Abstract
The present invention is directed to an electrochemical cell having plate electrodes housed inside mating “clam shell” casing components. 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. A one piece header containing both a glass-to-metal seal opening for a terminal lead and an electrolyte fill opening is used in conjunction with the clam shell casing.
