Non-aqueous electrolyte secondary battery

Abstract

The non-aqueous electrolyte secondary battery (10) includes an electrode body (14) and a non-aqueous electrolyte. The electrode body (14) includes a positive electrode (20), a negative electrode (30), and a separator (40). The electrode body (14) is formed by winding the positive electrode (20) and the negative electrode (30) with the separator (40) in between. The electrode body (14) has an adhesive layer (50), which is disposed between the positive electrode (20) and the separator (40) and between the negative electrode (30) and the separator (40). The non-aqueous electrolyte contains an alicyclic diisocyanate in an amount of 0.1% by mass or more and 1.0% by mass or less of the total mass of the electrolyte.
