Patent AT-E400901-T1: [Translated] ONE-PIECE HEAD PIECE FOR HERMETIC BATTERY PANEL FEEDTHROUGH, FILLING AND CLOSURE VERSIONS

An electrochemical cell having plate electrodes housed inside mating "clam shell" casing components (22,24). 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 (70) containing both a glass-to-metal seal opening for a terminal lead (78) and an electrolyte fill opening is used in conjunction with the clam shell casing. <IMAGE>
