Abstract:
1. An electrochemical cell, the cell comprising: a) an anode and a cathode separated from direct physical contact with each other by a separator housed inside a casing and activatable with an electrolyte; and b) one of the anode and the cathode being electrically connected to a first terminal lead insulated from the casing by a first glass-to-metal seal comprising a first insulating glass extending to and contacting the first terminal lead and an inner surface of a first opening of a first support portion of the casing, wherein the first insulating glass has a first glass softening point, and the other of the anode and cathode being electrically connected to a second terminal lead insulated from the casing by a second glass-to-metal seal comprising a second insulating glass extending to and contacting the second terminal lead and an inner surface of a second opening of a second support portion of the casing spaced from the first support portion, wherein the second insulating glass has a second glass softening point less than the first glass softening point; and c) wherein the first and second softening points differ by more than 25° C.
