Preparation Of A Porous Carbon Nanotube Composite Sheet And Its Possible Application In Supercapacitors

摘要

A new kind of porous carbon nanotube sheet for using as electrodes in supercapacitors was developed in this paper. The porous carbon nanotube sheet containing a certain amount of multi-wall carbon nanotubes and carbon fibers and P(VDF-HFP) were prepared by phase inversion method. Morphology of the new carbon nanotube sheet was observed with scanning electron microscope. Capacitance of the electrode made of the carbon nanotube sheet used in supercapacitor prototypes is about 95F/g when the charge/discharge current is 0.5mA.
