    • Abstract

       

      Vanadium substituted LiTi2(PO4)3 (LTP) samples of composition of Li1–𝑥[Ti2–𝑥V𝑥](PO4)3 (𝑥 = 0.0, 0.05, 0.10 and 0.15) have been prepared by solid-state reaction method. XRD data for these compositions indicated the formation of phase pure materials of rhombohedral structure with space group 𝑅$\bar{3}$𝑐 (167). Microstructural studies by scanning electron microscope indicated particle size in the range of 0.5–1 𝜇m. Electrochemical impedance studies showed that ionic conductivity is high for 𝑥 = 0.10 composition. a.c. and d.c. conductivity results up to 573 K are in accordance with the Jonscher’s power law. Cyclic voltammetry study showed its electrochemical stability in the voltage range from 0.5 to 3.5 V.
