Patent ID: 7541111

Claim:
An electrochemical cell comprising: a separator; a pair of electrodes disposed on respective top and bottom surfaces of the separator; and a container for housing the separator, the pair of electrodes, and an electrolyte impregnated in the pair of the electrodes, wherein the container includes: 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, the bottom part and the side part being formed in one piece; a conductive terminal made of a metallic material and penetrating through inner and outer sides of the base member, the conductive terminal having a first surface and a second surface disposed opposite the first surface, the first surface being disposed on the top surface of the bottom part of the base member, and the second surface being disposed in contact with one of the pair of the electrodes; a frame member made of a metallic material and having a first surface and a second surface opposite to the first surface, the first surface of the frame member being joined to an entire rim of a top surface of the side part of the base member; and a cover member made of a metallic material joined to an entire rim of the second surface of the frame member.
