Abstract
Provided are metal-air cells that each include a plurality of protruding connector members and a plurality of protruding mechanical stops. Two or more of the cells are joined to create a battery stack. Two cells are joined by heating connector members of the cells, and then forcing the cells together so that the connector members of one cell are welded or fused to connector members of the other cell. During the fusing of the connector members, the mechanical stops of the cells being joined abut one another to arrest movement of the cells toward one another. The arresting causes a plenum to be uniformly defined between the cells. The fused connector members and abutting mechanical stops cooperate to define three-dimensional truss-like system that provides structural integrity. Each of the metal-air cells have a case with an exterior. surface and an interior surface that defines a chamber that contains an anode and air cathodes. The case defines air openings that extend between the exterior surface and the interior surface for supplying air from the environment exterior to the case to the air cathodes within the chamber. Connector members and mechanical stops are preferably integrally formed with their case, interspersed with the air openings, and arranged in arrays.
