Well it is exciting, but not for the reasons you think. More like a Michael Bay movie exciting...there is nothing practical about this design. Most of the cost will be safety systems designed to prevent the battery from being exciting and even then a crash will likely set them off. Pure Na-ion probably isn't viable and certainly isn't viable in a car. Maybe mixing in some Na into the Li-ion to stretch the small amount of Lithium but even then you are significantly increasing the volatility of the battery.
This isn't a practical step, its an act of desperation from people who don't want to admit that large scale electrification is a dumb idea. We electrified everything that made sense to electrify a half century ago.

Not even close. We electrify more and more as tech improves. Do you really think people were using electric leaf blowers in the 1970s?

You're saying: https://insideevs.com/news/786509/catl-changan-worlds-first-... ?

People say the same thing about Li-ion batteries yet they have proven to be significantly less likely to catch fire compared to ICE vehicles [1].

I'm very curious to hear why you think this. If nothing else, the 'situation' with the Strait of Hormuz would seem to have shown the importance of energy independence achieved through large scale electrification. Individually, I couldn't go back to an ICE car or even garden tools, they're worse in every way.
