Abstract

An electrochemical cell having a can for containing electrochemically active materials including positive and negative electrodes and electrolyte. The can has a bottom end and an open top end, and positive and negative electrodes disposed in the can. An inner metal cover is disposed in the open end of the can and has a first peripheral flange. An outer metal cover is disposed over the inner cover in the open end of the container and has a second peripheral flange juxtaposed to the first peripheral flange. A seal is disposed between the can and both the first and second peripheral flanges. The low profile seal assembly advantageously provides for reduced volume consumption thereby allowing for a greater amount of electrochemically active materials in the can.
