Abstract
An electrochemical cell having a serpentine-like electrode wherein electrode active material thereon is distributed for maximizing capacity and minimizing volume. The electrode active material extends along the length of the current collecting element of the electrode and terminates at a fold which defines an outer side of an outer section so that electrode active material is not positioned on this outer side where it would not be facing an opposite polarity electrode and where it may thus be generally ineffective for increasing battery capacity. The resulting savings in volume allows the thickness of the electrode active layer to be increased so that additional battery capacity may be achieved in the same battery volume.
