  • Patent number: 7541111
    Abstract: An electrochemical cell has a container housing a separator and a pair of electrodes impregnated with an electrolyte. The container has a base member having a bottom part and a side part disposed on a top surface of the bottom part along an outer rim of the bottom part. A metallic conductive terminal has first and second opposite surfaces penetrating through inner and outer sides of the base member. The first surface of the conductive terminal is disposed on the top surface of the bottom part of the base member. The second surface of the conductive terminal is disposed in contact with one of the pair of the electrodes. A metallic frame member has first and second opposite surfaces, with the first surface being joined to an entire rim of a top surface of the side part of the base member. A metallic cover member is joined to an entire rim of the second surface of the frame member.

  • Patent number: 7311995
    Abstract: An electrochemical cell has an outer case formed of one of ceramics and glass. An electrochemical cell element is hermetically sealed in the outer case. The electrochemical cell element contains a positive pole, a negative pole, and a non-aqueous electrolyte containing an organic solvent. A metal layer is formed on an edge of the outer case. A sealing plate is resistance welded to the metal layer. The sealing plate is made of an alloy containing, in weight percentage, Co by 1 to 50%, Ni by 1 to 70%, Fe by 20% or higher, Cr by 10% or lower, Mn by 2.0% or lower, Si by 1.0% or lower and C by 1.0% or lower.

  • Patent number: 6733544
    Abstract: A method for producing an electrical double layer capacitor comprising the steps of assembling together components comprised of a positive electrode, a negative electrode, a non-aqueous solvent, an electrolyte containing a supporting salt, a separator, and a gasket to form a coin- or button-type electrical double layer capacitor, heating the assembled coin- or button-type electrical double layer capacitor so that a temperature profile of the heating step is approximately the same as a temperature profile of reflow soldering, and welding an outer connection terminal to the heated assembled coin- or button-type electrical double layer capacitor after the heating step.

  • Patent number: 6509714
    Abstract: A secondary battery or capacitor fitted with terminals and occupies less area on a packaging substrate. Either one of the positive and negative terminals is mounted within the outer surface of the secondary battery or capacitor. This reduces the area occupied by the secondary battery or capacitor fitted with terminals on the substrate. At least one step is formed on the terminal positioned opposite to the substrate. This prevents electrical shorting between the positive electrode can and the negative terminal.
