Title:
CARBON NANOTUBE DISPERSED LIQUID, CARBON NANOTUBE DISPERSED COMPOSITION, SLURRY FOR ELECTRODE MEMBRANES, ELECTRODE MEMBRANE AND SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2022/138496
Kind Code:
A1
Abstract:
A carbon nanotube dispersed liquid which contains: carbon nanotubes; a first polymer which contains at least one structural unit that is selected from the group consisting of a hydroxyl group-containing structural unit and a heterocyclic ring-containing structural unit, while containing no nitril group-containing structural unit; a second polymer that contains a nitril group-containing structural unit; and a solvent. With respect to this carbon nanotube dispersed liquid, the carbon nanotubes includes at least two kinds of carbon nanotubes that have different fiber diameter distributions within the range of 100 nm or less as determined by a scanning electronic microscope; and the two kinds of carbon nanotubes contain a component having a first fiber diameter distribution and another component having a second fiber diameter distribution.
