Abstract
The present invention provides a non-aqueous electrolyte secondary battery that comprises a positive electrode sheet comprising a positive electrode active material layer, and a negative electrode sheet comprising a negative electrode active material layer. The positive electrode sheet and the negative electrode sheet are arranged such that the positive electrode active material layer and the negative electrode active material layer face each other. The negative electrode active material layer comprises a face-to-face region Nthat faces the positive electrode active material layer and a non-face-to-face region Nthat does not face the positive electrode active material layer. The non-face-to-face region Nincludes a high density part Nhaving a density higher than that of the region face-to-face N.
