For a given voltage a capacitor will store a certain amount of charge.

电容会在一个给出的电压值下储存一定的电荷。

The idea is to harvest the energy and store it using a combination of a super capacitor and a lithium battery.

这个概念是利用一个超级电容器和一个锂电池组成的复合装置来收集和储存能量。

However, in contrast to batteries, a capacitor cannot store enough energy to power anything that lasts longer than a flash — some fraction of a second.

但是，相比电池，电容器储存的能量不足以维持任何比闪光时间长的时间，而闪光时间还不足一秒。

The computer industry constantly strives to pack more, and therefore smaller, components on to each chip, but the smaller a capacitor gets, the harder it is to store enough charge on it.

ECONOMIST: Combinatorial chemistry

Chemical electrodes of this sort can store a lot more energy than the static electricity of a capacitor.
