摘要： PROBLEM TO BE SOLVED: To provide an electric double-layer capacitor that uses a simplified fixation method for a winding type capacitor not to greatly increase the number of parts and has an improved reliability to an external force as a result, and to provide its manufacturing method.
SOLUTION: The winding type capacitor 11 is inserted into a fixing member 16 that is made of shape memory alloy and is deformed like a ring, and it is punt into a metallic case 15. Then, the fixing member 16 is restored to the original shape, thereby bringing the fixing member 16 into contact with the outer circumference of the capacitor 11 and the inner circumference of the metallic case 15. Due to such a structure, the capacitor 11 can be fixed in the same effective manner as in a case where it is fixed by the metallic case 15, resulting in the improved reliability of the electric double-layer capacitor.

摘要： PROBLEM TO BE SOLVED: To miniaturize an electric double layer capacitor enclosed in a square shaped case wherein current collectors of a positive electrode and a negative electrode having polarizable electrode layers on the surfaces thereof are laminated with a separator interposed between them. SOLUTION: The capacitor 7 is formed by making a positive electrode current extraction portion 3a, a negative electrode current extraction portion 3b integrated with a positive electrode current collector 1a, a negative electrode current collector 1b respectively, and disposing them in a opposed relation in the direction perpendicular to the lamination direction of the current collectors, and laminating them integratedly, and then bending them along the laminated body of the current collectors with an insulator 5 being interposed between them. In such a structure, the current extraction portions have no projecting portion so that unnecessary space that does not contribute to an electrostatic capacity becomes very small in the case enclosing the capacitor element, thus the square-shaped electric double layer capacitor can be miniaturized.

摘要： PROBLEM TO BE SOLVED: To provide an electric double layer capacitor which has excellent stability at high temperature and which can impregnate electrolyte in a short time.
SOLUTION: A solution containing at least one type selected from the group consisting of pyridinium salt, imidazolium salt and trimethylhexyl ammonium salt and having a viscosity coefficient at 25°C regulated to 0.1 Pa s or less by adding normal temperature molten salt of 0.1 Pa s or an organic solvent to the normal temperature molten salt is used as the electrolyte. The impregnating time of the electrolyte to a capacitor element is shortened by lowering the viscosity coefficient. The productivity of the electric double layer capacitor is improved. The high stability of the electric double layer capacitor can be ensured by utilizing the low volatility of the normal temperature molten salt.
