Paper battery could take over for lithium-ion in EVs and beyond

It is a carbon-carbon battery right? Calling it just paper... when normally a battery name refers to the electrode or electrolyte chemistry is kind of confusing.

I remember making the carbon inks was expensive but they must have figured it out for it to beat lithium now. Everything shown still looks like sample sheet batteries, no other form factor, roll, tube, stack, etc. Curious if the power density is sufficient that you can stuff those into existing lithium cell sizes or if you will need sonething larger.
