Description
Summary:This paper reports the results of experimental studies on a magnesium/magnesium perchlorate/N,N'-dichloro-dimethylhydantoin cell system at various temperatures ranging from 70 to -20 degree C. A constant current discharge method was employed to evaluate the battery parameters such as discharge capacity, energy density, coulombic efficiency and internal resistance. Scanning electron microscopy (SEM) was performed on post-polarized magnesium samples to follow the morphological changes in the anodic material with respect to temperatures. These investigations broadly reveal that the cell system can give rise to the open-circuit/closed-circuit voltage of > @d similar to 2.0 V and it is possible to obtain current densities of 20 mA cm super(-2) during discharge.
