Abstract
A lithium mixed metal oxide containing Li, Mn and M (M represents at least one metal element, and is free from Li or Mn), and having a peak around 1.5 Å (peak A), a peak around 2.5 Å (peak B), and the value of I/Iis not less than 0.15 and not more than 0.9 in a radial distribution function obtained by subjecting an extended X-ray absorption fine structure (EXAFS) spectrum at K absorption edge of Mn in the oxide to the Fourier transformation, wherein Iis the intensity of peak A and Iis the intensity of peak B.
