Abstract

The purpose of the present invention is to provide: an aqueous binder having high adhesiveness, that in particular does not exhibit oxidative degradation in an electrode environment, and having little environmental load; and an electrode and a battery that use same. Disclosed is a battery electrode binder containing: (A) a constituent unit derived from a monomer having a hydroxyl group; and (B) a constituent unit derived from a polyfunctional (meth)acrylate having no more than 5 functions. An electrode is prepared using this binder and is used in a battery such as a lithium-ion secondary battery.
