Flexible Light-Weight Super-Capacitors are of prime importance to the next wave of flexible electronics. Recently, Hybrid structures have been able to show promising improvements in super capacitor device operations. Vo2 has shown to be a viable option for the next generation. In the research, VO2 has been coupled with PVDF, and pyrrole to be deposited by Dr. Blade’s method. VO2 is known for its metal to insulator transitions but is also explored for super capacitor applications utilizing Dr. Blade and Electrochemical deposition. Two separate substrates have been utilized such as aluminum foil and PET/ITO because of flexibility and good electrical conductivity. Annealing temperature dependent XRD study was done to observe any type of change in crystal structure of the VO2. The surface characterization was done by Field Emission Scanning Electron Microscope shows that, the composite structure is porous in nature with small grains to provide large surface area. The thickness of the composite electrode is few hundred of nanometer obtained by profilometer . The performance of the device was measured with voltages -1.0 to 0.04V by Cyclic Voltammetry.
