Recently, low cost and environmental friendly energy storage devices has received much attention for a portable electronics and electric vehicles. In search of economical and environmental being materials, lignin is found to be the most promising candidate because of high carbon content, biodegradability, antioxidant activity and favorable functionality. These advantages have motivated us in developing all lignin-based energy storage device. Here, we have prepared lignin incorporated PAN nanofiber as porous electrode material and lignin based hydrogel electrolyte by crosslinking it with chemical crosslinker. We have fabricated all-solid-state flexible supercapacitor by integrating the lignin-PAN nanofiber electrode and crosslinked lignin based hydrogel electrolyte. Structural analysis of electrode and electrolyte was carried out by IR, SEM, XRD, BET and Raman spectroscopy. Also, electrochemical performance of electrolyte and flexible supercapacitor was measured by LSV, EIS, CV and GCD. |
