英文摘要	An ultralong (1.0 mm) aligned carbon nanotube (ACNT) electrode was fabricated by a cut/paste method. The electrode retains the intrinsic properties, including robust mechanical property, high surface area, and regular pore structure, of individual nanotubes. Electrochemical properties of the ACNT electrode in an ionic liquid (IL) electrolyte were studied by cyclic voltammetry, galvanostatic charge/discharge, and ac impedance spectroscopy. The ACNT electrode achieved a specific capacitance of 27 F/g, had excellent rate capability, and a long cycle life at 60 degrees C, indicating that an ACNT electrode/IL electrolyte electrochemical double layer capacitor is promising for high temperature (60 degrees C) applications. The capacitive performance of ACNT electrode is excellent, because it possesses large pores and regular pore structures, which is revealed by N-2 adsorption and scanning electron microscopy (c) 2007 Elsevier Ltd.
