idk about that, the regularly cited reason Na-ion batteries are mainly being looked at for grid storage rather than vehicle applications is their bad Wh/l and W/kg numbers compared to Li-ion. the table in the Na-ion article seems to use “1000W/kg” without a source, and it shows lithium as being about a third of that even though the Li-ion article quotes figures up to 10kW/kg.
seems the editors of the two articles aren’t cross-checking eachother.

No, it seems like you have zero idea what you are talking about and are confusing W/kg with Wh/kg, which are very different metrics
Any info about energy density?
According to Wikipedia:
Looks like power to weight it much higher, while energy per volume and energy per mass is comparable to existing lithium ion batteries.

Googling says 175 whr/kg for catls sodium car battery that’s already in production cars vs 270 whr/kg for Tesla’s lithium.
Probably numbers for the raw cell though, not the balancing and cooling which could make sodium a bit more competitive.
W/kilo? Isn’t there a h missing or something?
one is energy density, the other is power density.
Aah, makes sense. I have seen soo many people confounding power and energy I thought it was the same here, my excuses.

No, the energy to volume is much less.
See, that’s what I thought, but the wiki article seems to disagree.
Or am I just misreading something?
I think they are testing Unigrid battery model 72173207 (terrible name). That is their 210Ah NCO prismatic cells.
I found this spec sheet. No definitive metrics, but someone else could do the napkin math.
That’s my daughter’s name. It was my great grandmother’s name.

CATL’s that went into mass prod sometime ago are 175Wh/kg.
