Studies on structural and electrical properties on Lini0.5mg0.5vo4 For Li-Ion Batteries / Aida Fazliza Mat Fadzil … [et al.]

In this work, cathode material of LiNi0.5Mg0.5VO4 was synthesized in a pure state by organic synthetic procedure known as sol-gel method. The annealing temperature was defined at 5500C for 5 hours for this sample. The structural properties of the compound were characterized by X-ray diffraction. It shows that this- cathode material, produced crystallinity sample: The electrochemical characterization was carried out by Solartron Impedance Spectroscopy where the conductivities of the compound were measured at various temperature (250C, 350C, 450C, 550C and 650C). The relationship of the temperature is inversely proportional to the electrical conductivity of solid LiNi0.5Mg0.5VO4.-The highest conductivity is 1.40 x 10-4 S cm-1. Cyclic voltammetry were carried out and it shows the intercalation-deintercalation process for this material. -, Therefore, LiNi.0.5Mg0.5VO4 is a potential cathode material for lithium-ion batteries.
