The efficiency of 3.3'-dinitrobenzophenone as a cathode material in a magne
sium/zinc based primary battery is examined. The discharge performance of t
he cell is investigated under different parametric variations such as tempe
rature, nature of electrolyte, current drain and zeolite modification. A 14
e reduction seems to be responsible for the electrochemical reaction causin
g the reduction of 3,3'-dinitrobenzophenone to the diamino derivative, incl
uding the reduction of carbonyl group.
