    • Abstract

       

      Wood-derived carbon is a neoteric self-supporter electrode material for supercapacitors or batteries. To improve the electrochemical characteristics, polyaniline (PANI) was deposited on wood carbon (WC) by an in-situ polymerization method. The sandwich-like symmetrical solid-state supercapacitor was developed by preparing WC/PANI composites andtheir electrochemical properties were examined. The device showed an excellent capacity retention and displayed the maximum specific capacitance of 22.5 mF cm$^{−2}$ at a scan rate of 10 mV s$^^{−1}$. It was also demonstrated an excellent electrical conductivity and an outstanding retention of $\sim$82%. It was suggested that the PANI accommodated into WC without any significant morphological change during the charge–discharge cycling of the hybrid WC-based composites. The microstructure and chemical structure of WC/PANI composites were also characterized by the Fourier-transform infrared, Ramanspectroscopy and X-ray diffraction techniques.
