Abstract
An electrochemical capacitor wherein electrode members include polarizing electrodes, whose main ingredient is a carbon material having partially oxidized graphite-like microcrystalline carbon, separators, and collectors is immersed in a organic electrolytic solution, the polarizing electrodes expanding on charging and contracting on discharging. Ions with ionic radii of 0.33 nm or less are used as the electrolyte cations of the organic electrolytic solution. The cell container holding electrode members and the electrolytic solution is provided with stress relaxing structure. Either collectors or separators are elastomers. The separators are sponge-like porous insulator with continuous pores.
