Abstract : A liquid NH3 battery is being developed to estimate its feasibility for short-life, reserve, primary applications. Specifications require three outputs (1.5 v at 0.5 amp, 150 v at 0.02 amp, and -30 v at 0.02 amp); activation time, less than 1 sec; life, greater than 2 min at !6.7% voltage regulation; storage and operating temperature range, -55 to 75 C; and size, less than 6 cu in. All battery sections utilize a Mg/KSCN/NH4SCN-C-metadinitrobenzene/Ag electrochemical cell and liquid NH3 activation. Various stages in the battery development are illustrated and discussed. Its capability of meeting specifications appears promising; however, much work must be done before complete batteries will have been evaluated under all environmental conditions. The principle of liquid activation was shown to be feasible over the full temperature range, and the electrical output can easily be achieved within the available space. One critical component, an electrically initiated gas generator, is still to be developed to complete the simple practical method devised for storage and transfer of liquid NH3. (Author)
