Sodium-ion battery

So a different material has to be used for sodium-ion battery anodes, and at least up until now anyway that's resulted in lower performance and lower energy density.

Fine for stationary energy storage, but heaven forfend we should see sodium-ion bespoiling a high performance electric vehicle, which is a shame because sodium is very cheap and very plentiful, with none of the ethical or geopolitical sourcing issues of its apparently higher performing periodic table neighbour.

And yet China's two biggest battery players, CATL and BYD, are now openly fast-tracking sodium-ion batteries.

CATL's sodium-ion cells are reportedly already crossing the metaphorical Rubicon into passenger vehicles.

And this is happening at the same time that lithium prices are once again reminding everyone how volatile and geopolitically awkward that supply chain really is.

Because the, this will pollute our environment as well.

So are sodium-ion batteries are realistic alternative to lithium-ion technology, and could they make energy storage more affordable? I don't know what's-

Hmm
