The carbon nanotubes according to the present invention can provide higher conductivity by allowing the BET and crystal size to satisfy the conditions expressed by formula 1 below, and consequently, can improve the conductivity of a carbon composite material containing the carbon nanotubes.&#xd7;[Specific surface area of CNT (cm/g)]&#x3e;80&#x2003;&#x2003;[Formula 1]

Highly conductive carbon nanotubes and method for manufacturing same

The present disclosure relates to a carbon nanotube dispersion including entangled-type carbon nanotubes, a dispersion medium, and partially hydrogenated nitrile rubber having a residual double bond (RDB) value of 0.5% by weight to 40% by weight calculated according to the following Mathematical Formula 1, wherein dispersed particle diameters of the carbon nanotubes have particle size distribution Dof 2 &#x3bc;m to 5 &#x3bc;m, a method for preparing the same, and methods for preparing electrode slurry and an electrode using the same.

Carbon nanotube dispersion liquid and manufacturing method thereof

The carbon nanotube pellets according to the present invention are produced by using only a small amount of solvent and have increased apparent density. The present invention can improve the problems of the change of the content generated by scattering of powders and safety issues by using carbon nanotubes in the form of pellet rather than carbon nanotubes in the form of powder in composite materials. And since the density of the pellet form is higher than that of the powder form, transport, transfer and improvement become easier. Therefore, it can be more effectively applied to the manufacturing of composite materials.

Carbon nanotube pellets and method for manufacturing same

The present disclosure relates to a carbon nanotube dispersion liquid comprising bundle-type carbon nanotubes; a dispersion medium; and a polyvinyl butyral resin having a weight average molecular weight of greater than 50,000, a method for preparing the same, methods for preparing electrode slurry and an electrode using the same, and an electrode and a secondary battery prepared using the carbon nanotube dispersion liquid.

Carbon nanotube dispersion and method for producing same

The present disclosure relates to a carbon nanotube dispersion including carbon nanotubes, a dispersion medium, and partially hydrogenated nitrile rubber having a residual double bond (RDB) value of 0.5% by weight to 40% by weight calculated according to Mathematical Formula 1, a method for preparing the same, and methods for preparing electrode slurry and an electrode using the same.
