ABSTRACT:
A type of electrochemical cell has elements wound in a coil and inserted in a sealed can. One element has a metal substrate carrying a plurality of holes. The metal substrate supports layers of an electrode material such as porous carbon. Both edges and one end of the substrate is kept free of the material. The bare end of the substrate is on the outside of the coil. The substrate is wider than other elements of the coil, so that when the coil is inserted in the can, the substrate makes contact with all the internal surfaces of the can.
