摘要
概述了双极性动力电池的原理、特点以及发展状况。指出电池内部的自放电是双极性锂离子电池有待解决的关键问题,并从双极性电极制备、电池密封以及结构设计3个方面做了详细描述和分析。双极性动力电池的研究对电动汽车及混合动力车用动力电池的发展具有重要意义。
The basic principles and characteristics of bipolar battery were introduced, and the research status ofbipolar battery was also reviewed. Furthermore, this paper points out the key problem of self-discharge of the batterycell due to electronic and ionic short circuit, and presented a description and analysis about the ways to solve thekey problem from the aspects of bipolar electrode preparation, battery sealing and structural design. The investigationof bipolar power battery is of great importance for the development of power system in electrical vehicles （ EV） andhybrid electrical vehicles （ HEV）.
