本文从原理和结构上介绍了应用于电动汽车上的燃料电池、飞轮电池、超大容量电容器和核电池等几种新型动力电池。
The article describes the principle and construction of the new power-cell for electric vehicles, such as fuel cell, flywheel cell, super capacity capacitor and nuclear cell, etc.
电网级电池将大大提高能效，比如允许存贮太阳能用于在夜间，或者存储一个核电厂在夜间发出过多的电，以供白天使用。
Grid-scale batteries would boost efficiency by allowing solar energy to be used at night, for example, or excess power from a nuclear plant to be stored for later.
而核电厂的电池在地震后几个小时内保持供电，确保了更多照明及其他电力需求。这些都降低了抢救的难度。
The power plant's batteries were still working in the first hours after the quake as well, so more electricity would have been available for illumination and other power needs.
一旦辅助电池用尽，核电站将无法继续冷却反应堆内核以及乏燃料池。
When auxiliary batteries were exhausted, the plant was without power to continue cooling reactor cores and spent fuel pools.
