Supercapacitor electrodes from coconut shell charcoal with mass variation ZnCl2 activation have been created and characterized. The method used was experiment method. Charcoal is milled 20 hours and sifted for 100 μm and chemical activation was performed by ZnCl2 as an activating agent. The comparison of ZnCl2 and carbon weight was 1:1 (A variation), 1:1.5 (B variation), and 1:2 (C variati…
