Lithium nickel -manganese oxide, as an athode material, is with good cycling performance, high capacity, a single high discharge platform. Therefore, many researchers focus on the research of this material of the lithium- battery in recent years. Different synthetic methods and synthetic conditions on the lithium nickel - manganese oxide have a great impact on its morphology and its performance. The solvent- gel, solid- state and molten salt methods were used to synthesis the production. X- ray diffraction (XRD) ,scanning electron microscopy (SEM) test were employed to examine the structure and to study the morphology of the resulted product, thus finding the impactions of synthetic methods to the productionsj morphology and its performance, then find out the best method and conditions for the synthesis of lithium nickel- manganese oxide (LiNi0.5Mn1.5O4 ) in the lithium- ion battery.
