I have not seen them offered as cheaply as is mentioned in the last article. Nothing like. They were about £3 each on ebay when I looked the other day.

July 7, 20241 yr At present, sodium-ion cells are almost 50% as energy and power dense as lithium-ion cells, meaning that a pack of equivalent performance will be around 200% larger/heavier.
July 7, 20241 yr "UChicago Prof. Shirley Meng’s Laboratory for Energy Storage and Conversion creates world’s first anode-free sodium solid-state battery – a breakthrough in inexpensive, clean, fast-charging batteries" https://pme.uchicago.edu/news/uchicago-prof-shirley-mengs-laboratory-energy-storage-and-conversion-creates-worlds-first During battery assembly the powder was densified under high pressure to form a solid current collector while maintaining a liquid-like contact with the electrolyte, enabling the low-cost and high-efficiency cycling that can push this game-changing technology forward. “Sodium solid-state batteries are usually seen as a far-off-in-the-future technology, but we hope that this paper can invigorate more push into the sodium area by demonstrating that it can indeed work well, even better than the lithium version in some cases,” Deysher said. If this is true, and it works, it could mean a revolution in battery technology. I used to think a few years ago that we were at the limits of the practical physics and chemistry of battery development. We were certainly not. Very clever people keep coming up with very novel ideas like this and we might soon see the back of batteries depending on the very scarce element we now depend on.
