FABRICATION OF ULTRA FLEXIBLE SUPER CAPACITOR USING POLYVINYLIDENE FLUORIDE Abstract: Stretchable energy storage devices are essential component of fully stretchable and flexible electronics devices. The stretchable and flexible super-capacitors are promising candidates due to their high power density, long life, durability and safety. Super capacitors are high energy storage devices due to their ability of delivering high peak current and storing huge amount of energy in a short time with very low internal power loss. This thesis presents the fabrication and characteristics of ultra-flexible super capacitor based on VLSI technology. The super-capacitor consist of Pvdf as substrate as well as dielectric and gold as electrode. We characterized the fabricated ultra-flexible super capacitor which exhibited high capacitance using impedance analyzer. We also analyzed the charging and discharging value of the super capacitor using cyclic voltammetry. Using pvdf as both substrate and dielectric the super-capacitor is made more economical. INTRODUCTION Super-capacitors, also known as ultra-capacitors or electrochemical capacitors, utilize high surface area electrode materials and thin electrolytic dielectrics to achieve capacitances several orders of magnitude larger than conventional …show more content…

The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid. The solution is then poured uniformly into a petri dish and kept in hot air oven to get dry and sterilize. The temperature set in the hot air oven is 140 degree Celsius. As the solution gets dry, the flexible thin film substrate is obtained, which is not uniform. Fig 3 shows the flexible thin film
