US Classification:

204 561

Abstract:

The shelf life of electrochemically prepared AgO cathodes is improved by reasing the temperature of anodization step to about 70. degree. C. or higher. At these elevated temperatures the capacity of the AgO electrode can also be increased by using a charge-discharge-charge regime.
