Pembuatan elektroda karbon aktif dari biomassa kulit bawang merah (allium cep…

The global energy crisis due to limited fossil fuels and increasing energy needs has led to the development of sustainable energy storage systems. Supercapacitors are one of the promising solutions because they have high capacitance, high power density, and cycle stability. In this study, red onion skin waste (Allium Cepa L.) was utilized as an activated carbon electrode through pre-carbonizati…
