Abstract
A non-aqueous electrolyte secondary battery that includes a positive electrode having a positive electrode active material layer and a positive electrode current collector; a negative electrode having a negative electrode active material layer and a negative electrode current collector; a separator interposed between the positive electrode and the negative electrode; and a non-aqueous electrolyte solution, which are enclosed in an exterior material. The positive electrode active material layer includes a lithium transition metal oxide having a layered crystal structure, and the negative electrode active material layer includes a lithium titanium oxide having a spinel-type crystal structure, and having a thickness of 20.0 μm or more and 33.4 μm or less. A ratio (R) between the thickness of the positive electrode active material layer and the thickness of the negative electrode active material layer is 0.59≤(R)≤1.50 or 0.59≤(R)≤1.14.
