Zinc/Silver Oxide or Silver Zinc BatteriesCommon information:Common low capacity primary button cell versions are typically called Silver Oxide batteries. They have anopen circuit voltage of 1.6 Volts. Two types of Silver Oxide batteries are available, one type with asodium hydroxide (NaOH) electrolyte and the other with a potassium hydroxide (KOH) electrolyte.Because of the high cost of sliver they are available in either very small sizes as button cells where theamount of silver used is small and not a significant contributor to the overall product costs or they areavailable in very large sizes for critical applications where the superior performance characteristics ofthe silver oxide chemistry outweigh any cost considerations.<strong>Advantages</strong>:• High energy density• Cell OCV = 1.6V , higher than alkaline cell• Low self discharge long shelf life (better than zinc air)• Better low temperature performance than zinc air• Flat discharge characteristics - flatter than alkaline battery.Disadvantages:• High cost (Silver)• Lower energy density than zinc air.• Poor low temperature performance.• Suffers from dissolving of the Zinc and the formation of Zinc dendrites which pierce the separator.• Very expensive for high power applications
