Abstract

In this present study, a nano-MnO₂/graphene based cathode was prepared and its characteristics were studied for Mg/MnO₂ primary battery applications. A modified magnesium/manganese dioxide (Mg/MnO₂) with graphene primary cell was investigated using the prepared MnO₂-graphene nanoparticles and conventional MnO₂ system. The storage capacity and energy density of the nano-MnO₂-graphene based cathode materials increased respectively, from 2.6 to 7.5 mAh g^-1 and 3.5 to 10 Wh kg^-1. The discharge time of nano-MnO₂/graphene based cathode increased to approximately 5200 s than that of conventional micron-MnO₂-based cathode. Thus, this study opens up a new approach to use MnO₂/graphene nanoparticles as a cathode material for magnesium primary batteries in future.
