I'm reading about electrochemical capacitors here:
httpCOLON//electrochemDOTcwruDOTedu/ed/encycl/art-c03-elchem-cap.htm (Website won't let me post a URL until I've made 15 posts...)
Do electro chemical capacitors actually store charge indefinitely ? Or do they deplete as soon as the charging electric field is removed ?
I wonder this because the operating dielectric seems to be an ionic medium and wouldn't the ions promote conductivity between the positive and negative plates and thus wouldn't the capacitor self discharge ?
Can an ionic material be a dielectric and if so, why doesn't the capacitor self discharge ?
Thanks
