BINDER-FREE FLEXIBLE SUPERCAPACITOR ELECTRODES BASED ON 1-DECANOL-ASSISTED POLYANILINENANOFIBERS

A flexible electrode with high electrochemical performance is crucial for powering next-generation flexible electronic devices. In this study, a 1-decanol-assisted polyaniline Nano fibers coated flexible electrode was developed for super capacitor applications. The Polyaniline-Decanol-Sulfate Salt (PANI-DSS) electrode demonstrated a high specific capacitance of 264 F g⁻¹ at a current of 1 mA, along with a maximum energy density of 36.6 Wh kg⁻¹. Furthermore, a flexible supercapacitor device with an active area of 100cm² was assembled to evaluate the practical performance of the electrode. The device exhibited an initial specific capacitance of 107 F g⁻¹ at a current of 2 mA. A cycling stability test over 1000 charge–discharge cycles revealed capacitance retention of 52%, indicating good electrochemical durability.
