Title:
CARBON NANOTUBE DISPERSION, SLURRY FOR SECONDARY BATTERY ELECTRODE, METHOD FOR PRODUCING SLURRY FOR SECONDARY BATTERY ELECTRODE, SECONDARY BATTERY ELECTRODE, AND SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/181869
Kind Code:
A1
Abstract:
Provided is a carbon nanotube dispersion containing carbon nanotubes, a binder, and a dispersion medium. The binder includes a polymer (A) containing an aromatic vinyl monomer unit and a linear alkylene structural unit having four or more carbon atoms. The proportion of the binder in the carbon nanotube dispersion is 30 mass% or less, and the percent change in the viscosity of the carbon nanotube dispersion under predetermined conditions before and after leaving the carbon nanotube dispersion to sit for one week is 50-300%.
