Abstract :
This work reports the concentration-dependent electrochemical supercapacitor performance change of electrodeposited Fe2O3 thin films. Structural elucidation and morphological evolution studies are operated in the first stage and in second, electrochemical supercapacitive performances are investigated. The maximum specific capacitance of 540 F/g at 2.5 A/g in 1 M KOH is obtained. The electric parameters including specific energy, specific power and coulomb efficiency are measured using charge/discharge technique and finally, electrochemical impedance measurement is examined for knowing the internal charge transfer resistance. An equivalent circuit associated with the cell, with required parameters, is also designed.
