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.
