Pressure effects on the performance and the e.m.f. of the Mg-AgCl seawater battery

Abstract

The discharge curves of a magnesium-silver chloride seawater activated cell at different pressures were measured to examine the performance at great ocean depths. The e.m.f. measurements at increasing pressures were also carried out in order to understand the small differences in the discharge behaviour under different pressures and to get some information on the dissolution kinetics of magnesium in chloride solutions. The performance is shown at atmospheric pressure and at increased pressure and there is virtually no change in output power. It is found that Mg AZ61 is a better choice than Mg AZ31 at high pressures because of the nature of the sludge it forms. Partial molal volume changes for the magnesium oxidation reaction obtained with pure magnesium and its alloys (AZ31 and AZ61) in 0.5 M NaCl are presented and discussed.
