Potensi Daun Cincau Hijau Sebagai Elektroda Karbon Untuk Aplikasi Superkapasitor

---

Improving the electrochemical performance of supercapacitors through optimization of biomass-based activated carbon is still a challenge, especially those with 3D hierarchical pores. This study utilizes green grass jelly leaf biomass with an innovative approach as a source of 3D hierarchical porous activated carbon for supercapacitor applications. Green grass jelly leaf-based hierarchical porous carbon was synthesized with an environmentally friendly strategy through several processes namely sun drying and 110oC oven temperature, pre-carbonization, grinding, sieving, chemical impregnation of ZnCl2, pellet molding, carbonization and physical activation. The activated carbon was optimized through different physical activation temperatures (700, 800 and 900°C) and designed without any addition of adhesives. The optimized activated carbon produced the highest specific surface area of 264.668 m2/g with a high micropore content of 86.6%. Through a physical activation temperature of 800°C, a carbon content of 78.70% was obtained followed by oxygen of 4.99% and Zn of 26.45% which acted as dopping. The hierarchical porous carbon obtained produced a specific capacitance of 194 F/g at 1 A/g in 1 M H2SO4 solution. The optimum symmetric supercapacitor showed energy density and power density of 26.94 Wh/kg and 97.17 W/kg, respectively. It is shown that hierarchically porous activated carbon derived from green grass jelly leaves with N, O and Zn proved to be a promising candidate as an electrode material to improve supercapacitor performance.
