A hierarchically porous rice husk-based activated carbon, which had been prepared by a combined method (carbonization, NaOH-leaching and KOH activation), has a high specific capacitance and power density as a supercapacitor electrode in aqueous or organic electrolytes. It was subjected to a simple t...
