Low-cost renewable lignin is used as a precursor to produce high surface area, graphitized porous carbons for supercapacitor applications. Molecular weight and oxygen consumption during carbonization are critical factors in controlling the structure and, consequently, capacitor performance. The carbonized residues exhibit good electrochemical performance in terms of high specific capacitance, high energy density and power, and good capacity retention.
