Abstract: | LiNiVO4 was prepared from Li2CO3, Ni(CH3COO)2·4H2O and NH4VO3 using tartaric acid as a complexing agent with 1:1–1:4 mole ratios of metals:tartaric acid and subsequent calcination at 350–700 °C for 6–12 h. Inverse spinel LiNiVO4 was detected using XRD. FTIR and Raman analyses revealed the presence of stretching band of VO4 tetrahedrons. Only Ni, V and O were detected by EDX. The 1:4 mole ratio for the product with 450 °C calcination for 6 h analyzed by SEM, TEM and electron diffraction (ED) composes of LiNiVO4 nano-powder with 10–30 nm in diameter. |
