ABSTRACT: Highly reliable power supply technologies are needed for future arming and fuzing system designs. These power supplies should be able to operate after a long dormant period of up to twenty years. A novel battery power supply is proposed for this purpose. The proposed battery utilizes a solid state electrolyte which would have indefinite shelf life. High peak specific power will be possible by optimizing the design of electrolyte composition and electrode interface structure. Battery cells will be fabricated and tested in Phase I. BENEFIT: The proposed novel battery can be used as a replacement in the current strategic system or in a future system requiring a highly-reliable, long-shelf-life power supply. Commercial applications include low-volume, long-life power supplies that can be used for emergency power applications such as disaster relief and contingency back-up power in a small package.
