摘要：

Nano- and submicrometer LiMn2O4 spinel particles were successfully synthesized by a modified citrate route with spontaneous combustion at 250 degreesC followed by a calcination process. Citric acid was used as the chelating and combustion-assistant agent. The synthesized LiMn2O4 showed a high electrochemical performance compared with commercial LiMn2O4 materials. The initial discharge specific capacity reached 130 mAh/g. The effects of the processing factors and element substitution on the microstructure and electrochemical performance of LiMn2O4 were also examined. (C) 2002 Elsevier Science B.V.
