<p>An electrode structure possessing improved flexibility and adhesion between electrodes and collectors with reduced amount of binder, in an electrode for a battery comprising electrode active material and binder. The binder composition comprises a fluorine resin (A) dissolvable in a predetermined organic solvent and a resin (B) which is not dissolvable or partly dissolvable in said predetermined organic solvent, said fluorine resin (A) comprising at least one polymer selected from the group comprising a fluorine polymer (A1) whose solution dissolved in N-methylpyrolidone at a concentration of 8 % by weight possess a viscosity of 0.3 Pa.s to 20 Pa.s and a fluorine polymer (A2) having polar group, a weight ratio of A/B being 99/1 to 1/99.</p> |
