Dynamic study of sub-micro sized LiFePO4 cathodes by in-situ tender X-ray absorption near edge structure

Dynamic studies of LiFePO4 cathode at low rate have been conducted through in-situ X-ray absorption near edge structure at both Fe and P K-edge. A fluctuation of the FePO4 (or LiFePO4) content associated with intermediate phases during charge and discharge was revealed spectroscopically.253
