摘　　要：研究了特殊集流结构的圆柱F型锌镍动力电池,按照混合动力汽车对电池性能的要求,从单体、模块、电池组不同层面对锌镍电池在混合动力汽车上的应用进行了系统的评估。设计的F型锌镍电池容量为10~13 Ah,比能量达到120 Wh/kg,正极端面集流结构使电池具有良好的倍率充放电性能,30 min可以充电至80%额定容量,10 C放电容量达到额定容量的94%,-29℃仍展现出良好的启动能力。特殊设计的锌负极外层导电膜阻止锌与钢壳直接接触,抑制副反应,提高了电池的循环稳定性,1 C循环寿命超过1200次,容量保持率在70%以上;启停循环达到20万次。过充电、过放电、外部短路、针刺情况下,电池均不起火、不爆炸。本研究为锌镍电池在混合动力汽车上的大规模应用提供了重要参考。The cylindrical F zinc-nickel battery(ZNB)with special current collecting structure was designed and developed.The application of ZNB in hybrid electric vehicle was systematically evaluated from different levels including cell,module and battery pack according to the requirements of hybrid electric vehicle battery.The capacity of the F cell is 10-13 Ah,and the energy density reaches 120 Wh/kg.The end face current collecting structure of cathode enables the battery to possess excellent rate charge/discharge performance,80%capacity can be charged in 30 minutes,94%rate capacity can be delivered at 10 C discharge rare,meanwhile it also shows excellent startability at-29℃.The specially designed outer conductive film prevents the zinc electrode from contacting the steel shell directly,inhibits the side reaction,and improves battery cycling stability.1200 cycles are achieved at 1 C with 70%capacity retention,and more than 200000 times start-stop life are obtained for start cycle.No fire or explosion happens after over charge,over discharge,short circuit and needling test.This investigation provides important reference for the largescale application of ZNB in hybrid electric vehicles.
