What would a hybrid super capacitor graph look like then?

Could there be more than one type of curve that they could produce?
Every curve you'll find has regions that are capacitor-like. At higher currents, they become more and more capacitor-like. Feel free to provide us with counter-examples.

Let's attempt to be reasonable here - we are being shown devices that physically look exactly like readily available and cheap LTO cells. They are the same size and shape. They perform electrically exactly like LTO cells. They do not perform electrically like capacitors, at all, so how can they be capacitors?

There has been no announcement in scientific or engineering publications that would support the position that ultra/supercapacitors of any chemistry of this size exist today with this capacity, in any lab anywhere, much less in commercial quantities, at any price. Who is supposedly manufacturing these miracle devices?

Given all of that, why would anyone conclude anything other than that these are the readily available, cheap LTO cells?
There is zero evidence that they are anything else, and strong evidence that they are exactly what they appear to be.

Putting all of that aside for a moment, we have the more recent claim that readily available carbon-LTO 1.5V cells are another graphene supercapacitor product.
Yet they are clearly the batteries pictured earlier in the thread with a sticker attached, and are not supercapacitors.

How do you explain that? Someone is being misleading here, and it would appear to be whoever is attaching those stickers to cover the printed information that identifies the devices as batteries. I await your explanation with interest, @whysomean.
