The invention relates to a bipolar battery comprising: a) one or more stacks of battery plates assembled into electrochemical cells comprising: one or more bipolar plates comprising a substrate having an anode on one surface and a cathode on the opposite surface, a monopolar plate comprising a substrate having a cathode deposited on one surface, and a monopolar plate comprising a substrate having an anode deposited on one surface, wherein the battery plates are arranged such that the surfaces of the battery plates having a cathode deposited on the surface face the surface of another battery plate having an anode deposited on the surface, and the monopolar plates are located at opposite ends of each stack of battery plates; b) a liquid electrolyte disposed between each pair of battery plates, wherein the liquid electrolyte functions with an anode and cathode pair to form an electrochemical cell; c) a separator located between the anode and the cathode of the electrochemical cell; c) a membrane comprising a polymeric material disposed about an entire periphery of edges of the one or more stacks of battery plates so as to form a seal about the periphery of the edge of the plates, and wherein the seal prevents the liquid electrolyte from flowing outside of the one or more stacks of battery plates.
