Performance of Biocarbon based Electrodes for Electrochemical Capacitor
چکیده انگلیسی

We examined bio-carbon electrodes-based electrochemical capacitor. The electrodes were produced from gelam wood activated carbon. Six types of carbon electrodes in separator – electrodes assemblies were tested using galvanostatic charging – discharging (GCD) and electrochemical impedance spectroscopy (EIS) instrumentation. Eight types of aqueous solution from acid, base and salt were used as electrolytes. Three of six electrodes were prepared from carbon pelletsand others were prepared from powdered carbons. Carbon pellets were shaped and sized into electrode monoliths, and therefore those pellets were becoming binder-less. The powdered carbon were compacted along with binder and surfactant into 20 mm in diameter electrodes. The GCD and EIS measurements clearly indicated that both binderless and binderized carbon electrodes (CE) in electrochemical capacitor (EC) have 0.01 – 28 Fg-1 and 0.001 – 2.8 Fg-1 of specific capacitance, respectively. Performance tests of EC measured with EIS and GCD methods respectively have 0.001 – 0.15 F and 0.001 – 0.203 F of capacitance.
