Abstract
A seawater battery comprises a plurality of bipolar electrodes. Each bipolar electrode includes an anode and a cathode attached to the alternate sides of a barrier. The barrier is a sheet of thin flexible plastic material. The edges of the barrier extend beyond the edges of the anode and cathode. Opposing edges of the barrier are folded against the opposing edges of the anode so as to form flanges. A suitable number of the bipolar electrodes, along with suitable endwalls and end electrodes, are assembled so that the flanges of any particular bipolar electrode overlap the flanges of an adjacent barrier. An adhesive tape is wrapped around the assembly sealing the several edges of the barriers, including the flanges, and holding the bipolar electrodes in place. Alternately, a hot melt may be used to seal some or all of the battery edges. Because the barriers are very thin, the battery is compact and economical of space. Further, it is economical to construct.
