“…A welldefined faradic redox peak is observed in ZnO electrode, which indicates the possible redox reaction takes place and capacitance characteristics are mainly governed by faradic redox reactions. [30] These redox peaks obtained from intercalation and deintercalation of K + from the electrolyte into ZnO shown in following reaction. [31] ZnO + K + + e − ↔ ZnO − K ( 2 ) The specific capacitance (SC) is calculated by following relation.…”

In the present investigation, the synthesis of zinc oxide (ZnO) and Mn‐doped ZnO thin film electrodes is reported for energy storage applications through spray pyrolysis technique. As‐prepared thin films are characterized by X‐ray diffraction (XRD) and scanning electron microscopy (SEM) techniques for the crystal structural and morphological analysis, respectively. The XRD pattern shows substitution of Mn2+ in ion might have substituted Zn site without changing the hexagonal structure. The micrograph of pure ZnO thin films shows that the grains are agglomerated. The Mn‐doped ZnO thin film micrographs shows the spherical type morphology. The electrochemical study is carried for various concentrations of KOH electrolyte. The maximum specific capacitance of pristine ZnO and 5% Mn/ZnO is optimized at 3 M KOH electrolyte concentration. The pristine ZnO and M5Z electrode are exhibited 151 and 360 F g−1 maximum specific capacitance, respectively.

“…The most essential factor in energy storage is the long-term cyclic stability of the electrode [6,19]. The long-term cyclic stability and reversibility of porous GO, α-F0.05 and α-F0.05@1%GO electrodes were evaluated by repeating the CV test in the range of -1.2 to -0.3 V at a scan rate of 100 mVs -1 ; the results are shown in Fig.…”

“…In order to study the capacitive performance of Co 3 O 4 electrode, cyclic voltammetry was carried out in NaOH and KOH electrolyte in the voltage range −1.2 V to +0.4 V and −0.2 to +0.5 as shown in calculated using the literature and detail enlightenment concerning supercapacitor. [14] Cyclic voltammetry was carried out with the help of electrochemical analyzer using saturated calomel electrode as the reference electrode, a platinum wire as counter electrode and stainless steel as working electrode. From cyclic voltammetry, the calculated specific capacitance is 554 and 479.3 F g -1 at 5 mV s -1 in 1 m NaOH and 1 m KOH electrolyte.…”

Metal oxide based supercapacitors have emerged as one of the most elegant storage systems with exclusive characteristics with high power density and long‐term cycling stability. Cobalt oxide (Co3O4) has particularly obtained rising interest due to their natural abundance, environment friendly, low cost, and high specific capacitance. Co3O4 thin film electrodes were successfully deposited via a simple and easy galvanostatic electrodeposition technique on to cheap stainless steel substrate. As‐deposited thin films were heated at 500 °C for its conversion to Co3O4. These films were characterized for XRD, SEM, and CA to understand the structural, morphological and wettability properties of Co3O4 electrode. By using cyclic voltammetry, charge‐discharge study and supercapacitive behavior of Co3O4 electrode were examined. The Co3O4 electrode showed maximum specific capacitance of 554 F g–1 at 5 mV s–1 in 1 m NaOH electrolyte. The specific energy, specific power, and coulombic efficiency showed 16.32 Wh kg–1, 11.72 kW kg–1, and 94.2%, respectively. The results clearly evidenced that those devices based on Co3O4 electrodes are promising energy storage devices for microelectronic applications as well as high energy supercapacitors.
