摘　　要：内阻是衡量锂电池功率性能和评估锂电池寿命的重要参数,一直以来也备注关注。锂电池初始的内阻大小主要由电池的结构设计、原材料性能和制程工艺决定。在实际使用过程中,电池内阻的变化还受到温度、SOC等多种因素影响。本文从以上各方面对近年来关于内阻特性的研究成果进行了概述。Internal resistance is an important parameter to measure the power performance and to evaluate the life of lithium-ion batteries, it has been taken more and more attentions in recent years. The initial internal resistance of lithium batteries is mainly determined by the structure design, raw material performance and manufacturing process. The evolution of internal resistance of the battery is also affected by temperature, SOC and other factors when they are used in the daily life. In this paper, the research results on internal resistance characteristics are summarized which are mentioned above.
