Optimasi Pembuatan Elektroda Karbon Superkapasitor Dari Serat Sabut Kelapa Melalui Variasi Suhu Aktivasi Fisika

---

Biomass-derived porous activated carbon materials have been receiving considerable attention in energy-storage devices especially for supercapacitor due to abundant, renewable, sustainable, and cost-effective production. In this study, porous activated carbon material with monolithic form has been successfully prepared from coconut husk fiber through one-stage integrated pyrolysis and ZnCl2 impregnation. Different physical activation temperature is the main focus in this study including 750°C, 800°C, 850°C, and 900°C. The reduction of monolith dimensions such as mass, diameter, thickness and density have been reviewed as physical properties. Furthermore, the supercapacitor cells were performed with cyclic voltammetry 1 M H2SO4 aqueous electrolyte at low scan rate of 1 mVs-1 . The supercapacitor device based on the SK-800 samples exhibited highest specific capacitance of 261 Fg-1 . This sample also performed a promising performance with an energy density of 36.25 Whkg-1 and a high power density of 136.63Wkg-1. These results demonstrate that the coconut husk fiber has been a high potential to as raw material for porous activated carbon monolith through low cost, vehicle and short-time processing with high-performance supercapacitors energy storage.
Keywords: activated carbon, coconut husk fiber, electrode materials, supercapacitor.
