Title:
SOLID ELECTROLYTE AND LITHIUM ION BATTERY COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/046181
Kind Code:
A1
Abstract:
The present application provides a solid electrolyte and a lithium ion battery comprising same. The solid electrolyte of the present application comprises a polymer and a lithium salt; the polymer comprises a first structural unit from an olefin compound containing a substituted or unsubstituted ureido group; and the olefin compound containing the substituted or unsubstituted ureido group further comprises at least one cyclic group. The polymer in the solid electrolyte of the present application contains the cyclic group, so that the free movement of lithium ions in the solid electrolyte is facilitated, and thus, the solid electrolyte has higher ionic conductivity.
