Influence of Nitrogen Doping and Pre‐Carbonization on the Performance of Lignin‐Derived Activated Carbon for Supercapacitor Applications

Abstract Nanostructured carbons are widely used as active materials for supercapacitor applications owing to their high specific surface area and electrical conductivity. Biomass waste‐derived materials can be sustainably produced. In this work, highly porous activated carbon was prepared from lignin waste for supercapacitor applications, and the effects of nitrogen doping and a pre‐carbonization treatment on the final performance were …
