A kind of non-aqueous electrolyte and secondary battery |
| abstract |
In order to overcome the problem that the existing lithium ion battery cannot take into account the high temperature performance and low temperature performance, the present invention provides a non-aqueous electrolyte, including a solvent, an electrolyte salt and a compound shown in structural formula 1: Wherein, R 1 and R 2 are independently selected from C1-C6 hydrocarbon groups or fluorine-containing hydrocarbon groups or fluorine atoms; R 3 and R 4 are independently selected from C1-C6 hydrocarbon groups or fluorine-containing hydrocarbon groups. Meanwhile, the present invention also discloses a secondary battery comprising the above non-aqueous electrolyte. The non-aqueous electrolyte provided by the invention can improve the high temperature cycle of the battery while avoiding the decrease of the low temperature discharge capacity, and take into account the high and low temperature performance of the battery. |
