The development and operating characterisitics of the PS132 thermal battery are described. The PS132 uses the electrochemical system CaLiCl-KCl eutectic-SiO2CaCrO4, and it is one of the smallest batteries of its type ever built that can meet its electrical and envronmental requirements. A development program that included construction of approximately 400 PS132-like batteries showed that obtaining acceptable DEB electrolyte-cathode powders was a major problem. Most commercial DEB powders caused excessive amounts of CaLi2 molten metal to form in teh operating thermal cells of the PS132. This molten metal then flowed from the cells and caused electrical short circuits.
