Effects of chromium substitution on the chemical bonding nature and electrochemical performance of layered lithium manganese oxide
Article Abstract:
The effects of chromium substitution on the chemical bonding nature of LiMn1-xCrO2 are investigated by performing X-ray absorption spectroscopic analyses. The result suggests that the superior electrochemical performance of LiMn1-xCrxO2 could be attributed to the enhanced stability of the layered manganese oxide lattice because of the presence of a chromium ion in the octahedral site of the transition metal oxide layer.

Origin of the metallization of c-axis resistivity upon iodine intercalation into Bi2Sr2CaCu2O(sub 8+delta)
Article Abstract:
A study was conducted on the origin of metallization of c-axis resistivity upon intercalation of Iodine into Bi2Sr2CaCu2O(sub 8+gamma) by performing I LI-edge angle-resolved X-ray absorption spectroscopic (XAS) analysis. The analysis suggests that there is a significant anisotropy in the 1 5p hole distribution of the intercalated iodine layer.

Variation of the chemical bonding nature of LiMn2-Ni(sub x)O4 spinel oxides upon delithiation and lithiation reactions
Article Abstract:
The effect of nickel substitution on the chemical bonding nature of spinel lithium maganate is examined. Comparative X-ray absorption spectroscopic analyses for Ni- and Cr-substituted LiMn(sub 2-x)M(sub x)O4 (M= Ni and Cr) compounds are discussed.
