    They’re currently bringing sodium batteries to market (as in “the first vendor is selling them right now”). They’re bulky but fairly robust IIRC and they don’t need lithium.

      If you’re thinking of the portable battery marketed as ‘solid state’ then that was a scam - a teardown revealed it was just lithium cells

        Nah, I’m thinking of sodium-ion batteries. That’s 1990s tech and is currently in use for grid storage. Several manufacturers are currently bringing car-ready Na-ion batteries to market and there seems to be one production car using them in China (a version of the JMEV EV3, which I hav enever heard about before).

        Now, Na-ion is still less mature than Li-ion and that Chinese car gets about 17% less range compared do the Li-ion version.
