Abstract
A bipolar battery includes a housing and a plurality of bipolar electrode plates aligned with respect to one another within the housing to form a cell between each pair of adjacent bipolar electrode plates. Each of the plurality of bipolar electrode plates includes an electrode substrate having a first face and a second face, an electrical connection element overlapping at least a portion of both the first face and the second face, a first carbon foam current collector on the first face of the substrate, a second carbon foam current collector on the second face of the substrate, and a chemically active paste on both the first and second carbon foam current collectors. A plurality of electrical separators are interleaved with the plurality of bipolar electrode plates.
