Abstract
A lithium ion secondary battery electrode according to the present invention includes (A) a non-fluorinated polymer; (B) an active material; (C) a thickener; and (D) a conductive auxiliary agent. An elution ratio of (A) the non-fluorinated polymer in an electrolytic solution solvent at 60° C. is equal to or less than 1.0 mass %, and a swelling ratio of (A) the non-fluorinated polymer in the electrolytic solution solvent at 60° C. is equal to or more than 10 mass % and equal to or less than 50 mass %.
