Abstract:
According to the present invention, there is provided a positive electrode active material for a lithium secondary battery, including a lithium manganese complex oxide having a spinel structure. In the lithium manganese complex oxide, the ratio (A/B) of a peak intensity A at 654 eV of the Mn-L absorption edge and a peak intensity B at 537.5 eV of the O-K absorption edge, which are measured by X-ray absorption fine structure (XAFS) analysis based on a total electron yield method, satisfies 0<(A/B)≤0.2.
