Abstract:
1. A method for providing an electrochemical cell, comprising the steps of: a) forming a first casing member and a second casing member, the first casing member having a first surrounding side wall extending to and meeting with a first major face wall and the second casing member having a second surrounding side wall extending to and meeting with a second major face wall; b) providing a separate header having a surrounding sidewall extending to an upper surface and a lower surface and sealing the header in a casing opening provided in the first casing member, the casing opening being sized to receive the header with the header surrounding sidewall contacting the first casing member at the casing opening but with the header being incapable of completely moving through the casing opening; c) providing at least one header opening in the header; d) positioning an anode and a cathode in one of the first and the second casing members; e) connecting the anode and the cathode to respective terminals, wherein one of the terminals is a terminal lead extending through the at least one header opening; f) mating the first casing member with the second casing member with the first surrounding side wall contacting the second surrounding side wall, thereby forming a casing housing the anode and the cathode; and g) activating the anode and the cathode with an electrolyte provided in the casing.
