Carbon nanotube, carbon nanotube dispersion and its application

摘要

Problem to be solved: to provide a carbon nanotube having a high dispersion, a carbon nanotube dispersion, a carbon nanotube resin composition and a compound slurry in order to obtain an electrode film having high adhesion and conductivity. More particularly, providing a non aqueous electrolyte secondary battery having excellent rate and cycle characteristicsCarbon nanotubes characterized by filling the following (1) to (6).(1) average outer diameterBET specific surface area is 5 to 25 nmFiber length is 150 to 400 m2 / g0.5 to 5.0 μ M (4) in the Raman spectrum, the maximum peak intensity within the range of 1560 to 1600 cmWhen the maximum peak intensity within the range of 1310 to 1350 cm-1 is D, the g / D ratio isVolume resistivity 1.0 × 10-2 to 1.5 × 10-2 Ω (6) true density1.7 to 2.1 g / ccNo selection
