The present disclosure, in one embodiment, relates to a dispersant for an electricity storage device electrode, which contains a repeating unit represented by general formula (1), and in general formula (1), the molar fractions when a, b, and c each represent a + b + c = 1 satisfy the relational expressions 0.50 < b + c < = 1.00 and 0.50 < = b/(b + c) < = 0.95. And R4 is preferably the branched alkyl group. R5 is preferably an alkyl group having 1-12 carbon atoms, a saturated hydrocarbon group having 1-12 carbon atoms and including an alicyclic hydrocarbon group, or a saturated hydrocarbon group having 1-12 carbon atoms and having a hydroxyl group. [chemical] # imgabs0 # 本公开在一个方式中涉及一种蓄电设备电极用分散剂，其包含以下述通式(1)表示的重复单元，下述通式(1)中的a、b、c各自为a+b+c＝1时的摩尔分数，满足0.50＜b+c≤1.00及0.50≤b/(b+c)≤0.95的关系式。R4优选为支链状的所述烷基。R5优选为碳数为1以上且12以下的烷基、包含脂环式烃基的碳数为1以上且12以下的饱和烃基、或具有羟基的碳数为1以上且12以下的饱和烃基。[化1]#imgabs0#
