Abstract
Provided is a binder composition for a non-aqueous secondary battery positive electrode, a composition for a non-aqueous secondary battery positive electrode, a positive electrode for a non-aqueous secondary battery, and a non-aqueous secondary battery that can favorably maintain the balance among the paste stability of the composition for a positive electrode prepared using the binder composition, the peel strength of the positive electrode mixed material layer formed using the composition for a positive electrode, and the output characteristics of the secondary battery using the positive electrode including the positive electrode mixed material layer. The binder composition comprises: a polymer; and an organic solvent, wherein the polymer contains at least one of a conjugated diene monomer unit and an alkylene structural unit, and contains a nitrile group-containing monomer unit, and solution turbidity of the binder composition for a non-aqueous secondary battery positive electrode is 1 or more and 80 or less.
