摘　　要：作为电动车具有竞争力的正极材料磷酸铁锂吸引了很多的关注。了解磷酸铁锂电池的失效原因或机理,对于提高电池性能及其大规模生产和使用非常重要。综述了近年来磷酸铁锂动力电池失效的研究进展,讨论了杂质、化成方式、存储条件、循环使用、过充和过放等对电池失效的影响。Lithium iron phosphate（Li Fe PO4） battery,as a competitive cathode material for electric vehicle,attracted a lot of attention. However, issues concerning causes or mechanisms for failure needed to be solved in improving performance, large scale production and application. In this review, the research progress in failure of power Li Fe PO4 Batteries was focused, including the effects of impurity, formation, storage, cycle, over-charge and over-discharge,etc.
