Abstract

Official abstract text for this publication.

The present invention relates to a method of preparing purified carbon nanotubes (CNTs) comprising mixing starting CNTs with an organic solvent in the presence of sonication; substantially removing the organic solvent to obtain a CNT composition; and heating the CNT composition at 200° C. or higher to obtain the purified carbon nanotubes. The present invention further relates to the purified CNTs and cohesive CNT assemblies prepared from the method described herein, and articles (e.g. capacitor, energy storage device or capacitive deionization device) comprising the purified CNTs.

First claim

Opening claim text (preview).

What is claimed is: 1. An energy storage device comprising a current collector and an electrode on one side of an insulating material or an electrolyte, and another current collector and another electrode on the other side of the insulating material or the electrolyte, wherein at least one of the electrodes and/or at least one of the current collectors comprises purified carbon nanotubes having a Raman G/D ratio of at least 50 and a BET specific surface area of 1200 m 2 /g or highe…
