Document Type and Number:
WIPO Patent Application WO/2024/083148
Kind Code:
A1
Abstract:
The present disclosure provides a battery, in particular a lithium-ion battery having excellent high-temperature storage performance, fast charging performance, and high safety. Specifically, a stable SEI film is constructed by optimizing a negative electrode binder in a negative electrode sheet and introducing DTD, a compound shown in formula 1, and a carboxylic acid ester organic solvent into an electrolyte, thereby inhibiting dissolution of transition metal ions, reducing the occurrence of side reactions on a positive electrode end, and enabling the lithium-ion battery to have excellent high-temperature performance and fast charging performance.
