Abstract:
1. A process for the production of solid discrete carbon nanotubes used in lithium ion batteries, comprising the steps of: a) selecting discrete carbon nanotubes of aspect ratio 10 to 500 and oxidation level 1% to 15% percent by weight to give selected carbon nanotubes; b) mixing the selected carbon nanotubes with a liquid to give a carbon nanotubes/liquid mixture; c) adding reagents to the carbon nanotubes/liquid mixture in correct balance for synthesis of a lithium salt in a new mixture; d) reacting the new mixture at a temperature to form the lithium salt while sonicating the new mixture; e) separating solid discrete carbon nanotubes, having the lithium salt attached thereon from the liquid; and f) drying the solid discrete carbon nanotubes having the lithium salt attached thereon under an inert atmosphere at sufficient temperature to obtain the solid discrete carbon nanotubes used in lithium ion batteries.
