摘要: A battery capable of improving the energy density and improving the cycle characteristics is provided. The battery includes a spirally wound electrode body, in which a cathode and an anode are wound with a separator and an electrolyte in between. The open circuit voltage in full charge is in the range from 4.25 V to 6.00 V. The electrolyte contains an electrolytic solution and a polymer containing vinylidene fluoride as a component. The polymer containing vinylidene fluoride as a component has high oxidation stability. Therefore, even when the battery voltage is raised, oxidation and decomposition of the electrolyte and the separator can be inhibited.
