Abstract
The present disclosure provides a method of preparing an anode active material having high specific capacitance in a simple and inexpensive process without applying high temperature and high pressure conditions by synthesizing urchin-shaped goethite iron oxide (alpha-FeOOH) using an aqueous solution containing thiosulfate ions and sulfate ions, followed by heat treatment to synthesize hematite iron oxide (alpha-FeO) having a nano-sized urchin-like structure, in order to provide an anode for a pseudocapacitor that is excellent in specific capacitance.
