Abstract

An aspect of the present disclosure relates to a dispersant for an electrode of a power storage device. The dispersant contains a repeating unit represented by the following general formula (1), where a, b, and c each represent a mole fraction, provided that a+b+c=1, and b and c satisfy the relationship expressed by 0.50<b+c≤1.00 and 0.50≤b/b+c)≤0.95. R4 is preferably a branched alkyl group. R5 is preferably an alkyl group with 1 to 12 carbon atoms, a saturated hydrocarbon group with 1 to 12 carbon atoms that includes an alicyclic hydrocarbon group, or a saturated hydrocarbon group with 1 to 12 carbon atoms that has a hydroxyl group.
