Co-sintering process of LiCoO2 cathodes and NASICON-type LATP solid electrolytes studied by X-ray diffraction and X-ray absorption near edge structure

The composites of a high-capacity cathode material in lithium-ion batteries, LiCoO 2 and an oxide-based solid electrolyte, Li 1.3 Al 0.3 Ti 1.7 (PO 4 ) 3 were sintered at various temperature and their reaction products were identified by XRD and XANES.
