<p>A binder composition comprising (1) an organic liquid substance, (2) polymer particles (A) insoluble in the substance, and (3) a polymer (B) comprising structural units derived from an ethylenically unsaturated carboxylic ester of general formula (I) and being soluble in the substance, wherein R1 is H, -CH¿3?, or COOH; R?2¿ is H, -CH¿3?, or CH2COOH; and R?3¿ is optionally substituted alkyl. This composition enables the production of electrodes having high smoothness, and use of such electrodes brings about lithium ion secondary batteries excellent in charging and discharging characteristics.</p> |
