Can't reply to your other comment yet, so I'll do it here. I think that this is a "duck typing" memristor: You can use it as a memristor, but it's not what was predicted. Anyway, if you're interested, watch the video I linked (thanks to @achille): It really explains what this is all about. If you have some basic understanding of semiconductors physics I think you'll enjoy it :)

I think I get what you're going for now, sorry it took a while for the coin to drop. Just like a battery can look like a capacitor under some conditions it really isn't a capacitor. Capacitors and batteries can be described using the same basic laws, even though the fundamental mode of operation is completely different. They have the same basic properties: - internal resistance - a certain capacity - a breakdown voltage - you can charge them - you can discharge them by connecting the terminals (hopefully through some suitable load) - both exhibit self-discharge - have a certain amount of inductance And yet the one is a real capacitor whereas the other one is an electro-chemical device, only when you open one up or when you charge/discharge it a large number of times can you see that there is a real difference between the two, superficially they are interchangeable for some applications. Does that get it right?

  That's a good comparison, as far as I understand this thing. With the exception that the "real memristor" is only a theoretical device.

  An electrolytic capacitor is an electro-chemical device itself. Also, like a battery, if the "electrolyte" is not without solvent then it is a liquid-state device. As opposed to a film & foil capacitor which is a solid-state device. Batteries generate a characteristic cell voltage as a result of a chemical reaction. Capacitors store any voltage up to their maximum rating, electrolytics have higher capacity/size ratio than film & foil due to the chemical help of the electrolyte, but do not generate voltage on their own, only store what is supplied from a power source.
