ELEKTRODA KARBON DARI PELEPAH KURMA (Phoenix dactylifera) MENGGUNAKAN AKTIVASI FISIKA UNTUK APLIKASI SEL SUPERKAPASITOR

Abstract

This research deals with carbon electrodes made from date palm midrib biomass by varying physical activation temperatures of 700°C, 800°C, and 900°C with sample codes PK-700, PK-800, and PK-900. Electrodes are made with several stages such as pre-carbonization, chemical activation with KOH activators, carbonization at 600 °C with N2 and physical activation with CO2. The highest density value was found in the PK-800 sample with a large shrinkage of 33.97%.
