Title:
GEL POLYMER ELECTROLTYE AND ELECTROCHEMICAL DEVICE COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2023/200313
Kind Code:
A1
Abstract:
A gel polymer electrolyte according to the present invention includes a matrix polymer comprising an oligomer that includes: a fluorine-substituted polyether unit; and at least one acrylate unit at a terminal, and thus can achieve high lithium ion conductivity by achieving the effect of reduced battery resistance due to an increase in the degree of freedom of Li ions due to anion immobilization and stabilization. In addition, due to increased high-temperature durability due to a matrix polymer structure in the gel polymer electrolyte, it is possible to manufacture a lithium secondary battery having improved stability at high voltage and high temperature.
