Abstract: A polymer solid electrolyte having high ion conductivity and interfacial stability is provided. An additive including an organic compound having a highest occupied molecular orbital (HOMO) energy of −8.5 eV or higher is used, which facilitates film formation in a positive electrode due to low oxidation potential. The resulting polymer solid electrolytes have enhanced film formation on the surface of a positive electrode surface and enhanced interfacial stability, while maintaining battery performance. Lithium secondary battery having enhanced performance are also described.
