摘要：

The effect of anodic deposition potential on the supercapacitance of manganese dioxide (MnO2) and effect of surface free energy (SFE) on the supercapacitance are discussed. MnO2 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 MnO2 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 MnO2 thin films lead to high SFE and a corresponding high value of specific capacitance.
