ABSTRACT:
A primary electrochemical cell includes a device for reactivation of the cell after long periods of storage time. The device includes a movable diaphragm embedded in the cover portion which is coupled to an ampule having retained therein the activation material. The ampule is in close proximity with the anode and cathode elements immersed in the electrolyte and upon movement of the diaphragm the ampule is caused to release the reactivation material contained therein.
