Abstract : A research program is being conducted to define and eliminate those problems at the Cl2 electrode which prevent the Li-Cl2 battery from operating as a practical and reliable missile energy source. A gas analysis system was developed and calibrated specifically for the gas mixtures used in studying the effect of impurities on the performance of Cl2 electrodes. The method of obtaining Cl2 electrode data was improved by the development of a more responsive sensing system. Some preliminary Cl2 electrode performance data were obtained at 1 atm. Two different laboratory high power density cells have been designed and built. The cylindrical cell has been pressure checked in its pressure container. The high pressure Cl2 and Ar gas facility has been pressure checked and operated with a simulated cell up to 10 atm. Experimental difficulties were encountered in the facility due to Cl2 condensation at room temperature. A conceptual design of a Li-Cl2 primary battery for operation in a zero-g environment has been completed. A base-line design was sized for a mission time of 30 min and a power level of 10 kw sub e. For the performance characteristics, a 30-v output and a 20-w/sq cm power density were assumed. Using this design as a base line, battery systems were sized (weights and volumes calculated) for mission times ranging from 10 to 30 min.
