Swiss researchers have developed a hair-thin sheet battery that can be charged in 1 minute, and they think can be scaled up to make batteries for phones and cars. (ethz.ch)

Did I miss what the energy density is for those batteries??

No, they don't provide any specifics about the capabilities of individual layers, but I would guess that they can customize the energy density of a solid-state battery by adjusting the manufacturing process.

They do say that they are only currently the size of a pinhead, so they are still in the proof of concept phase.

I see. It would be nice to at least hear a hypothetical energy density so we can get a feeling as to how good these new batteries would be.

I agree with you, but it sounds like the technique is an advantage because it works at higher and lower temps than standard batteries.
