Title:
CARBON NANOTUBE DISPERSION LIQUID AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP2020019705
Kind Code:
A
Abstract:
To provide a carbon nanotube dispersion liquid in which carbon nanotubes are uniformly dispersed in a dispersion medium and a method for producing the same and to provide a method for producing an electrode slurry and an electrode using the same.SOLUTION: There is provided a carbon nanotube dispersion liquid which contains bundle-type carbon nanotubes, a dispersion medium and a partially hydrogenated nitrile rubber having a residual double bond (RDB) value of 0.5 to 40 wt.% as calculated by the following mathematical expression 1, in which the dispersed particle diameters of the carbon nanotubes have a particle size distribution Dof 3 to 10 μm. [Mathematical expression 1] RDB (wt.%)=BD wt./(Bd wt.+HBD wt.)×100 (in the mathematical expression 1, BD represents a structural unit derived from a conjugated diene and HBD represents a structural unit derived from a hydrogenated conjugated diene, respectively.)SELECTED DRAWING: None
