Abstract

Biomass-based hierarchical porous carbon nanospheres offer an outstanding performance of electrode materials in electrochemical energy storage device applications. However, integrating all these advantages into one fabric is still a challenge. Therefore, this study aims to develop novel biomass of Solanum torvum fruit (STF) as a hierarchical porous carbon nanosphere source for high-quality electrode material for supercapacitor applications. The STFbased carbon nanospheres were synthesized with a green, sustainable strategy through ZnCl2 impregnation, carbonization, and physical activation. Through the 0.5 M ZnCl2, it was discovered that the carbon nanosphere maintains a dense spherical structure with enriched 3D ‘‘cow tripe-like’’ hierarchical pores. The optimized carbon nanosphere yielded a high specific surface area of 1176.29 m2 g1 with a nearly balanced combination of the micro-mesopores. The combination of the 3D hierarchical pore structure and densely packed nanospheres gave high electrochemical properties of the symmetric supercapacitor with a delightful specific capacitance of 154 Fg1 at 1 Ag1 in the H2SO4 electrolyte and high cyclic performance with coulombic efficiency 84.5%. The energy density was boosted to 30.4 Whkg1 in power density of 1.27 kWkg1 5 Ag1 . Therefore, porous carbon nanospheres from novel STF biomass are ideal candidates as electrode materials for high-performance electrochemical energy storage devices.
