摘要：
An object of the present invention is to provide a high-capacity, low cycle deterioration lithium secondary battery in which the positive electrode is provided with a titanium composite oxide such as Li2NiTiO4. A lithium secondary battery 100 provided by the present invention includes a positive electrode 10 and a negative electrode 20. The positive electrode 10 has a solid solution between Li2M1TiO4 (where M1 is at least one metal element selected from the group consisting of Mn, Fe, Co, and Ni) and LiM2O2 (where M2 is at least one metal element selected from the group consisting of Mn, Co, and Ni).
