Abstract: A bipolar battery is provided which comprises at least two battery cells, said battery cells each comprising a plurality of electrodes, said electrodes comprising at least two cellular end plate electrodes and at least two interstitially located single pole electrodes, a continuous, sheet-like insulator located in alternating, woven disposition within each of said cells between all adjacent electrodes to provide electrical separation thereof, wherein the end plate electrodes of adjacent cells are of opposite polarity and comprise a single, bipolar electrode, and all of said electrodes are adapted to conduct current internally between each other and said cells.

Abstract: The invention disclosed is a floating metal/air battery wherein the anode is immersed in an electrolyte, and the cathode is exposed to the atmosphere. An electro-conductive path between the anode and cathode is achieved by a wick means in contact with the electrolyte. Embodiments are described for use in sea-water and in fresh water.
