Aqueous carbon nanotube dispersion, paste, cathode and anode

Abstract

A dispersion containing water, a gelling agent, and 0.3 to 2 wt. % of single-walled and/or double-walled carbon nanotubes with a weight ratio of the single-walled and/or double-walled carbon nanotubes to the gelling agent at least 0.05 and not more than 10, wherein the dispersion contains gel particles formed by agglomerates of gelling agent molecules physically bound into a weak gel network by single-walled and/or double-walled carbon nanotubes. Also disclosed a method for producing a dispersion, a method for producing cathode and anode slurries, cathode and anode slurries, and a cathode and an anode are provided. The problems of obtaining an aqueous dispersion of single-walled and/or double-walled carbon nanotubes with both high stability during storage and transportation and low viscosity under various processes of its application, and producing electrode slurries and then lithium-ion battery electrodes, are addressed.
