Abstract

Cr-doped LiMn₂O₄ spinels were synthesized by a solid-state reaction. X-ray photoelectron spectroscopy (XPS) investigation shows the structural and valence changes of the Cr-doped Li_xMn_2-yCr_zO₄ spinels with increasing Cr content. A conversion of Cr³⁺ to Cr⁶⁺ is found in the heavy-doped samples at 0.20<z<0.99. The further increase of z value results in the appearance of a second phase. The effects of Cr-doping on the structures and oxidation states are discussed.
