In-situ neutron diffraction studies of LiCoO2 cathode material for Li-ion batteries

Abstract: LiCoO2 as cathode for Li-ion batteries suffers from a large capacity fading after extended cycling. The ordered structure (Li+ and Co3+ atoms occupy alternate (111) layers of the rock salt structure) undergoes several phase transitions during charge which cause structural degradation of the material. In fact, the structural stability of Li1-xCoO2 is maintained only for a limited compositional range 00.5. This is attributed to the structural transition from a hexagonal to monoclinic phase. In order to monitor the phase transitions in LiCoO2 as a function of charge/discharge, we plan to use the new in-situ cell especially designed for Polaris.We expect to conduct Rietveld refinement for the LixCoO2 phases as a function of x and extract relevant structural information by Rietveld refinement.
