Is this the next big thing? Na. /j
Maybe they will make a potassium battery, K?
Maybe, but I want to see Uranium batteries go mainstream, how 'bout U?
Id prefer francium batteries, fr
Or gallium hydride? GaH.

I was hoping science would've gotten us to a tri lanthanside by now https://youtu.be/D8fHatctfRo
Sodium-Ion is already in production at CATL. Been for about half a year if I recall. It's slightly less dense than LFP but it's cheaper and promises to get cheaper yet.
You're right, they were making a pun about sodium's chemical symbol.
Not who you replied to, but thanks for explaining! I saw the /j but still didn't get it. I wasn't a good chemistry student...
The advantage of Sodium -Ion is that it's cheap, abundant, safe, and can cycle. It's mainly used where large capacities are needed. So industrial, grid scale, stationary types of storage.
Sodium carbonate is less common than lithium carbonate, but requires less processing
and way less dangerous.
And loads of charge cycles IIRC.
It's significantly less dense.
It's close enough to already be in use in some chinese cars. But definitely better for stationary use cases where density matters less.
One Chinese car.
It is considerably less dense. Those Chinese cars have only 20 kWh batteries
Sodium, not natrium.
I have a surprise for you...
Sodium is just what those weirdos call Naatrium.
