Synopsis

Electrodeposition techniques is used for the deposition of nickel oxide thin film electrodes. In the present work, we report electrodeposition of nickel oxide thin film on the conducting stainless steel (SS) substrates for the application of electrochemical supercapacitor. X-ray diffraction confirms simple cubic crystal structure with polycrystalline nature of the deposited NiO sample that exhibits hydrophilic nature confirmed from the wettability study. The Scanning Electron Microscope (SEM) observed dense with cracky morphology. UV spectrum exhibits 3.55eV band gap of samples. The capacitive characteristics of the deposited thin film are investigated in 1M KOH electrolyte using cyclic voltammetry (CV). The supercapacitive properties of NiO are strongly affected by the scan rate. The maximum specific capacitance obtained is 162 F/g at 2 mV/s scan rate.
