PROBLEM TO BE SOLVED: To provide a battery improvable in charge/discharge efficiency. SOLUTION: A cathode 21 and an anode 22 are arranged in opposition through a separator 23. The separator 23 is in contact with the electrodes with a thickness of 25μm or smaller. The separator 23 is impregnated with an electrolyte solution. The electrolyte solution contains an imide salt such as a lithium (trifluoromethane) sulfonimide, a lithium-bis (pentafluoroethane) sulfonimide, a lithium (trifluoromethane)(pentafluoroethane) sulfonimide, a lithium (tetrafluoroethylene) sulfonimide, a lithium (hexafluoropropene) sulfonimide, a lithium (octafluorobutene) sulfonimide, a lithium tetrafluoro succinic acid imide, or a lithium hexafluoro glutaric acid imide.
