Abstract : This invention relates to electrochemical cells and more particularly to silver oxide electrodes. Accordingly an object of this invention is to provide a new method of electrochemically preparing AgO electrodes. Another object of this invention is to provide a method of increasing the shelf life of electrochemically prepared Silver oxide electrodes. A further object of this invention is to increase the energy capacity of electrochemically prepared AgO electrodes. These and other objects of this invention are achieved by proving in the process for preparing AgO cathodes by anodizing silver plaques in basic electrolytes, the improvement of performing the anodizing process at a temperature in the range of from about 70 C to just under the reflux temperature of the electrolyte.
