In this work, LiNi0.5Mn1.5O4, which is a potential cathode active material in the 5 Vclass, is prepared by the solid-state redox method. The precursor material was obtained when the mixture reactants were heated at 500°C for 10 hours and calcined at different temperatures in the range between 650°C and 950°C for 12 hours. The structures of the synthesized materials were verified with X- ray diffraction (XRD) measurements and Scanning Electron Microscope (SEM). The electrochemical properties i.e. the chargedischarge technique were determined using Solartron 1470.
