Title:
ADDITIVE, NON-AQUEOUS ELECTROLYTE SOLUTION CONTAINING SAID ADDITIVE, AND LITHIUM-ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/123842
Kind Code:
A1
Abstract:
Provided are an additive, a non-aqueous electrolyte solution containing said additive, and a lithium-ion battery; the additive comprises a compound represented by the structural formula (1): wherein each of R1 to R6 is independently selected from a hydrogen atom, a C1-C10 alkyl group, a C2-C10 alkenyl group, a C2-C10 alkynyl group, and a C6-C10 aryl group. The additive can inhibit the oxidative decomposition of a non-aqueous electrolyte, improve the high-temperature storage performance and the high-temperature cycle performance of the lithium-ion battery in a high-voltage (especially 4.5 V) system, and also improve the low-temperature discharge performance of the lithium-ion battery.
