Title:
LITHIUM ION ELECTROLYTIC SOLUTION, GEL POLYMER ELECTROLYTE, AND LITHIUM ION BATTERY
Document Type and Number:
WIPO Patent Application WO/2024/083012
Kind Code:
A1
Abstract:
In order to solve the problems of poor liquid retention capacity and poor cycle performance of a gel polymer electrolyte, provided is a lithium ion electrolytic solution, comprising a lithium salt, an organic solvent, a precursor, and an additive, wherein the additive comprises one or two of a zero-dimensional carbon nanomaterial and a quasi-zero-dimensional carbon nanomaterial, and a plasticizer. The gel polymer electrolyte is formed after the described lithium ion electrolytic solution is polymerized, has good liquid retention capacity, can keep good interfacial compatibility with an electrode, improves the interface resistance, and improves the normal-temperature cycle performance of the lithium ion battery. In addition, further provided is a corresponding lithium ion battery.
