High-Rate Magnesium/Manganese-Dioxide Batteries for Field Application From -40F To 125F

摘要

The report describes the design, fabrication and testing of two different high-rate, high-energy density primary batteries employing a magnesium/magnesium-perchlorate/manganese-dioxide system. The batteries consist of the 4-pound BA-838( )/U and the 6-pound BA-839( )/U. The batteries are capable of supplying as high as 37 watt-hours/lb. for the BA-838( )/U and 45 watt-hours/lb. for the BA-839( )/U. Both batteries are capable of operating from -40F to +125F and of surviving severe dynamics. An inexpensive activator mechanism is employed that makes possible a rapid simple means for simultaneously activating all 16 cells of the battery. (Author)
