High carbon aromatics rich and naturally abundant biopolymers, such as lignin and their derivatives, show promising future as a carbon source for energy storage applications. In recent time, electrospinning of lignin-based solutions and their carbonization in the form of nanofibers have drawn a great interest among researchers because of their high conductivity and large specific surface area. The later characteristics render them suitable for their use in energy storage devices. There are several industrial methods to extract lignin from various types of biomass, resulting in a diverse array of chemical structures and compositions. These differences can significantly influence the behavior of lignin-based solutions during the electrospinning process as well as the structure, elemental composition, and electrochemical performance of the final lignin-based carbon nanofibers. Therefore, in this study, different types of lignin, such as kraft, lignoboost, soda lignin as well as lignin extracted from bioethanol production are electrospun by using poly(vinyl alcohol) as a binder polymer. The spun fiber networks as such were directly carbonized at 1000 °C for 1 h under the nitrogen atmosphere. Images from the scanning electron microscopy show that all fibers are intact and they remain a continuous fiber network after carbonization. The carbon fibers prepared from lignoboost lignin have the highest carbon content due to the high purity of the precursor. Electrochemical measurements show that the carbon fiber network prepared from kraft lignin can reach a specific gravimetric capacitance of 241.4 F g<sup>-1</sup> in a two-electrode supercapacitor. Paper will also present electrochemical performance data as well as the effects of fiber alignment for supercapacitor applications.
