Disclosure of the Invention An object of the present invention is to provide a resin current collector dispersing agent capable of uniformly dispersing a conductive filler and exhibiting sufficient charge / discharge characteristics without hindering the output per unit weight of the battery due to weight reduction, A material for a resin current collector of the present invention is a resin current collector dispersing agent comprising a polymer having a proton resin block (A1) and a proton conductive filler block (A2) Wherein the proton-conductive block (A1) is a polymer block comprising an olefin (a1) having 2 to 30 carbon atoms as an essential constituent monomer and the functional group of the proton-conductive filler block (A2) is a carboxyl group, 1,3- - at least one kind selected from the group consisting of an oxepropylene group, an ester group, a cyano group, a hydroxyl group, an amino group, an amide group and an imide group, or a combination of a protonic resin block (A1) (A2) is a ring-opening polymerization type polyester, a dehydration condensation type polyester, or a polycarbonate. |
