Abstract

See full text

The disclosed is a method for producing a carbon material dispersion which removes efficiently and reliably metallic components from carbon materials, and that provides a carbon material dispersion of a high product quality and stable electrical properties. The method comprises a first magnetic separation step in which the powdered and/or granulated carbon material C is applied to the surface of a rotating magnetic roll 130 to remove the metallic component M from the carbon material in the dry state of the powdered and granulated carbon material C; and a second magnetic separation step in which a magnet element 310 is placed in a carbon material dispersion D, in which the carbon material from which the metallic component has been removed in the first magnetic separation step is dispersed in a dispersing medium, in advance of the second magnetic separation step.
