The object of the present invention is to provide an adhesive for an electrochemical cell which has sufficient adhesion to a current collector and an active material, is electrochemically stable, is not easily swelled by an electrolyte, and can sufficiently improve cycle characteristics of a battery.nn n n In order to solve the problem, the binder for an electrochemical cell of the present invention is composed of a polyolefin copolymer (A), and the polyolefin copolymer (A) contains a structural unit derived from an olefin, and (methyl) In the structural unit derived from acrylic acid, the carboxylic acid contained in the structural unit derived from (meth)acrylic acid is neutralized by using one or more kinds of nonvolatile alkali compounds and one or more kinds of volatile alkali compounds. |
