So does pure lithium

  Which is exactly why I am wondering how sodium batteries will be any easier to manage.

    https://spectrum.ieee.org/sodium-ion-battery https://spectrum.ieee.org/sodium-ion-battery > Sodium batteries are also more stable and safe than lithium-ion. They have a wider temperature range, are nonflammable, and there is no thermal runaway—which can cause lithium-ion batteries to catch fire—under any condition, says Pouchet.

      Thanks for the actual informative link instead of the CATL press release others are linking. Sodium-ion batteries seem to have some very desirable properties over other rechargeable battery chemistries. Has CATL substantially improved the energy density? Half the capacity on a per-weight basis than Lithium-ion seems pretty bad for EVs. Halving the range of already barely-acceptable vehicles seems pretty bad. Maybe it’s fine for short-range EVs and hybrids, but the range is one of the selling points of the Bolt.
