Beschreibung
Zusammenfassung:	The invention provides a slurry for a positive electrode of a lithium-ion secondary battery, wherein the slurry increases the dispersibility of a positive electrode active material, improves the coatability on a current collector of slurry for a positive electrode, and makes it possible to obtain a lithium-ion secondary battery having a low initial resistance value. The invention also provides 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) comprises a polyalkylene oxide having a phenyl group in a side chain thereof.
