Abstract

Provided are a method for manufacturing a non-aqueous electrolytic solution secondary battery in which a positive electrode collector, a positive electrode active material layer, a separator, a negative electrode active material layer, and a negative electrode collector are laminated in this order, the method including applying a slurry for forming a positive electrode onto the positive electrode collector to form a slurry-like positive electrode active material layer, and adding a solvent having a vapor pressure of 4.0 kPa or more to the slurry-like positive electrode active material layer, the slurry for forming a positive electrode, containing a positive electrode active material at a content of 75% by mass or more, a conductive auxiliary agent, an electrolyte, and a non-aqueous solvent (I) in which a content of the solvent having a vapor pressure of 4.0 kPa or more is less than 1.0% by mass; and a non-aqueous electrolytic solution secondary battery which can be obtained by the manufacturing method.
