ABSTRACT:
A fluid consuming battery and method are provided for reducing electrode doming and providing an adequate sealed closure to the battery housing. The battery includes a cell housing having first and second housing components and at least one fluid entry port through a side of the cell housing for the passage of a fluid. The battery also has a gasket disposed between the first and second housing components. A first electrode is disposed within the cell housing in electrical contact with the first housing component and a second air electrode is provided in an electrode assembly disposed within the cell housing in electrical contact with the second housing component. The electrode assembly includes a first peripheral portion that is pre-compressed relative to a middle portion. The gasket has first and second extensions that bias against interior surfaces, and the second extension is radially inwards of an angled outward recess in the can.
