Abstract
The electronic structure of the spinel-type LiMn 2 O 4 as the cathode material for the application in secondary batteries was probed using both MnK- andL 23 -edge X-ray absorption near edge structure (XANES) spectra. Based on the energy shifts of the absorption peaks in the XANES spectrum correlated to the effective charge, the valence of Mn in LiMn 2 O 4 was determined to be ~4+. This suggests that the chemical substitution of low valent Li + ions into the Mn sites is possible to result in high valence of Mn. © 1997 Academic Press.
