摘　　要：在文献、专利调研基础上,统计和分析了电动汽车用锂离子电池的温度敏感性。结果表明:低温和高温都影响电动车用锂离子电池的性能和寿命,从而影响其应用与市场普及。缓解该问题的技术途径可以是:电池原材料改性、优化电池设计、电池系统热管理。当前的研究热点是:正负极材料的微观改性,以提高其电子导电率和离子导电率;优化设计电极结构和电池结构,以均匀电池内部的热分布和电分布;研发低温下电池交流预热与充电的新方法;联合应用液冷方案。Temperature sensitivity statistics were collected and analyzed for lithium-ion battery （LIB） of electric vehicles （EV） based on survey of papers and patents. The results show that low and high temperatures have great effect on the performances, respectively, severely affecting the operation and the market penetration of EVs. To mitigate this problem, some techniques are used including changing raw material properties, optimizing cell designs, and using battery thermal management systems （BTMS）. Further research for temperature sensitivity is to improve the cathode materials and anode materials of LIB to increase electric conductivities and ionic conductivities; to optimize electrode structures and cell structures to uniform thermal and electrical distribution; to develop new protocols for alternating current （AC） preheating/charging at low temperatures; and to incorporate the liquid cooling method.
