Abstract

Abstrak. Reduced Graphene Oxide (RGO) memiliki potensi aplikasi sebagai elektroda superkapasitor. Dalam penelitian ini dikaji karakteristik charge-discharge dari sistem superkapasitor RGO yang menggunakan larutan KCl sebagai elektrolit. Film tipis Graphene Oxide (GO) dibuat dengan teknik solution casting di atas substrat glass/ITO dari dispersi GO dalam akuades dengan konsentrasi 1 mg/ml. Untuk mendapatkan film RGO maka film GO yang telah dibuat direduksi secara termal di atas hotplate pada suhu 200C selama 1 jam untuk mengurangi kadar oksigen pada film tersebut. Model superkapasitor terdiri dari pasangan film RGO/ITO sebagai elektroda, serta larutan I M KCl sebagai elektrolit. Untuk melihat karakteristik dari model divais superkapasitor tersebut dilakukan pengujian charge-discharge pada berbagai macam arus discharge. Abstract. Reduced Graphene Oxide (RGO) has potential application as a supercapacitor electrode. We studied charge-discharge characteristic of RGO supercapacitor using KCl solution as electrolyte. Thin film of Graphene Oxide (GO) was prepared using solution casting technique on glass/ITO substrate from 1 mg/ml GO dispersed in water. RGO thin film was obtained from GO film that was thermally reduced on a hotplate at temperature of 200C for 1 hour to remove its oxygen contained. Supercapacitor device model was consist of pair of RGO/ITO films as electrodes, and 1 M KCl solution as electrolyte. In order to measure characteristic of the supercapacitor device model, we performed charge-discharge measurements at varied discharge current.
