Abstract

A slurry for a positive electrode of a lithium-ion secondary battery. Also disclosed is a positive electrode for a lithium-ion secondary battery obtained using the slurry for a positive electrode of a lithium-ion secondary battery, and a production method for the electrode; and a lithium-ion secondary battery provided with the positive electrode for a lithium-ion secondary battery, and a production method for the battery. The slurry for a positive electrode of a lithium-ion secondary battery includes a positive electrode active material (A), a conductive auxiliary agent (B), a resin binder (C), a thickening dispersant (D), and water (E), wherein the thickening dispersant (D) includes a polyalkylene oxide having a phenyl group in a side chain thereof.
