摘要：

Nanostructured Li[Ni1/3Co1/3Mn1/3]O-2 cathode material is prepared by hydroxide coprecipitation at 273 K. The preparation conditions such as chelating agent amount and reaction time are varied to optimize the physical and electrochemical properties of LiNi1/3Co1/3Mn1/3O2. The structural, morphological and electrochemical characteristics of the prepared LiN1/3Co1/3Mn1/3O2 are characterized by XRD, SEM and galvanostatic charge-discharge cycling. The optimized material has nanostructured particles and well ordered layered structure, and it also exhibits a high discharge capacity and good high-rate capability. Synthesis at 273 K prevents the growth of the particles and produces nanostructured Li[Ni1/3Co1/3Mn1/3]O-2, which makes it more favorable to high power applications. (C) 2010 Elsevier B.V.
