<p>An electrochemical timer or coulometer comprising an assembly of a solid electrolyte, preferably Ag7I4PO4, a silver electrode and a detector, e.g. gold, electrode, such assembly being positioned in a metal can. By crimping the upper edge of the metal can which contains the electrodes and the electrolyte, and bringing the components of the assembly into contact, while simultaneously applying high pressure to such an assembly, residual pressure is maintained on the assembly after release of such high pressure, and good electrode-electrolyte contact is ensured. This increases the charge capacity and maximum operating current of the device. The efficiency of the coulometer and its charge retention during storage is further improved by a cycling (i.e., charging and discharging) operation.</p> |
