Aqueous supercapacitors with enhanced energy densities are much needed for their non-toxic and environmental benignity. Metal oxide based pseudocapacitors enhance the specific capacitance and energy density of the device by enlarging the potential window of aqueous electrolyte beyond 1.0 V along with faradic participation. Manganese oxide is an attractive material among the oxide materials used as electrode in supercapacitors because of its high specific capacity, non-toxicity, earth abundance and environmental compatibility. In the present work, β-MnO2 nanostructures have been electrodeposited on activated carbon paper as a binder and additive-free electrodes. Further, the effect of redox mediator in the electrolyte is assessed by fabricating ASC with various molar ratios of KI.
