Effect of Electrodeposition Potential on Surface Free Energy and Supercapacitance of MnO2 Thin Films

The effect of anodic deposition potential on the supercapacitance of manganese dioxide (MnO 2 ) and effect of surface free energy (SFE) on the supercapacitance are discussed. MnO 2 thin films have been synthesized using a potentiostatic electrodeposition method. Their structure, morphology, wettabil...

Beschreibung
Zusammenfassung:	The effect of anodic deposition potential on the supercapacitance of manganese dioxide (MnO 2 ) and effect of surface free energy (SFE) on the supercapacitance are discussed. MnO 2 thin films have been synthesized using a potentiostatic electrodeposition method. Their structure, morphology, wettability, electrochemical properties and supercapacitance are discussed. The observed specific capacitance ( C s ) of MnO 2 thin films is 127 F/g for the deposition potential at 1.20 V/Ag/AgCl. These films also show better stability for over 1000 cycles. The porous MnO 2 thin films lead to high SFE and a corresponding high value of specific capacitance.
