Sengon wood (Paraserianthes falcataria (L.) Nielsen) carbon as supporting material for electrochemical double layer capasitor

Abstract

A microstructure carbon electrodes was potentially developed into energy storage device, i.e electrochemical double layer capacitor (EDLC) or super capacitor. The structure has a large surface that able to increased the capacitance of electrodes. Sengon Wood Carbon (SWC) was one of microstructure carbon which mainly has honeycomb structure. SWC was prepared hydrothermally along with microwave heating. SWC has 202 m2g-1 of surface area, 14,4 S.cm-1 of conductivity and crystalline carbon peak at 29.55° with honeycomb structure. Mixtures of honeycomb sengon carbon and graphite were casted it into thin layer electrode (TLE). The electrodes are fabricated into EDLC along with aluminum foil, and their performance are tested by using Galvanostatic and capacitance meter. TLE had 2.984 to 3.547 μF/g of capacitance, initial voltage of EDLC ranged from 0.67 to 0.42 V. Capacitance of 3 cm x 4 cm EDLC ranged from 30.6 to 60 μF. Galvanostatic Charge-Discharge (GCD) indicated that SWC suitable for EDLC application.
