PROBLEM TO BE SOLVED: To provide: a composition for a secondary battery electrode, simultaneously achieving storage stability of a slurry, binding properties, and electrode flexibility, and further improving battery cycle characteristics; and a secondary battery.SOLUTION: A composition for a secondary battery electrode includes an active material, a dispersion medium comprising water as a main component and a resin, and the resin has at least one of the functional groups represented by formulae (A1) to (A3) on the side chain. [In the formulae, Rrepresents an alkyl group, an alkenyl group, an alkynyl group or an aryl group, R-Reach independently represent a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, or an atom or an atom group which may form a salt with O.] |
