Title:
ELECTROLYTE ADDITIVE, ELECTROLYTE CONTAINING SAME, AND LITHIUM-ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/040119
Kind Code:
A1
Abstract:
An electrolyte additive, an electrolyte containing same, and a lithium-ion battery. The electrolyte additive comprises a compound represented by structural formula 1: wherein R1 is selected from halogen atoms and substituted or unsubstituted C1-C12 alkyls; R2, R3, and R4 have the same groups as R1; X is a sulfur atom, dimethylsilyl, methylene, or C2-C12 straight-chain alkylenes; and m is an integer of 0-6. The electrolyte additive effectively inhibits circulating gas production, and improves the high-temperature storage, cycle performance and low-temperature discharge performance of the lithium-ion battery under a high-voltage (4.45 V and above) system.
