Abstract:
Next generation electronics need to be high performance, multifunctional, and environmentally
friendly. Here, balsa wood slice was used as a green substrate to the flexible and rechargeable
energy storage devices with excellent performance is highly desired due to the demands of potable
and wearable devices. This nature derived balsa wood by partial or full removal of lignin without
altering or disturbing the hierarchically aligned cellulosic structure is known as delignified wood
(DW). We have synthesized a ternary composite electrode comprising balsa wood, graphene oxide,
and polyaniline. The properties of the synthesized material were characterized using scanning
electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy
(FTIR), and Raman spectroscopy. Electrochemical testing revealed that BW/GO/PANI as
electrode materials contributes to high areal specific capacitance of 343 mF/cm2
at the current
density of 0.5 mA/cm2
. Utilizing this BW/GO/PANI as electrodes in a symmetric configuration
supercapacitor can result in an outstanding energy density as high as 617 m Wh/cm2
at a power
density of 7172 mW/cm2
. Therefore, this study provides a promising and efficient way for the
preparation of ideal electrode materials for high-performance flexible energy storage devices.
