NEW CATHODE-ANODE COUPLES USING NONAQUEOUS ELECTROLYTES
Abstract
New anode-cathode couples using nonaqueous solvents were investigated for use as secondary batteries for power sources in orbiting satellites. Reversibility of anode and cathode reactions in nonaqueous media was studied by measuring the current efficiency for metal deposition or dissolution as a function of current density. At densities of 20 ma/sq cm, Mg from a Mg ethyl bromide-ethyl ether solution, K from a POCl3-KI system, Al from an AlCl2-n hexylamine-ethyl ether system showed low reversibility. High current efficiences were found for Li electrodeposition from a propylene carbonate Li salt system and for an AlCl3-ethyl pyridinium bromide-toluene system at 20 ma/sq cm current density. After anodic oxidation of many metals, NiCl2 and AgCl were insoluble in the propylene carbonate system; NiCl2 was insoluble in the AlCl3-ethyl pyridinium bromide-toluene solution. (Author)
