Wikipedia lists lithium ion as having an energy density of 250–693 W⋅h/L

The article you linked says " energy density of 1,000 Wh/L, approximately 100 times greater than the energy density of TDK’s conventional solid-state battery."

Firstly 1000 is a bit suspiciously round. So is 100.

But assuming the numbers are rougly true, that would make the tech something like a 50% improvement on the current best lithium ion batteries. Which is plausible.

(100x is less plausible just because few chemical reactions store that much oomph)

So this is a 100x improvement compared to some rubbish battery that people weren't using.

Interesting to see how this turns out. Battery development has seemed painfully slow and one of the areas that’s really fallen behind in exponential advancement it seems. This sounds like a big step forward, but probably a ways out from mass production.
