ABSTRACT:
An improved battery cell having electrodes formed of active material adhered to a conductive substrate with active surface areas communicating along an entire edge portion with conductors thereby minimizing resistance and allowing for communication of electrical current to and from the battery at a high rate with an even discharge from the electrodes. The plurality of electrodes is then stacked or wound to a desired configuration with a porous separator separating each adjacent electrode from the other. Communication along the entire edge of the formed electrodes on the conductive substrate with a conductive edge portion of the substrate, provide for maximum current flow in and out of the battery as well as well as reducing thermal concerns in high current applications. Elongated electrical conductors best made from copper are attached to substantially the entire length of the positive and negative edge portions.
