双极叠层MH/Ni电池的研究

Research of Ni/MH battery with bipolar stack design

双极叠层MH/Ni电池是很好的混合电动车(HEV)用高比功率电池,能够提供较高的电压和功率密度,与传统的圆柱形和方形MH/Ni电池相比,它具有性能上和成本上的双重优势。实验采用特殊的密封技术,制成包含5只单体电池的叠层电池,并测试其电化学性能,认为封口活化的贫液设计电池性能较好,进一步优化了电池设计。

Ni/MH batteries with bipolar design offered some advantages as a power storage system such as hybrid electric vehicles. It offered performance advantages and cost reductions as compared with conventional cylindrical and prismatic designs. Dealed with some aspects of combining five cells in a special way of edge seal,the performance of bipolar battery with a limited amount of starved electrolyte was obviously better than the battery with an abundant electrolyte.
