<p>PROBLEM TO BE SOLVED: To improve reliability in long-term performance and to raise voltage- resistance and energy density by allowing an element body to be impregnated with an organic electrolyte comprising a fourth class onium salt before positive and negative poles are electrically shorted to a metal lithium. SOLUTION: An element body wherein an electrode which is, whose main component is carbon-nature material of surface area 100-3000 m2/g, formed on the surface of a metal current-collector is used as positive and negative poles which are faced each other through a porous separator, is housed in a metal case wherein its inside surface is connected electrically to a metal lithium while electrically insulated from the positive and negative poles. An organic electrolyte comprising a fourth class onium salt is injected into the metal case so that the metal lithium is submerged in the electrolyte, and, related to such electric double layer capacitor wherein an element body is impregnated with the electrolyte, the metal case and the positive and negative poles are electrically shorted during use for correction of operational electric potential of the positive and negative poles.</p> |
