摘要： There is provided a battery including a positive electrode, a negative electrode, and an electrolyte. The positive electrode includes a positive electrode active material layer, on at least one surface of a positive electrode current collector, including a binder and a positive electrode active material of a deoxidized lithium transition metal composite oxide. The positive electrode active material layer shows first and second peaks of oxygen amounts generated from a type of the positive electrode active material in the positive electrode active material layer when the positive electrode active material layer is heated in a charge state of higher than or equal to 4.2 V and lower than or equal to 4.5 V in a lithium antipode potential, the second peak appearing in a temperature region higher than a temperature region of the first peak. At least the second peak appears in a temperature region higher than 220° C.
