    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.
