Elektroda Karbon Aktif Dari Biomassa Pelepah Daun Pinang Dengan Variasi Konse…

Supercapacitors are renewable energy storage devices consisting of electrodes, electrolytes, current collectors, and separators. In this study, carbon electrodes were made from areca leaf midrib biomass waste with variations by activation using KOH by various concentrations of 0.1 M, 0.2 M and 0.3 M, with the sample codes being PDP-01, PDP-02, PDP-03. The fabrication of carbon electrodes b…
