Abstract
A carbon nanotube dispersion includes multi-walled carbon nanotubes having between 0.1 and 13% by weight of iron-free catalytic remnants, the remnants including one or more iron-free metal oxide compound(s) of at least three metals selected from aluminum, vanadium, cobalt, and molybdenum. The dispersion further includes an amide-based solvent, polyvinylpyrrolidone, and an amine-based compound. The present disclosure is further related to a method for the preparation of MWCNT dispersions and their use in batteries.

A carbon nanotube dispersion comprising:
- multi-walled carbon nanotubes, comprising between 0.1 and 13% by weight of iron-free catalytic remnants, said remnants comprising one or more iron-free metal oxide compound(s) of at least three metals selected from the group consisting of aluminum, vanadium, cobalt, and molybdenum;
- an amide-based solvent comprising one or more solvents selected from the group consisting of dimethylformamide, diethylformamide, dimethylacetamide, and N-methyl-2-pyrrolidone and mixtures thereof;
- polyvinylpyrrolidone;
- and
- an amine-based compound comprising one or more compounds selected from the group consisting of an aliphatic amine, an amino acid, and an alkanolamine.
