A PRELIMINARY STUDY OF FACTORS AFFECTING MAGNESIUM DRY CELL PERFORMANCE CHARACTERISTICS,
Abstract
Preliminary investigations were carried out to determine the cell parameters that influence the 'delayed action' of 'N' size magnesium dry cells when subjected to the duty cycle and drain rate encountered in the AN/PRT-4 radio set. High concentrations (5N) of magnesium perchlorate electrolyte, protective films such as Cramolin, applied to the anode, and low concentrations of chromate ion were found to be beneficial in reducing the delayed action characteristic of the magnesium dry cell, but had a deleterious influence on the service capacity of the cell. Cells incorporating more active electrolytes such as MgCl2, LiCl and MgBr2 and various mixed perchlorates and mixed bromides were evaluated. None of these electrolytes resulted in cells that performed better than cells incorporating magnesium perchlorate electrolyte when both delayed action and service capacity were considered. There is little difference between cells made with AZ10 alloy cans and AZ21 cans with regard to service and delayed action characteristics. (Author)
