“…[10,11] On the other hand, pseudocapacitor utilizing transition metal oxides (such as RuO 2 , NiO 2 , MnO 2 etc.) [12][13][14] and conducting polymers like polyaniline (PANI) [15] where capacitance generates from fast faradic reaction, have been studied extensively as active electrode materials for SCs applications. [6] Among transition metal oxides, MnO 2 is considered as most attractive and potential electrode material for SCs applications due to its low cost, high natural abundance and environmental friendliness.…”
