摘要： A positive electrode active material with high charge and discharge capacity is provided. A positive electrode active material with high charge and discharge voltage is provided. A secondary battery which hardly deteriorates is provided. A highly safe power storage device is provided. A novel secondary battery is provided. The positive electrode active material contains cobalt, oxygen, and fluorine and includes a bond of the cobalt and the fluorine in a surface portion or the vicinity of a grain boundary. By having the bond with fluorine, at least part of cobalt is high-spin (paramagnetic) Co2+. Thus, in ESR analysis, the spin concentration at 113 K is higher than the spin concentration at 300 K by 1.1×10−5 spins/g or more.

摘要： A positive electrode active material in which the number of defects that cause deterioration is small or progress of the defect is suppressed is provided. The positive electrode active material is used for a secondary battery. The positive electrode active material contains lithium cobalt oxide containing an additive element. After a cycle test is performed on a cell that uses the positive electrode active material for a positive electrode and a lithium electrode as a counter electrode, the positive electrode active material includes a defect and contains at least the same element as the additive element in a region in the vicinity of the defect. The additive element is contained also in a surface portion of the positive electrode active material.
