The U.S. Army is seeking a technical innovation to thermal batteries with significant improvements on specific energy and operation life for weapon systems. One-time-thermal activation batteries have advantages compared with other types of reserved batteries in terms of long reserve-time, high reliability, maintenance free, high specific power, wide application temperatures, and good mechanical properties. The low voltage cathode and thermal life limit improvement on energy density and operational time of thermal batteries. US Nanocorp, Inc (USN) proposes a new high voltage nanostructured composite metal oxide and a new compatible electrolyte with a low melting point to address Army’s request on performance improvements of the current state-of-the-art thermal batteries. Coupled with LiSi/LiAl anode, the new nanostructured composite metal oxide cathode will operate at 3V and have higher specific capacity compared with the current FeS2 cathode working at 1.7V. The application of the new cathode will increase the energy density 100%. The new electrolyte with a melting point <250oC and good chemical compatibility with high voltage cathode, will increase the active working time of the thermal batteries by increasing their thermal life (10X). The increment on active working life will also increase the energy density and reduce the battery’s surface temperature.
