CARBON NANOTUBE DISPERSION, SLURRY FOR SECONDARY BATTERY ELECTRODE, METHOD FOR PRODUCING SLURRY FOR SECONDARY BATTERY ELECTRODE, SECONDARY BATTERY ELECTRODE, AND SECONDARY BATTERY

摘要

Disclosed is a carbon nanotube dispersion liquid 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 a carbon number of at least 4. The proportion of the binder in the carbon nanotube dispersion liquid is 30 mass% or less, and the viscosity change rate of the carbon nanotube dispersion liquid as measured under predetermined conditions before and after leaving the carbon nanotube dispersion liquid for 1 week is 50 % or more and 300 % or less.
