Bipolar battery

Claim 1

A bipolar storage battery employing a number of cells between a pair of parallel end walls and a pair of parallel side walls normal to the plane of said end walls, each of said cells formed between opposed cells walls each having a first and second face, said battery including: a removable-replaceable anode including a wall contacting side and cell facing side, said wall contacting side being coplanar and abutting the first face of said one wall, said cell facing side having an upper portion generally parallel with said wall contacting side and a lower tapered portion angled inwardly and downwardly forming a wedge; a cathode member contacting the second face of said other wall, said member including projections and spaces for air to act as an oxidant, and a face opposite said projections angularly disposed thereto toward said tapered portion and generally parallel with said lower tapered portions of said anode; each of said side walls including slots therethrough complimentary with the projections of said cathode member and receiving said projections, said projections extending through said wall into an adjacent cell and bearing against said wall contacting side of said anode; said wedge portion of said anode gravitationally biasing said cathode against said wall; spacer means separating said anode and said cathode member in the same cell; contact means interconnecting said anodes and passing to the exterior of said bettery forming one contact; and contact means interconnecting said cathodes and passing to the exterior of said battery forming another contact.
