The effect of physical activation temperature on physical and electrochemical properties of carbon electrode made from jengkol shell (Pithecellobium jiringa) for supercapacitor application

The effect of physical activation temperature in the preparation process of activated carbon electrode for supercapacitor application has been analyzed successfully. The activated carbon made from jengkol shell (Pithecellobium jiringa) with a combination of chemical and physical activation. The physical activation temperature varied of 800?C, 850?C, and 900?C. High specific capacitances of activated carbon electrode as high as 220F g-1 was found in physical activation temperature of 850?C. Additionally, physical properties of activated carbon also evaluated such as density, degree of crystallinity, surface morphology and chemical content. These excellent results show great potential for jengkol shell in developing energy storage devices of supercapacitor application. ? 2020 Elsevier Ltd. All rights reserved.
