LOW COST ORDNANCE POWER SUPPLY.
Abstract
The preliminary and prototype designs of a liquid-ammonia-activated reserve primary battery are discussed, and cost estimates for production in quantity are presented. The prototype batteries utilize: a solution of ammonium thiocyanate in liquid ammonia as the electrolyte, a magnesium anode, stainless steel collector and fiberglass separators, and a composite cathode of m-dinitrobenzene, carbon blacks, and methyl cellulose. The batteries are activated by combined linear and rotary acceleration forces that cause the electrolyte reservoir to be ruptured, driving the solution into the cell stack. They are designed to be activated in less than 0.5 second and to produce an output of 30 plus or minus 6 volts for 120 seconds at a steady current drain of 15 mA with a 15-second-duration maximum current drain of 150 mA.
