COMPOSITE POLYMER ELECTROLYTE (CPE) MEMBRANES FOR SECONDARY SOLID STATE LI-METAL CELLS AND PROCESS FOR THE PRODUCTION THEREOF

摘要

The present invention relates to a curable composition for preparing a composite polymer electrode, the curable composition containing: (A) a Li-ion conducting solid electrolyte whose general composition has the formula: Li_7+x-yM^II_xM^III_3-xM^IV_2-yM^vO₁₂ wherein M^II, M^III, M^IV, M^V are species of valence II to V; where 0 ≤ x 3, preferably 0 ≤ x ≤ 2; and 0 ≤ y 2 preferably 0 ≤ y ≤ 1; (B) a polymer; (C) a lithium sa (D) an active plasticizer; and (E) a photoinitiator. The invention also relates to a process of preparing the curable composition, cured compositions and films derived from the curable composition, and solid-state lithium batteries whose solid electrolyte layer contains a cured composition or a cured film according to the invention.
