中文摘要	Many applications for supercapacitors have been proposed in recent years. Supercapacitors based on charge storage at the interface between a high surface area carbon nanotubes electrode and a LiClO/sub 4//PC electrolyte is assembled. The performance of the capacitor depends not only on the materials used in the cells but also on the construction of the cells. From a constant charge-discharge test, a capacitance of 60 F and ESR (equivalent series resistance) of 35 m Omega is obtained. Evaluation of capacitor performance by different techniques is also discussed. The performance of CNTs (carbon nano tubes) capacitors for high power sources used in electronic equipment are described. Values for the specific energy and specific power of 0.8 Wh middot kg/sup -1/ and 0.75 kW middot kg/sup -1/, respectively, are demonstrated for a cell with 2.5 V maximum operating voltage. A hybrid power source consisting of lithium ionic battery and 60 F supercapacitor was demonstrated to power successfully a simulated power load encountered in GSM portable communication equipment.
