Abstract: The galvanic battery of the present invention supplies the anode and/or cathode from an elongated strip of flexible tape preferably interconnected through a strip of inactive material functioning as a leader for said tape and for separating the tape entering the electrochemically active compartment of the battery housing from spent tape exiting the electrochemically active compartment. The battery is preferably constructed to include a supply reel having a rotatable core upon which said strip of tape is wound in a cylindrical configuration with the inner winding of tape extending from said core and being threaded through said electrochemically active compartment before being connected back into the electrochemically inactive compartment and wound as the outer winding around the core of the supply reel.

Abstract: The battery includes an anode and cathode structure spaced a fixed distance apart, a movable conveyor having electrolyte impregnated therein and means for advancing the conveyor to engage the anode and/or cathode at the anode and/or cathode interface with electrolyte. In the preferred arrangement the moving conveyor containing the electrolyte is progressively advanced through the interface spacing between the anode and cathode while the interface spacing is maintained substantially constant even as the anode is consumed. Battery operation is terminated by separating the engaging surfaces of the anode and/or cathode from the moving conveyor and is reestablished by reengaging the anode and/or cathode surfaces with the moving conveyor.
