The present invention provides a capacitor which can reduce resistances from an element assembly to terminals, which can reduce inductance, and which can reduce time for producing the element assembly even in a case where the terminal is provided only on one side of an outer casing. The element assembly 101 is formed by winding electrode bodies 103A and 103 so that end strip portions 108A and 108B of the respective electrode bodies 103A and 103B protrude on the other side from each other from separators 5A and 5B along the longitudinal directions of the separators 5A and 5B. From both ends of spiral shape of the element assembly 101, end strip portions 108A and 108B of the electrode bodies 103A and 103B are independently exposed, and to the end strip portions 108A and 108B, current collector plates 141A and 141B are bonded respectively. Further, the current collector plate 141A is connected with a terminal 33A, and the current collector plate 141B is connected with a terminal 33B, by a short tab portion 151A and a long tab portion 151B respectively.

摘要:
A process for producing a carbon material for an electric double layer capacitor electrode, including activating a graphitizable carbon or a graphitizable carbon source to have its pore volume in the range of 0.6 to 1.5 cm3/g, and imparting mechanical impact force to the graphitizable carbon or the graphitizable carbon source activated in the activating step to reduce the pore volume to at most 75% of that before the mechanical impact force is imparted.
摘要:
A storage device, which has a simple structure and a low connection resistance and is robust, and which is ease to mount is provided. In the storage device, an L-shaped aluminum busbar 157 protrudes from the center of the top of a sealing plate 41 to the right. The busbar 157 has a barrel portion 157a and a projecting part 157b horizontally protruding from the top end of the barrel portion 157a. A terminal hole 159 is made in an end of the projecting part 157b, so that the positive electrode of another unitary cell to be connected in series can be connected. The barrel portion 157a of the busbar 157 is welded to the sealing plate 41, and the length of the projecting part 257b is minimized. Accordingly, the device is robust and has a low resistance, and consequently can deal with a large current.
