Good luck, corporations and governments will make even that increasingly hard with essential apps requiring tampering attestations from the big vendors, so you may need two devices.

Right, thanks. did not remember that name and searching yielded articles writing it like that so I went with it.

Early batteries had lower gravimetric energy density (145 Wh/kg) and volumetric energy density (330 Wh/liter) than LFP, but sodium-ion batteries have already improved since then.

OK, and where are the new numbers? 1% better, but still much worse than lfp?

Edit:a bit later they mention 175 Wh/kg and 10,000 lifetime cycles for some catl cells, that is not too bad, but still not great with lfp at about 200 Wh/kg which still is less than Lithium Ion NMC.

Even if they admitted that “later”, when exactly? After a night in the cold cell with a choice of being detained longer or immediate deportation if they admitted that?
