Ah, these are the aluminum dust under pressure solid state batteries. I wonder how much pressure.

It does say "during assembly [...] to form a solid current collector while maintaining a liquid-like contact with the electrolyte".

After it's made it could be not under pressure at all.

I would think they'd need to keep the liquid like contact that's available under pressure.. But I'm no battery scientist.

Would be interested in seeing/reading more about it, don't have/want the subscription to read the white paper. Just seems like it could be somewhat like mirrors where it's important for the glass to be liquid at one point so there's no distortions and a strong bond but then once it's constructed it just sits there.

They have the pressure of reversing climate change so very high pressure

The decarbonization of our power grid will thankfully not be up to a single technology, but a multitude which are all seeing development simultaneously. Solar is reaching for better efficiency and less harmful creation, batteries of all shapes, sizes, and concepts are popping up from everywhere. It feels more like a race now than a slow decline into uninhabitability.
