Alkaline (Alkaline Manganese Dioxide) cont..Applications:• Low cost applications• Toys• Remote control• Flashlights• ClocksSuperCapacitor impact:• Due to low OCV it can’t to supply 2.2-2.8 V for devices including microprocessor. It requires to put DC-DC converter in order to increase voltage of battery from 1.5V to 2.8V, it requires higher pulse currentfrom battery. This type of battery doesn’t have ability to support high current pulses, due to low capacityand high leakage. In this case SC is required to supply high current pulse in order to allowmicroprocessor to work properly and to increase battery lifetime.• Due to poor performance in low temperatures environment of Lechlanche Dry Cells, SC is required tosupply high current pulses. The algorithm is simple, battery will charge SC in low current, and when pulsewould be required SC should deliver it due to excellent performance in low ambient temperatures.
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
