  "textContent": "A non-aqueous electrolyte secondary battery that is an exemplary embodiment of the present invention, wherein a positive electrode contains a lithium-transition metal composite oxide containing Ni, Al and Sr as a positive electrode active substance. In the lithium-transition metal composite oxide, the content of Ni is 80-95 mol %, the content of Al is 8.0 mol % or less, the content of Sr is 1.2 mol % or less, and the proportion of metallic elements other than Li that are present in a Li layer is 0.5-2.0 mol %. A negative electrode has a Sr-containing coating film formed on a surface of a negative electrode mixture layer. The content of Sr in the coating film is 20-400 ppm relative to the total mass of the negative electrode mixture layer and the coating film.",
