Wouldn’t mind not having lithium in my pocket. And in ears for that matter (earbuds)

Interesting. It will also cause geopolitical changes because lithium is a rare earth mineral. And Sodium is obviously abundant.

This sounds still very academic though and be aware that these things take time to industrialise. Also sometimes it doesn't pan out in the end.

The fire hazard might be reduced but of course any battery storing so much energy in a small place has some kind of hazard. Hopefully the runaway fire providing its own oxygen is solved here though, this is the main reason it's so hard to put the lithium battery fires out.

This could potentially open doors for short-haul e-aviation. Very interesting

In addition to the article’s stated benefits of faster charging than Li-ion, less temperature sensitivity, and lower propensity of thermal runaway, does switching to sodium also potentially address a raw materials problem? (Imagine if desalination could be made ecologically viable by harvesting the waste sodium for batteries…)

And what’s the downside? More complex chemistry to make the cathode?

Fun fact, sodium metal has also been used to directly make wire. It has some compelling properties.
