ABSTRACT:
A closed gas-tight battery comprised of cells having electrodes, separators and electrolyte, each cell having its own housing which is open at one face and constituted of a circumferential plastic wall forming a sealing element in conjunction with a disk-shaped conductive face wall. The face wall is mounted at its peripheral rim in the one end portion of the circumferential wall, in gas and liquid-tight fashion. An end of the circumferential wall is flush, at the open end of the cell housing, with the plane of an adjoining cell component, while the other housing end lies in one plane with the outside surface of the conductive wall of the cell. Each cell forms a separate unit, and a stack of such units is sheathed by the battery casing to be sealed gas-tight.
