A Compact and Long Life Power Source for Advanced Munitions

A reliable 20-year shelf life power source is needed to activate advanced smaller munitions. Most of the current batteries and other power sources do not have such a long shelf life and reliability. The only battery chemistry proven for such a long life and reliability has been used only for very low power applications due to limited ionic conductivity of the electrolyte. Materials & Systems Research, Inc. will develop a long life battery power supply by using the proven battery chemistry for high reliability, long shelf life, and long life under continuous discharge operation. To overcome the issue of its very low current discharge limit, a new composite-based electrolyte cell design will be implemented using a high ionic conductivity material. Small coin cells and a prototype battery cell will be assembled and tested in Phase-I.
