Abstract: A method for manufacturing an energy storage device includes a swaging step in which a swaged portion is formed by swaging a tip portion, penetrating a positive electrode terminal or a positive electrode current collector and projecting in a predetermined direction from the positive electrode terminal or the positive electrode current collector, of a shaft portion. In the swaging step, the tip portion of the shaft portion is swaged by a punch which includes a pressing surface, the pressing surface including a punch-side first concave portion which is concaved in the predetermined direction and a punch-side second concave portion which is concaved in the predetermined direction more than the punch-side first concave portion at an inner peripheral side of the punch-side first concave portion.

Abstract: An ultracapacitor that is capable of exhibiting good properties even after being subjected to high temperatures, such as experienced during solder reflow, is provided. The ultracapacitor contains a housing having sidewalls that extend in a direction generally perpendicular to a base. An interior cavity is defined between an inner surface of the base and the sidewalls within which an electrode assembly can be positioned. To attach the electrode assembly, first and second conductive members are disposed on the inner surface of the base. The electrode assembly likewise contains first and second leads that extend outwardly therefrom and are electrically connected to the first and second conductive members, respectively. The first and second conductive members are, in turn, electrically connected to first and second external terminations, respectively, which are provided on an outer surface of the base.
