An investigation was made of the use of the FC-2 Liquid Ammonia Prototype Battery for short-life reserve primary battery applications. The completely self-contained unit, in a volume of 90 cu cm 5.5 cu in., proved capable of operating for 5 min at a nominal 28 V, 1 A. Performance was satisfactory under simulated missile environments, including shock, vibration, spin, and temperature -54 to 74C or -65 to 165F. An organic oxidant, m- dinitrobenzene mDNB, is used as the cell cathode, and the reserve activation feature is provided by storing the electrolyte solvent, anhydrous liquid ammonia, in a separate compartment of the battery case. The basic electrochemical system is MgKSCNNH4SCN-mDNB-Cstainless steel Type 302. The measured volume enersity of this model for a 5 min discharge is 54 Jcu cm 0.1 Whcu in., and weight enersity is 20 Jg 2.5 Whlb.
