摘要

磷酸铁锂(LiFePO₄)因其优异的性能,是极有发展潜力的锂离子动力电池用正极材料,但材料本身较低的电导率制约了其大规模应用。采用高导电碳材料对LiFePO₄进行表面包覆可有效解决这一问题。综述了LiFePO₄表面碳材料包覆改性研究进展,对碳材料包覆提升LiFePO₄正极材料电化学性能的作用机制进行了阐述,并对LiFePO₄正极材料的研究方向进行了展望。

Abstract

Olivine-structured lithium iron phosphate (LiFePO₄) is considered as one of the most promising anode materials for lithium-ion high power batteries due to its excellent performance.However,the low conductivity of the material itself restricts its large-scale commercial application.Coating conductive carbon materials on particles surface can effectively solve this problem.Some recent researches progress on surface modification of LiFePO₄ with different carbon-containing materials were summed,and explained the mechanisms of modification.Finally,an outlook for the research direction of LiFePO₄ anode materials was given.
