Title :
Heat transfer in high-current thermal batteries
Author_Institution :

Abstract :
Heat transfer studies at the Harry Diamond Laboratories are summarized and applied to a 100 A thermal battery that will be used for vehicular propulsion. The gas atmosphere in the thermal insulation is a major factor affecting the heat transfer. The remotely piloted vehicle (RPV) thermal battery was designed to serve as a silent energy source for a propeller-driven missile that will deliver a warhead payload. The high-current capacity Li(Al)/LiCl-LiBr-LiF eutectic-MgO/FeS2 electrochemical system was chosen for the RPV battery because of the high power requirements. RPV battery test results are given. The feasibility of a 100 A thermal battery for vehicular propulsion has been demonstrated
