ABSTRACT:
A contact assembly for use in alkaline electric cells, includes a inner metal disk and an outer metal disk which engage one another coaxially when embedded in a cell end cover to form a cell anode. The inner metal disk has a neck-like cylindrical projection having an axial bore, the projection extending inwardly of the cell. One end of a collector rod within the cell is seated within the bore of the projection so as to remain in electrical contact with the inner periphery of the projection and, thus, with the anode formed by the two metal disks, in the event the anode is caused to move outwardly of the cell in response to gas pressure developed within the cell.
