Document Type and Number:
WIPO Patent Application WO/2024/080602
Kind Code:
A1
Abstract:
The present invention relates to a non-aqueous electrolyte for lithium secondary batteries, including a novel electrolyte additive, and a lithium secondary battery comprising same. More specifically, the present invention relates to a non-aqueous electrolyte for a lithium secondary battery, the non-aqueous electrolyte including an additive capable of forming a stable film on an electrode surface. In addition, the present invention relates to a lithium secondary battery that comprises the non-aqueous electrolyte, whereby the lithium secondary battery has enhanced high-temperature lifespan performance and is restrained from thickness expansion when stored at high temperatures, with resultant excellent high-temperature storage performance.
