    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.

      LFP is a lithium-ion technology. You probably meant “worse than NMC”, which is another, older, higher density but less safe lithium-ion technology.

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