They should be the default for solar installations and grid-level storage, but are too new.

They can also replace lead-acid batteries for many applications.

Lithium will still rule microelectronics and wearables, but all lower density stuff should switch to sodium.

That being said, for cold environments like Scandinavia and the US Midwest & canada, sodium ion works better in both cold and heat swings than Lithium variants that it might be worth the tradeoff in capacity because in the long cold months, the reduced capacity and performance of lithium chemistries would completely close the gap anyways.

Corpos suck ass and have no respect for their workers, but revenue is pretty useless for guaging a company’s financial health. Companies tanking and going out of business often have hundreds of millions until billions of revenue, while still being a hundreds of millions in negative. Kind of a different story than presented unless we know their revenue minus operating costs and if they have done investor money scams like stock buybacks.

Yeah my favorite electronics hobby supplies website has started to take 2-10 seconds to load. Still great service and the best selection of modules in my region though. They should really throw Anubis in front of it.
