| Abstract: | The electric properties for high specific surface area activated carbons prepared from coal under optimum conditions were evaluated as electrodes in aqueous and organic electrolytes.The corresponding charge/discharge curves at constant current,equivalent series resistance(ESR) and leakage current were determined.The results show that the coal-based activated carbons has excellent power storage performance,stable electrochemical performance and impulse properties.The specific capacitance values in aqueous and organic electrolytes are 204F/g and 158F/g.Excellent high-frequency coupling performance and small ESR are exhibited in aqueous electrolyte.This can be explained by a bimodal pore size distribution—large pores accessible to both electrolytes and small pores accessible only to the aq-ueous electrolyte. |
