Magnesium/Meta-Dinitrobenzene Reserve-Type Battery for Field Application. Miniature Reserve Type Magnesium Battery for Operation from +125 F to -40 F.

摘要

The first part of the report describes the design and testing of a primary reserve type battery employing a magnesium/magnesium perchlorate/meta-dinitrobenzene system,which was hoped to yeild a power density in excess of that of the manganese dioxide system but was determined to have serious technical problems which limit its use and efficiency. The best power density obtained by the described design was 26watt-hrs/pound. The second part of the report describes the design and testing of a reserve-type miniature 2.5volt magnesium battery for powering second generation night vision devices such as goggles and crew served weapon sights. The battery occupies 0.59cubic inches,weighs 0.64ounces and yields as high as 0.75watt-hrs. It can operate in temperature ambients ranging from +125F to -40F. (Author)
