Abstract
$LiNi_{0.5}Mn_{0.3}Co_{0.2}O_2$ active material was prepared by simple-combustion method and investigated as the cathode material for li-ion battery. The structural characterization was analyzed by X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM), respectively. The XRD patterns of $LiNi_{0.5}Mn_{0.3}Co_{0.2}O_2$ sample was indicated a phase of layered hexagonal structure. The size of particles has not uniform diameters ranging from 100 to 300 nm. The electrochemical performance of the $LiNi_{0.5}Mn_{0.3}Co_{0.2}O_2$ was measured by Cyclic Voltammetry and galvanostatics. The $LiNi_{0.5}Mn_{0.3}Co_{0.2}O_2$ shows the discharge capacity of ~162 mAh/g in the range of 2.8 to 4.3 V at the first cycle.
