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.

    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.
