REVIEW OF RECENTLY DEVELOPED LIQUID AMMONIA BATTERIES,

Abstract

Description, performance, and unique features of seven recently developed liquid ammonia primary reserve batteries are briefly outlined. All are liquid activated, four by the pure solvent NH3 and three by an electrolyte solution. Of the seven different cell constructions, all use Mg anodes, five have organic oxidant cathodes (metadinitrobenzene) and two inorganic (HgSO4, AgC1). Electrolyte is a neutral KSCN in six instances and an acid NH4SCN in one. Nominal peak discharge cell voltage approximates 2 V at all temperatures from -55 to +75C and at cursities from 1 to 100 mA/sq cm. Operating times range from 60 s to 72 h. Methods of activation include manual, electric, percussion, and acceleration. Activation times, except for the manual method, range from 35 ms to 3 s with no preconditioning required at any temperature. The batteries described have undergone varying degrees of laboratory and field testing but all may be regarded as operationally feasible. In 1966, at least one model should be fully documented and in limited production. (Author)
