DISPERSANT FOR RESIN COLLECTORS, MATERIAL FOR RESIN COLLECTORS, AND RESIN COLLECTOR

An object of the present invention is to provide a dispersant for a resin current collector which can uniformly disperse a conductive filler to attain sufficient charge and discharge characteristics without impairing the output power per unit weight of a battery enhanced by a reduction in the weight of a resin current collector as a feature of the resin current collector, a material for a resin current collector, and a resin current collector. The present invention provides a dispersant for a resin current collector comprising a polymer having a resin-philic block (A1) and a conductive filler-philic block (A2), wherein the resin-philic block (A1) is a polymer block composed of an olefin (a1) having 2 to 30 carbon atoms as an essential constituent monomer and a functional group contained in the conductive filler-philic block (A2) is at least one selected from the group consisting of a carboxyl group, a 1,3-dioxo-2-oxapropylene group, an ester group, a cyano group, a hydroxyl group, an amino group, an amide group, and an imide group, or the polymer having the resin-philic block (A1) and the conductive filler-philic block (A2) is a ring-opening polymerization type polyester, a dehydration condensation type polyester, or a polycarbonate.
