Structural investigation of Li1+xCrx(Ge0.2Ti0.8)2-x(PO4)3 glass-ceramics. Correlation with lithium transport
Li-based solid electrolytes have been extensively studied in the last decades for their application in batteries. Phosphates with NASICON-like structure have attracted much attention due to their high ionic conductivity and structural versatility. Currently, we have synthesized a new glass-ceramic in the system Li1+xCrx(GeyTi1-y)2-x(PO4)3 (LCGTP) which presents appreciable glass stability, homogenous nucleation and crystallizes a NASICON-type phase. We have then performed an investigation of the double substitution of Ti by Cr and Ge based on the LCGTP system, pursuing a compromise between the stability of the precursor glass and the electrical properties of the resulting glass-ceramic. A structural investigation by X-ray diffraction helped in finding a correlation between the unit cell volume of the crystalline phase and the ionic conductivity. Unfortunately, similar X-ray scattering factors for Ti and Cr prevented to go further in the information. We now propose to extend the investigation to neutron diffraction, which allows the distinction between Cr and Ti. We expect better insight on the origin of enhancement of conductivity in trivalent-doped NASICON-type compounds.
