The nanoparticle Li[Li0.2Mn0.54Ni0.13Co0.13]O2 powder was synthesized via co-precipitation method in non-aqueous system. The structure, morphology and electrochemical behaviors of the synthesized material were characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and galvanostatic charge-discharge tests. XRD pattern revealed that the nanosize Li[Li0.2Mn0.54Ni0.13Co0.13]O2 powders had layered hexagonal structure with low cation mixing. SEM image exhibited the nanoparticles were synthesized via non-aqueous coprecipitaiton method. And galvanostatic charge-discharge tests comfirmed the Li[Li0.2Mn0.54Ni0.13Co0.13]O2 electrode had good electrochemical properties, especially the high rate discharge capability such as 10C, which make it meet the requirement for high power application such as EV or HEV.
Key words: Li[Li0.2Mn0.54Ni0.13Co0.13]O2 / nanoparticle / high rate
