Other use cases would be where a car has some sodium batteries and some lithium based ones. The sodium batteries could serve most of the “wear and tear” of short trips, with a second smaller lithium back available to augment overall range which is not used as often.

This is a neat idea, but wouldn't solid-state lithium be far, far better for that purpose?

AFAIK SS lithium have huge price tag, at least for now.

Not really — portable batteries are already on the market and aren't that much more than conventional Li-ion.

Are they? Good to hear. However Samsung is starting mass production for EVs and they are targeting initially the most expensive segment. But let's see once they start producing them.

Sodium batteries are a lot cheaper, and the materials are easier to come by
