The present invention relates to a method for selecting alternative solvents having properties similar to those of the conventionally used solvents. By simplifying the solvent selection process, it is possible to save time, effort, and resources to be consumed by complicated experiments, and the suitable solvents can be quickly selected and applied.

Method for selecting alternative solvent

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 &#x2212;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.
