Abstract: A producing method for a lithium-ion secondary battery includes a positive-electrode-plate producing step of producing a positive electrode plate having a positive active material layer on a surface of a positive current collecting foil, an electrode-body producing step of producing an electrode body provided with the positive electrode plate and a negative electrode plate, a housing step of housing the electrode body inside a battery case, an injecting step of injecting non-aqueous electrolytic solution into the battery case housed with the electrode body to produce an injection-completed battery, and an initial charging step of initially charging the injection-completed battery. The injecting step is to inject the non-aqueous electrolytic solution into the battery case housed with the electrode body in which a water content of the positive active material layer is 100 ppm or more.

Abstract: Provided is a method for producing a non-aqueous electrolyte secondary battery. A negative electrode core of a negative electrode plate has front and back surfaces each with a surface roughness different from the other Rz. In a wound electrode body, a wound negative electrode core-exposed portion is formed at one end portion in the winding axis direction. In the wound negative electrode core-exposed portion, the surface roughness of the negative electrode core-exposed portion on the outer surface side is lower than the surface roughness on the inner surface side. A negative electrode current collector is placed on the outer surface of the wound negative electrode core-exposed portion and the negative electrode current collector is resistance-welded to the wound negative electrode core-exposed portion.
