Tobacco leaves and cellulose acetate tubes have been successfully carbonized (HTW-C) and mixed with metal oxides (MnO<sub>2</sub> and Fe<sub>3</sub>O<sub>4</sub>) to obtain highly active materials for supercapacitors. Moreover, poly(lactic acid) (PLA) filters have been successfully dissolved in an organic solvent and mixed with the as-prepared active materials using a simple paste mixing method. In addition, flexible MnO<sub>2</sub>- and Fe<sub>3</sub>O<sub>4</sub>-mixed HTW-C/PLA electrodes (C-MnO<sub>2</sub>/PLA and C-Fe<sub>3</sub>O<sub>4</sub>/PLA) have been successfully fabricated using the drop-casting method.
