So does pure lithium
> 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.
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.
