Bagasse-Lignin/Polyacrylonitrile based Carbon Fiber Fabric as Self-Doping Electrode for Supercapacitor

Abstract
Self-doping carbon fiber (CF) electrodes were prepared from bagasse-extracted lignin (BG-lignin) and polyacrylonitrile (PAN) fiber precursors. Initially, the BG-lignin/ PAN fibers were obtained via electrospinning using a weight ratio of 10 (BG-lignin): 6 (PAN) parts per hundred volume (phv) in dimethylformamide (DMF) solution. The fiber fabrics were then thermally stabilized without any crosslinking agent and carbonized at 900, 1000, and 1200oC. The BG-lignin/PAN CFs exhibited large surface area along with highly microporous structure. From the electrochemical results, the BG-lignin/PAN CF electrode carbonized at 1000°C provided the highest specific capacitance (Cs) of  107 F•g-1 at a scan rate of 5 mV•s-1 together with the highest energy and power densities of  22.03 W•h kg-1 and 325 W•kg-1, respectively, at a current density of 0.5 A•g-1. Furthermore, it showed excellent long-term-cycling stability over 5000 cycles with 100% capacitance retention. Keywords - Bagasse-lignin, Carbon Fiber, Electrospinning, Supercapacitor
