| 摘 要： | 橄榄石结构的LiFePO4具有电压平台平稳、价格低廉、原料丰富和环境友好等优点，得到了人们的广泛关注. 然而，纯LiFePO4的离子和电子导电性较差，其大范围应用受限. 研究表明，对LiFePO4表面进行碳包覆可以有效提升其电化学性能. 结合国内外研究现状，本文综述了不同的碳包覆方法、碳源种类对LiFePO4电化学性能的影响，以及碳包覆提升LiFePO4正极材料电化学性能的作用机制.

| Abstract: | Olivine-structured LiFePO4 has been received much attention because of its flat voltage profile, low cost, abundant material supply and better environmental compatibility. However, the poor electronic and ionic conductivities have limited its application in industry. One of the best methods to improve the electrochemical performance is carbon coating. In this review, we summarize the recent developments of LiFePO4/C cathode. Moreover, the different effects caused by coating methods and carbon sources, as well as the mechanism of carbon coating on the properties of LiFePO4/C are reviewed. |
