Abstract
Growing environmental factors like depletion of fossil fuels have given room to alternative energy technologies. Recently, attention has been focused on the development of the electrochemical capacitors with high power, which are called super capacitors for energy storage. Considering different materials and its oxides so far, ruthenium oxide, Magnesium oxide, Molybdenum sulfide, Molybdenum Oxides, Nickel Oxide has been investigated. Molybdenum oxides and sulfides have given more importance over all other materials because of its low cost, great quantity and very high capacity. Manganese oxides can exhibit various structures but it depends mainly on the methods of synthesis and post treatment procedures. Electrochemical deposition is most preferred because other methods are very expensive, due to high temperature and vacuum technology. The purpose of this study is to understand the thin film deposition mechanism of molybdenum disulfide, and to find the thickness of deposition on flat glassy carbon electrode. Most of the research studies show the capacitance of the thin film deposition on three-dimensional electrodes made from Nano particles, carbon foam, and other porous electrode materials report the charge storage capacity in units of F/g rather than F/cm2 .In this study an effort is made to understand the thin film deposition of MoS2 ( molybdenum disulfide) on flat materials like glassy carbon electrode, ITO , and gold in order to determine the fundamental basis for capacitance values reported in these different units and it was found that the MoS2 deposited on GCE has consistent capacitance about 0.009 F/cm2 after annealing the deposits
