Abstract:

Almondshell-basedchemicallytreatedandactivated nanoporous charcoal powder (AS(T)) has been successfully prepared by chemical activation method using potassium hydroxide (KOH) as an activating agent. The as-synthesized AS(T)wassystematicallycharacterizedbyvarioustechniques like N2 adsorption, scanning electron microscopy (SEM), Xray diffraction, and thermogravimetric analysis. The AS(T)based nanoporous activated charcoal is tested as an electrode material with ionic liquid-based polymer gel electrolyte for electrochemical double-layer capacitors (EDLCs). EDLCs prepared from AS(T) exhibit specific capacitance of 986.3 mF cm−2 (equivalent to single-electrodespecific capacitance of 563.6 F g−1). The energy density of 62.8 Wh kg−1 and power density of 2.1 kW kg−1 have been observed for nanoporous AS(T)-based EDLCs.

Abstract:

Low cost with high specific capacitance and energy density is the critical and main requirement for practical supercapacitors. In the present work, nano porous activated carbon having specific surface area of 400 m2 g-1 from sugarcane waste (bagasse) has been synthesized and characterized as an electrode material for supercapacitor applications using ionic liquid based polymer gel electrolytes. The fabricated cell shows the overall specific capacitance of 372 mF cm-2 which is equivalent to single electrode specific capacitance of 248 F g-1 . The corresponding energy and power density of 16.3Wh kg-1 and 1.66 kWkg-1 were achieved for EDLCs.
