摘要:
An electrolyte includes a solvent and an electrolyte salt. The solvent contains at least one selected from ester compounds, lithium monofluorophosphate, and lithium difluorophosphate, and at least one selected from anhydrous compounds. The ester compounds are chain compounds having ester moieties, such as (—O—C(═O)—O—R), at both ends. The anhydrous compounds are cyclic compounds having, for example, a disulfonic anhydride group, (—S(O═)2—O—S(O═)2—).
