Not particularly suitable for an eV but is a taste of things to come.

40C max
10,000 cycles 100% DOD
100,000 cycles 10% DOD
So the short answer is NO but the long answer is YES.

Assuming a typical 250wh/km energy consumption, one of those cells could move an EV approximately 4cm Image

And it seems like it only works out to 10wh/kg energy density? But still interesting tech, for sure.

Still, not bad for the *volume* of about 3 postage stamps!

[ Edit: OK, make that about 6 stamps; you'd need two layers by very rough calculations. ]

I'm too lazy to check, but it sounds plausible; I'd say the insulation /packaging becomes a significant faction of the cell mass at the 2.5 mAh size.

We'll have to downsize from microcars to nanocars Image

Works out to 36 Joules.
Given that a 10F cap could easily do the same job you would only buy the battery for the size and voltage consistancy.

Still if they started stacking in larger formats and had 10k+ cycles that's a pack that is in for the life of a car!
So the short answer is NO but the long answer is YES.
