Abstract: Provided is a slurry composition for a positive electrode that has excellent dispersibility and enables production of a secondary battery that can display good output characteristics. The slurry composition for a non-aqueous secondary battery positive electrode contains a positive electrode active material, a conductive material, a particulate polymer, and a polyhydric alcohol polycondensate. The positive electrode active material includes an iron-containing compound. The particulate polymer includes a hydroxyl group-containing monomer unit.

Abstract: Provided is a composition for a non-aqueous secondary battery functional layer with which it is possible to form a functional layer that can cause a battery member including the functional layer to have a good balance of blocking resistance and adhesiveness to another battery member after immersion in electrolyte solution. The composition for a non-aqueous secondary battery functional layer contains a particulate polymer and non-conductive porous particles containing an organic material. The particulate polymer has a core-shell structure including a core portion and a shell portion at least partially covering an outer surface of the core portion.
