Disclosed are a dispersion composition for an electricity storage device slurry having good dispersion stability, an electricity storage device slurry composition having good coatability and coating drying properties, and an electricity storage device using the electricity storage device slurry composition. . A dispersant composition for an electricity storage device slurry containing a component (A) and a component (B). Component (A): The carboxyl group-containing monomer unit (I) is 15 to less than 40% by weight, the monomer unit (II) represented by the formula (1) is less than 40 to 85% by weight, and the weight Polymer A having an average molecular weight of less than 500,000, component (B): a monomer unit (I) having a carboxyl group-containing monomer unit (I) of 0 to less than 15% by weight and represented by formula (1) II) is 70 to 100 wt%, the polymer B, CH 2 = CR 1 COOC n H 2n R 2 (1) (R 1 is H or CH 3; R 2 is H or OH; n = 1 to 20 Integer) [Selection] Figure 1 |
