The volume occupation factor of the fiber in the separator is set not more than 25%. A coin-type electric double layer capacitor is made by using the separator and thereby, a good characteristic can be provided. In addition, a lithium secondary battery having good battery characteristics can be provided by using the separator.

摘要： PROBLEM TO BE SOLVED: To prevent liquid from leaking out of a solid-state electrical double layer capacitor and to enhance the capacitor in electrostatic capacitance per volume by a method, wherein a capacitor is composed of a pair of polarizable electrodes which contain active carbon obtained by activating meso-phase carbon fiber and high-molecular solid-state electrolyte sandwiched in between the electrodes. SOLUTION: A pair of polarizable electrodes are each formed of active carbon obtained by activating mesa-phase carbon fiber. Potassium hydroxide, phosphoric acid, phosphate or the like is used as activator, and an activating temperature is set at about 400 to about 700 deg.C. High-molecular solid electrolyte is sandwiched in between the polarizable electrodes. Ion-conductive high molecules such as polyether of polyethylene oxide, polypropylene oxide or the like or its derivative is used as high-molecular solid-state electrolyte. As a result of this setup, liquid is prevented from leaking out of a solid-state electric double layer capacitor, and the capacitor can be improved in electrostatic capacitance, made to have reduced internal resistance, and enhanced in durability.
