研究团队增加了体组件，比如双倍的电容器（这是一种能在换极前一直充电的元件）。

Instead, the team added body components that double as capacitors, devices that hold an electrical charge until they are tapped.

而且，和大部分可充电式电池相比，超级电容器有更长的工作寿命，长期来看更显优势。

And compared with most rechargeable batteries, supercapacitors tend to have a longer working life. In time that too would become a more obvious benefit.

EEStor公司推测采用了这样的储能装备后，将能造出快速充电的电动汽车——这当然还是要在电容器的帮忙下。

One use of such a bank, the firm suggests, could be the rapid charging of electric cars—which would, of course, also be fitted with capacitors.
