Reducing Low Cost Competent Munition (LCCM) Thermal Battery Volumes by Factors of 2 to 3 and Extending LCCM Thermal Lifetimes by Factors of 10 to 20 or More: Part 1

Abstract

Munitions thermal battery electrochemical cells typically operate at temperatures of 400 to 600 C and their lifetimes are typically limited by a lack of temperature control. Possible methods of removal of high thermal conductivity H2 gas from their operating atmospheres that could prolong their lifetimes by factors ranging from 1.5 to 3 are discussed and demonstrated in this Part 1 report. A recently conceived temperature control method that should be applicable to most munitions thermal batteries might easily prolong their present thermal lifetimes by factors of 10 to 20 or more. That new temperature control method is under investigation and will be discussed in a subsequent Part 2 report.
