摘要: | Areca palm leaves derived porous carbon material as the electrode for symmetrical solid-state supercapacitors (SSCs). The areca palm leaves biomass was processed using a fast carbonization method followed by in situ chemical activation. The structures and compositions of these biomass-derived carbon materials were characterized using X-ray diffraction, Raman spectroscopy, and X-ray photoelectron spectroscopy, respectively. One of the biomass-derived porous carbon materials, AR2, was a lightweight carbon material that possessed a large surface area of 876 m(2) g(-1). Electrochemical studies revealed that AR2 possessed a high specific capacitance of 262 F g(-1) at a scan rate of 5 mV s(-1). We fabricated symmetrical SSCs featuring these carbon material as major (80 wt%) components of the electrodes and poly(vinyl alcohol)-Li2SO4 as gel polymer electrolyte. The optimal supercapacitor (SAR2) involving AR2 exhibited a specific capacitance of 132 F g(-1) at a current density of 0.5 A g(-1) and an energy density of 10.3 W h kg(-1) at a power density of 375 W kg(-1), and durability of retaining 92% of its initial capacitance after 5000 cycles-performance that is the excellent values reported for devices featuring derived from biomass. |
