【 摘 要 】

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.
