摘要：

LiNi1/3Co1/3Mn1/3O2 powders have been successfully prepared via a newly developed microwave-hydrothermal method. Monophasic powders with an alpha-NaFeO2 structure were obtained. The particle sizes of the microwave-derived powders were in submicron order (0.2-0.3 Furl) and were much smaller than those of the powders synthesized via coprecipitation reaction (1-3 Em). The microwave-hydrothermal route not only shortened the required reaction time but also improved the electrochemical performance of the product. Electrochemical analysis indicated that the microwave-derived LiNi1/3Co1/3Mn1/3O2 powders exhibited a higher capacity than those derived from coprecipitation method. The capacity fading ratio of the microwave-derived powders was lower than that of the powders obtained via coprecipitation route, according to the results of high C-rate tests. (c) 2008 Elsevier B.V.
