In this work, valuable explorations have been carried out on the size and shape control of LiFePO4 nano-materials in ethylene glycol solution, and their electrochemical performances were carefully characterized. By changing the concentration of the reagents, the sizes of obtained LiFePO4 nano-materials were altered. When the concentration of FeSO4 reagent reached 0.15M, the obtained LiFePO4 nano-materials showed the minimum size and highest specific capability. By adding different amount of glucose, the morphology of the obtained LiFePO4 nano-materials were changed, but the electrochemical performance of these materials were not obviously influenced. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
