"The new material provides an energy density...1,000 watt-hours per liter, which is about 100 times greater than TDK’s current battery in mass production. Since TDK introduced it in 2020, competitors have moved forward, developing small solid-state batteries that offer 50 Wh/l, while rechargeable coin batteries using traditional liquid electrolytes offer about 400 Wh/l, according to the group. "
TDK are claiming this new solid state battery provides "1000 watt-hours per liter"
Whereas for comparison a Panasonic Li-ion battery like a UPF496171Z offers 650 watt hours per litre.
So compared to competing Li-ion batteries, they're claiming a 50% improvement in energy density.
Was posted here just yesterday and is a far better article.
Normal lithium cells use electrolyte gel and metal sheets.
Basically think ceramic vs electrolytic capacitor.
Article is also pretty worthless because it also implies that's the actual factor of improvement.

Most batteries found in laptops can be found in 200-600 Wh/L depending on the exact chemistry. TDK is claiming 1000 Wh/L
I would love to see any improvement on this front.
