Tunneling effect in Supercapacitors ??? Hi everyone! This is my first post … so please bear with me! My question concerns the double layer developing within every supercpacitor / EDLC http://en.wikipedia.org/wiki/Electric_double-layer_capacitor" [Broken] Considering the interface electrode – electrolyte and the ions which are only a few angström apart from the electrode I can’t help but wonder why the tunneling effect (electron on the electrode side tunneling to the positive ion on the electrolyte side) can be completely neglected. Could it be that the tunneling effect is indeed responsible for the long-term self discharge characteristics every EDLC exhibits?
