Development of the cathode materials for lithium-sulfur batteries is vital to meet the demand of the portabledevices, power tools, future usage of electric vehicles etc..Sulfur is a promising inexpensive cathode material with a highenergy density, environmental acceptability and also are more abundant in nature. Lithium–sulfur batteries possess a highertheoretical capacity of 1672 mAh g-1than the commercial Lithium Ion batteries. In spite of these advantages, dissolution ofthe intermediate polysulfides is hindered the realization of the lithium-sulfur batteries. A simple solid state reaction methodhas been tried for the preparation of the SMN cathode material by varying the proportion of MnO2 and sulfur. The effect ofMnO2 in the as prepared composites electrodes on their physical and morphological properties were investigated. In XRD,the peak intensity of sulfur gradually decreases with the increasing content of MnO2.The present results suggest that theSMN73 composite is a good candidate for the cathode of Li-S battery.
