A polycarboxylic/ether composite polymer electrolyte derived from two-arm monomer and polyethylene oxide (PEO) was in situ 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.
