摘要： A sealing member (positive electrode first sealing member) disposed between a terminal (positive electrode terminal), which is provided on a case of an energy storage device, and the case or between a current collector (positive electrode current collector), which is electrically connected with the terminal, and the case. The sealing member includes a first surface (bottom surface) which faces the case and a second surface (bottom surface) which is opposite to the first surface and faces the terminal or the current collector. A first protrusion is formed on the first surface, the first protrusion surrounding a shaft portion of the terminal. A second protrusion is formed on the second surface, the second protrusion surrounding the shaft portion of the terminal. A protrusion amount of the first protrusion is different from a protrusion amount of the second protrusion.

摘要： 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.
