PENGARUH VARIASI AKTIVASI KOH PADA ELEKTRODA KARBON DARI TEMPURUNG KELAPA TERHADAP SIFAT FISIS SUPERKAPASITOR

Abstract

Production of carbon electrode supercapacitor made from coconut shell carbon has been demonstrated. Increment of porosity parametry was developed by KOH activation variations. Measurement of the physical properties of carbon powder carried by Scanning Electron Microscopy, X-ray diffraction for the structure of crystallinity, and energy X-ray dispersive for the content of the element. Results of Scanning Electron Microscopy characterization for KTK 3 was lighter than the KTK 1 sample. XRD characterization results for KTK 1 sample and KTK 3 sample have an amorphous structure. The percentage of carbon content was 92.82% for KTK 1 sample and 90.23% for the KTK 3 sample. The results indicated that the physical properties of supercapacitor electrode was strongly influenced by the concentration of the activator
