Galvanic battery with replenishable electrodes and/or electrolyte for extended battery operation
First Claim
1. A galvanic battery comprising a housing having a single electrochemically active compartment including a source of electrolyte and a single electrochemically inactive compartment with said electrochemically inactive compartment comprising a supply of anode material in the form of an elongated strip of flexible tape interconnected as an endless loop, a supply reel having a rotatable core upon which said strip of tape is wound in a cylindrical configuration to form an inner winding and an outer winding with said inner winding extending outwardly from said core and being connected back to said tape as said outer winding thereof, with the inner winding of tape extending from said core being threaded through said electrochemically active compartment before being connected back as said outer winding and means for controllably rotating said core to sequentially advance said tape through said electrochemically active compartment.

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.

- 16. A galvanic battery comprising an electrochemically active compartment containing an aqueous source of an electrolyte, a cathode and an electrochemically inactive compartment with said electrochemically inactive compartment comprising an elongated strip of flexible tape interconnected as an endless loop extending through said electrochemically active compartment in electrochemical contact with said cathode, said endless loop of flexible tape being composed of an electrochemically inactive substrate containing a solid anode, means for separating said tape into segmented sections of anode, means for advancing said strip of flexible tape through said electrochemically active compartment such that each segment of anode is advanced into said electrochemically active compartment to provide controlled periods of electrochemical activity and contact terminals for coupling said anode and cathode in said electrochemically active compartment.
