New sodium-ion battery skips mechanical cooling with 97.9% efficiency
I’ve been hearing about these for a few years now. Huge if they work out at a large scale.

The 210Ah sodium-ion cells deliver up to 218Ah of discharge capacity.
WTF does that mean?

Either AI slop, someone fucked up the math for the capacity, or they’ve broken thermodynamics and are pulling power out of the ether.
First is most likely, 3rd is the coolest.

If only my other electronics operated at 104% efficiency.

It’s the world’s worst ZPM

Possibly the same as 1kg rice ±50g?

Badly written, i suspect the cells are speecified to have about 210ah and a real test showed 218ah capacity. That would be pretty normal since you always have manufacturing tolerances. But i think in a good article they would have worded it better if thats the case since not all of these batterys will do 218ah.
