Pembuatan Dan Karakterisasi Elektroda Karbon Aktif Dari Daun Kelengkeng Sebag…

This study focuses on the effect of using longan leaf waste as a supercapacitor electrode with variations in the concentration of ZnCl2 in the form of 0.3 M, 0.5 M, 0.7 M. Carbon electrodes from longan leaves were carbonized at a temperature of 600ºC followed by a physical activation process using CO2 at a temperature of 850ºC for 2.5 O'clock. The XRD characterization has a sloping peak w…
