ABSTRACT

 

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 500C for 10 hours and calcined at different temperatures in the range between 650C and 950C 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.
