ABSTRACT:
The invention relates to a spring for maintaining a low internal resistance in a cell employing a consumable electrode, the cell employing such a spring and the method of manufacturing a cell employing such a spring. The spring fits within one electrode and its expansion keeps the cell electrodes close together as one is depleted. The spring has turned-in edges which enable it to be wrapped about and held by a split mandrel. A cell electrode can then be wrapped about the spring and the composite inserted into the cell container. The spring and electrode can be pushed off of the mandrel releasing the spring and forcing the electrode material into close contact with a separator and second electrode.
