Original Abstract Submitted

The positive electrode contains a lithium-transition metal composite oxide. With respect to the lithium-transition metal composite oxide, the content of Ni is from 80% by mole to 95% by mole relative to the total number of moles of metal elements excluding Li, and the content of Mo is less than 3% by mole relative to the total number of moles of metal elements excluding Li. The negative electrode comprises a negative electrode mixture layer that contains a negative electrode active material, and a coating film that is formed on the surface of the negative electrode mixture layer, while containing Mo. The content of Mo in the negative electrode is from 0.5 ppm to 120 ppm relative to the total mass of the lithium-transition metal composite oxide in the positive electrode.
