This supplement is a progress report of a power-source development program. The purpose of this program is to determine the feasibility of developing a practical high-power output, reserve, primary battery based on a liquid-activated ammonia system. The battery under development will be composed of two 15-cell sections separated by an integrated activator-actuator mechanism and an electrolytic-solution reservoir system. Each section will be capable of developing 75 watts. The two sections will be linked electrically in parallel. The liquidactivated ammonia cell, upon which this program is based, is composed of a light active metal anode, an organic cathode, and an electrolytic solution formed from anhydrous liquid ammonia and salt. Such a cell has the theoretical capability of meeting the power requirements through a wide temperature range. The design and development of the 150-watt ammonia battery unit is being carried out in three phases. In the first phase, the technical feasibility of developing a high-energy density battery, operative over the temperature range of -54C to 74C, using magnesium-NH4SCN-meta dinitrobenzene as the electrochemical system was demonstrated.
