Abstract

Carbon Nanotubes (CNTs) were activated by CO₂ and air under different durations, then were used in polarizable electrodes of electric double-layer capacitors (EDLCs). Experimental results indicated that air and CO₂ activation could modify intrinsic structures and improve dispersity of CNTs. Specific capacitance of EDLCs based on activated CNTs was obviously improved and the equivalent series resistance decreased, but the effects were influenced by duration of activation process.
