Abstract: | Li+ NASICON based mixed conducting glass-ceramic composites have been developed by mechanical milling assisted synthesis where the mixed ion conducting glass [90V2O5-10P2O5] (abbreviated as VOPO) has been externally dispersed in LiTi2(PO4)3 (LTP). The glass-ceramic with a composition 10(VOPO-0h)-90(LTP-18h) (in wt%) has been structurally and electrically characterized. XRD shows no precipitation of any crystalline phase from VOPO in resultant glass-ceramic composite. The highest total conductivity has been found to be ∼10−5 Ω−1cm−1 at 100 °C which is relatively higher than that of LTP. The total electrical transport is found to be due to the conduction of electrons and Li+ ions in the composite. Reversible cyclic voltammetry scans suggest ohmic nature of the composites. These materials have been found to be suitable as cathodes for Li+ ion battery applications. |
