Abstract
A type of electrochemical cell has two electrode structure elements wound in a coil and inserted in a sealed can. The electrode structures are separated by a porous insulating sheet. One electrode structure 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 and porous insulating sheets are wider than the other electrode structures, so that when the coil is inserted in the can, the substrate and the porous insulating sheet makes contact with the top and bottom internal surfaces of the can.
