Abstract

For the first time, a new carbon–carbon composite electrode material for supercapacitors is prepared by simple KOH activation ofwaste newspaper. The amorphous nature and surface morphology of the carbon composite are investigated by X-ray diffraction (XRD), N2 adsorption/desorption and scanning electron microscopy. The surface area and pore diameter are 416m2 g−1 and 5.9 nm, respectively. Electrochemical characteristics are evaluated by cyclic voltammetry (CV) and charge–discharge tests in 6.0M KOH at a 1mAcm−2 current density. The CV results reveal amaximumspecific capacitance of 180 F g−1 at a 2mVs−1 scan rate and the data explore a development of new use for waste paper into a valuable energy storage material.
