Abstract
An electrolytic solution capable of inhibiting self-discharge even under the high temperatures and a battery using the electrolytic solution are provided. A spirally wound electrode body in which a cathode and an anode are wound with a separator in between and spirally wound is included inside the battery can. An electrolytic solution is impregnated in the separator. The electrolytic solution contains ethylene sulfite, vinylene carbonate, LiPF, and a light metal salt such as lithium difluoro[oxalato-O,O']borate in a given range. Thereby, the self-discharge can be inhibited even under the high temperatures.
