Abstract
The present invention is directed to an electrochemical cell having plate electrodes housed inside mating “clam shell” casing components. Also, the present casing design allows for indentation structures in the casing components by virtue of them being stamped metal parts. Such indentations are not possible with traditional cylindrical and prismatic casing designs. When mated together, the casing components are form-fitting with respect to the internal battery structure so as to reduce the overall size of the electrochemical package. This provides the cell with the greatest amount of energy per unit size.
