【 摘 要 】

Layered Mg doped LiNi0.5Mn0.5O2materials have been synthesized by sol-gel method. The physical properties of these materials were examined by XRD, FESEM and FT-IR studies. From XRD patterns, the phase formation of α-NaFeO2layered structure with space group is confirmed. The surface morphology of the synthesized materials has been examined by FESEM analysis in which the average particle size is found to be about 2 - 2.5 μm. These materials show some changes in the local ion environment, as examined by FT-IR studies.
