  "textContent": "According to the present invention, an electrolyte is composed of one or more lithium salts of asymmetric imides each having a perfluoroalkyl group, or a mixed salt of a lithium salt of an asymmetric imide having a perfluoroalkyl group and a lithium salt of a symmetric imide having a perfluoroalkyl group. The composition ratio of the one or more lithium salts and the mixed salt is expressed by (lithium salt of asymmetric imide)x(lithium salt of symmetric imide)1-x (wherein x is from 0.1 to 1.0) in terms of the molar ratio; the asymmetric imide lithium salt is (C2F5SO2) (CF3SO2)NLi or (C3F7SO2) (CF3SO2)NLi; the symmetric imide lithium salt is (CF3SO2)2NLi; and the composition of an electrolyte solution according to the present invention contains 1.0 mole or more but less than 2 moles of a solvent per 1 mole of the one or more lithium salts or the lithium salts of the mixed salt.",
