Elektroda Karbon Dari Biomassa Ampas Biji Kopi Dengan Variasi Konsentrasi Znc…

Lignocellulosic-based biomass is widely used as the basic material for making supercapacitor cell carbon electrodes, because it can be produced repeatedly which is economical and environmentally friendly. In this research, carbon electrodes were made from a coffee bean waste biomass (ABK) by optimizing the chemical activation process. The process of making this supercapacitor cell electrode is …
