| 摘 要： | Five kinds of multi-walled carbon nanotubes were prepared by CVD(Chemical Vapour Deposition) and purified under the same conditions, then were used as electrodes for super capacitors in order to compare their performance. The differences measured in terms of specific capacitance by galvanostatic cycling were presented, porosity measurements using nitrogen at 77 K made on carbon nanotubes allowd a better understanding of the electrochemical behavior of these carbon nanotubes. The experiment results show that pore diameter in the range of more than 3nm is required to maximize the capacitance in the electrolyte of 1.0 mol·L-1 LiClO4/EC+DEC(VEC∶VDEC=1∶1), and the BET surface area contributed by this extent is almost linear with the specific capacitance, in which an average value is about 0.11 F·m-2, and the specific capacitance estimated from above is very close to the value by experiment.
