Abstract
A carbon nanotube dispersion including a carbon nanotube, a solvent, and a dispersant. A highly conductive electrode membrane can be produced as a result of the carbon nanotube using a carbon nanotube dispersion satisfying (1), (2), and (3). (1) An average outer diameter is more than 3 nm and less than 10 nm. (2) A peak is present in a powder X-ray diffraction analysis at a diffraction angle of 2θ=25°±2°, and a half value width of the peak is 3° to 6°. (3) When a maximum peak intensity within the range of 1,560 to 1,600 cmin a Raman spectrum is G and a maximum peak intensity within the range of 1,310 to 1,350 cmis D, a G/D ratio is 0.5 to 4.5.
