Abstract
The present disclosure provides a nanotube dispersion that includes a dispersion medium, a polyetheralkanol amine dispersant and carbon nanotube material. The nanotube dispersion may be used in various applications, such as in the production of electrodes for secondary batteries.
Claims22
A nanotube dispersion comprising a dispersion medium, a polyetheralkanol amine dispersant comprising a compound having a structure of formula (1) and a compound having a structure of formula (2)
- wherein each R1 is a C1-C100 hydrocarbyl group;
- each R2 is an alkoxylated hydrocarbyl group having a structure
- wherein R3 is a C1-C24 hydrocarbyl group, X1, X2, X3, X4, X5, and X6 in each occurrence are independently selected from the group consisting of hydrogen, methyl and ethyl, subject to the proviso that at least one of the two X groups that are attached to the same alkoxy unit are hydrogen, p, q, and r may each independently be any integer from zero to about 100, subject to the proviso that at least one of p, q, and r is not zero;
- and each n is any integer from 1 to about 5, and a carbon nanotube material.
A slurry for a secondary battery electrode comprising an electrode active material and a nanotube dispersion comprising an aqueous dispersion medium, a polyetheralkanol amine dispersant and a carbon nanotube material.
