| 摘 要： | LiFePO4以其价格便宜，稳定性好，无毒等优点而倍受关注。但是非纳米LiFePO4的电子导电率低及扩散系数小限制了其在锂离子电池领域的大规模应用。而纳米电极材料以其特有的优点很好的解决了这些问题。本文主要综述了国内外合成纳米级LiFePO4 的不同方法及所得材料的对电化学性能和相关机理，以及纳米LiFePO4作为锂离子正极材料存在的问题。

| Abstract: | Lithium iron phosphate (LiFePO4 ) has been attracting enomous research interest for its lower cost, high stability, non-toxicity. The extensive use of LiFePO4 in Li-ion batteries is limited by poor electronic conductivity and low lithium ion diffusion limited the application of non-nanos-cale LiFePO4. Nano-scale electrode materials overcome these disadvantages. This paper overcomes chiefly the methods of synthesizing nano-scale LiFePO4, the electrochemical performance of nano-scale LiFePO4, the mechanism of nano-scale LiFePO4 some problems of nano-LiFePO4 as cathode in Li-ion batteries. |
