kind of cyclic carbonate additive containing silicon oxygen segment, lithium ion battery electrolyte and lithium ion battery |
| abstract | The present invention provides a cyclic carbonate-based additive containing a silicon-oxygen segment, and the additive has a structure as shown in formula (I). The cyclic carbonate derivatives containing silicon-oxygen segments with specific structures and groups are added into the electrolyte system as a lithium ion battery additive, and the cyclic carbonates form a film on the negative electrode of the battery while converting the high molecular weight The introduction of the silicon-oxygen chain segment into the SEI film can improve the stability of the SEI film, thereby improving the high and low temperature and cycle performance of the battery. Moreover, the lithium ion battery electrolyte provided by the present invention is obtained by compounding a cyclic carbonate additive containing a silicon-oxygen chain segment with a lithium salt and an organic solvent, which can effectively improve the high and low temperature performance and cycle performance of the battery, and the properties of the obtained electrolyte It is stable and can be applied to various lithium-ion battery systems. It is a multi-purpose lithium-ion battery electrolyte with a wide range. |
