Abstract
An aspect of the present disclosure relates to a dispersant composition for an electrode of a power storage device. The dispersant composition contains an acrylic polymer (A), an amine compound (B) with a boiling point of 200° C. or less, and an organic solvent (C). The acrylic polymer (A) contains a constitutional unit a represented by the following formula (1). The compound (B) is at least one amine compound selected from the group consisting of a secondary aliphatic amine, a tertiary aliphatic amine, an aromatic amine, and a heterocyclic amine.
