Sealed Alkaline Batteries for Space Applications

The purpose of this paper is to consider the capabilities and major limitations of the nickel-cadmium, sivler-cadmium, and silver-zinc alkaline secondary battery systems. The considerations of each of these systems are based on analysis and development work currently underway. The primary mode of operation considered is an orbital or charge-discharge type cycling at various temperature and depths of discharge. A brief failure analysis resume' is also presented.
