The point here isn't the electolyte. It's the electrodes, which is what actually stores and releases the charge(s).
Yeah, and that is exactly the point these idiots miss in their very first sentence, which I quoted and which you somehow forget to remember in your reply.
To...ahem..recap: The idiots equate in the first sentence electrochemical capacitors with the new 'super capacitors', wholly oblivious to the fact that most all caps are in fact electrochemical caps. Just how hard is that to understand???!!! You see, these idiots don't have even a basic grasp of simple first principles. q.e.d.
