Abstract

 LiNi0.5Co0.5VO4 has been successfully synthesized by tartate precursor combustion method using Li2CO3, Co (NO3) 2.6H2O, Ni (NO3) 2.6H2O and NH4VO3 as a starting materials in deionized water with the subsequent calcination at 450-600oC for 12 h. The combustion and decomposition of tartate precursor were studied by TGA and compared with tartaric acid. It found weight loss at 50-450oC. The product showed a inverse spinel LiNi0.5Co0.5VO4 which confirmed by PXRD. The crystal and particle sizes improved when calcination temperature was increased. Raman and FITR were studied the vibration of product. They detected V-O stretching in VO4 tetrahedron, Li-O bending in LiO6 octahedron and Li-O-M (M=Ni and Co) stretching. The TEM showed morphologies that composed nano-particle of LiNi0.5Co0.5VO4.
