The reason ultracapacitors may be able to bridge the gap between speed and endurance is that, like batteries, they use ions and an electrolyte rather than simply relying on the static charges.

超级电容器似乎能够兼备速度和耐久性这两个优势，这是因为和电池类似，在构造上它采的是用离子和电解液而不是简单依靠静电荷。

When voltage is applied in a first direction an ion bridge forms across through the electrolyte across electrodes making the resistor conductive.

当电压沿第一方向施加时，跨电极穿过电解质形成离子桥，使电阻器导电。
