Manganese is one of the most abundant heavy metals in the earth's crust. With over 30 known minerals, manganese oxides have been utilized for thousands of years in ancient Greece and Egypt as a glass pigment and a steelmaking component. To achieve the engineering goals outlined above, Manganese oxide (MnO2) will be used as the electrode material due to higher specific capacitance, large potential range, and various crystal structures that can be formed within the oxide. Manganese oxide shows ultrahigh specific capacity when used as cathode material for supercapacitors. It also exhibits excellent stability and reversibility. However, these factors alone don't achieve the high engineering goals outlined. The MnO2 alone does a great job of increasing the energy density, but it comes nowhere near current lithiumion batteries and is used practically daily. Additional factors and enhancements would need to be done to get it to the level the engineering goal required. These enhancements specifically should focus on MnO2's volume expansion during the charge/discharge process, structural pulverization, and low conductivity, which restrict its applications.
