Abstract

Petroleum-based needle coke was activated by KOH to develop high-performance activated carbons as carbon electrodes for an electric double-layer capacitor (EDLC). The effect of preparation parameters on the properties of activated carbons was investigated, and their EDLC properties were measured in an organic electrolytic solution. As-prepared activated carbons (NCD-ACs) exhibit large surface areas (400-2900 m2/g), high EDLC capacitances (14-44 F/g), and low system resistances (8.3-18.7 Ω) on the basis of the anisotropic texture of their precursor.
