Fig.4b.tif from A polycarboxylic/ether composite polymer electrolyte via <i>in situ</i> UV-curing for all-solid-state lithium battery

A polycarboxylic/ether composite polymer electrolyte derived from two-arm monomer and polyethylene oxide (PEO) was <i>in situ</i> synthesized on the cathode. The composite electrolyte exhibits a high ionic conductivity of 3.6 * 10⁻⁵ S cm^–1, high oxidation stability, excellent stability towards Li metal and makes Li/LiFePO4 present good cyclic and rate performance at 25°C.
