- Abstract
- Hong Jin - Graduate Student, Department of Agricultural & Biosystems Engineering at South Dakota State University in Brookings, SD. Biochar from DDGS, a co-product, which was produced by thermochemically processing designed for maximum bio-energy production, was collected. Different chemicals would be used to activate the biochar. The pore structure and specific surface area of the carbon samples would be characterized using N2 adsorption/desorption method. The carbon samples would be used to assemble super-capacitors, and the properties would be evaluated by electrochemical techniques including cyclic voltammetry (CV), galvanostatic charge-discharge, and electrochemical impedance spectrum (EIS). The relationship between specific capacitance and pore structure and surface area will be discussed. All in all, we will get a pathway for developing sustainable electrode materials from bio-resources, and the previous data indicate that the activated carbon progressively treated by H2O2 presents excellent charge/discharge properties (specific capacitance above 200 F g-1) at the high current density of 1.0 A g-1, and excellent rectangular shape of CV curve.
