Abstract

A conductive material dispersion according to embodiments of the present disclosure may include a linear conductive material; an ionic cellulose polymer; and a nonionic cellulose polymer, wherein a weight ratio of the ionic cellulose polymer to the nonionic cellulose polymer is 60:1 to 4:1, and a weight average molecular weight of the ionic cellulose polymer may be greater than that of the nonionic cellulose polymer. Also disclosed is a method for preparing a conductive material dispersion, and a use of a dispersant defined by or composed of a combination of ionic cellulose polymer and non-ionic cellulose polymer for dispersing a linear conductive material in a solvent.
