Structure, Thermal and Conductivity Behavior of Vanadium Substituted Li_1.4Ti_1.6Al_0.4 (PO₄)_2.9(VO₄)_0.1 NASICON-Type

Abstract:

The material with NASICON-type structure, lithium aluminum titanium phosphate with vanadium substituting phosphorous (Li_1.4Ti_1.6Al_0.4(PO₄)_2.9(VO₄)_0.1) (LATPV) has been synthesized via solid state method. The X-ray powder diffraction analysis shows the effect of vanadium in the composition LATPV. Various secondary phases have been observed due to vanadium substitution which leads to low ionic conductivity of σ = 2.5 x 10^-5 (Ωm)^-1. The thermal analysis indicated that the reaction of chemical mixture become stable at round 460 °C which indicated an improvement in the material densification.
