纳米多孔金属材料由于其较高的表面积所以拥有良好的电子传输特性，这正好改善了其在导电双电容或电池上的电极性能。
They posses a high surface area for better electron transfer, which can lead to the improved performance of an electrode in an electric double capacitor or battery.
无极性（或二极性）电解电容器，可使用在极性转换的回路或直流回路上。
Non-polar (or Bi-polar) capacitors can be used in polaritiy- changing circuits or DC circuits.
如果电荷不能通过这种界面，它即是极性的，其电学行为等效一个电容。
If charge cannot cross the interface, it is said to be polarized and is electrically equivalent to a capacitor.
