Valence evaluation of LiMnO2 and related battery materials by x-ray absorption spectroscopy
Valence evaluation of LiMnO2 and related battery materials by x-ray absorption spectroscopy
We present an x-ray absorption study of the oxidation states of transition-metal-ions of LiMnO2 and its related materials, widely used as cathodes in Li-ion batteries. The comparison between the obtained spectrum and the configuration-interaction cluster-model calculations showed that the Mn3+ in LiMnO2 is a mixture of the high-spin and low-spin …
