Effect of Inorganic Acid Treatment on Ultrahigh Capacitor made of Carbon Nanotubes
Source abstract
Abstract
The powder of carbon nanotubes (CNTs) and the plate electrodes of ultrahigh capacitor made of CNTs were treated by strong acid. Experimental results indicated that the ratio of amorphous carbon in the powder of CNTs was lowered, the dispersity of the powder of CNTs was advanced, and several kinds of functional group were added on the surfaces of CNTs. Moreover, the specific area of plate electrodes was increased, the aperture distribution was improved. These variations resulted in the obvious advancement of the capacity properties of ultrahigh capacitor.
