Pembuatan Elektroda Karbon Sel Superkapasitor Dari Limbah Kulit Jengkol Mengg…

The activated carbon electrodes derived from jengkol shell waste has been successfully boosted the performance of supercapacitor cell. This study was conducted to analyze the effect of KOH concentrations in the carbon electrode performance. The preparation of activated carbon electrodes begins with the pre-carbonization process at a temperature of 250ºC for 2.5 hours. Pre-carbonized samples we…
