Abstract
This work focuses on studying the effect of Sodium Dodecyl Sulphate (SDS) at its critical micelle concentration (CMC) on the performance of ion conducting gel polymer electrolytes (GPEs) for supercapacitors. By incorporating SDS at its CMC, the morphology of GPE were altered, leading to improved ion transport properties. Additionally, SDS influenced the electrode-electrolyte interface, resulting in modifications to the charge storage mechanisms and capacitance values. The GPE exhibited a high ionic conductivity of 5.6 mS/cm. The resulting supercapacitor demonstrated exceptional performance with respect to the blank supercapacitor, including high specific capacitance, energy density, as well as low self-discharge characteristics. The specific capacitance of the supercapacitor was measured to be 18.01 Fg-1, while the energy density reached 0.362 Wh/kg. Furthermore, the supercapacitor exhibited a power density of 2.00 kW/kg. The electrolyte was analysed using impedance studies to study the effects of SDS micelles on the properties of the electrolyte film. The GPE was sandwiched between two Laser Induced Graphene (LIG) electrodes prepared from (Polyimide) PI Sheets. Cyclic Voltammetry (CV), Galvanostatic Charge-discharge (GCD), and Electrochemical Impedance Spectroscopy (EIS) was done to study the electrochemical characteristics of the supercapacitors.
