Efekvariasi Waktu Ball Milling Terhadap Karakteristik Elektrokimia Sel Superk…

Supercapacitor electrodes from rubber wood saw dust (RWSD) have been fabricated using experiment method with ball milling time variation of 20, 40, and 80 hours and thickness of 0.2 mm. Carbon electrodes were carbonized at 600oC an followed by physical activation method in CO2 gas atmosphere on the constant temperature of 900oC, and chemical activation was performed by KOH as an activating…
