Abstract

Disclosed is a battery electrode binder containing a polymer including (1) a constituent unit derived from a (meth)acrylate monomer (A) having a hydroxyl group, (2) a constituent unit derived from a vinyl ester monomer (B), and (3) a constituent unit derived from a polyfunctional (meth)acrylate monomer (C). Using the binder, an electrode is produced and adopted in a battery such as a lithium ion secondary battery. Obtained are: an aqueous binder that has a low environmental impact, has high adhesiveness, and in particular does not cause oxidative degradation in the electrode environment; and a battery and electrode using the binder.
