    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.
