Keep in mind that due to size these are only viable for industrial or utility grade storage. Not great for cars, devices, or probably houses.
CATL announces sodium batteries that cost as little as $10/kWh, a massive price reduction compared to the current average of $115/kWh for lithium-ion batteries.

The video says it’s 175 kwhr per kg compared to 185 for LFP that’s already used in some cars. Gold standard is Lion at 300. Volumetric is the same ratios.
So it’s usable in cars and absolutely immediately useable in homes.

Sodium batteries generally have poor round-trip efficiency. This won’t be game-changer for home or solar use unless CATL can solve that problem.

CATL first uses for the tech are literally car batteries. Your info looks to be outdated.
roofuskit@lemmy.world 3 weeks ago
Yes, outdated info then.

Aren’t the current models only about half as dense as lithium Ion?
Taking up twice the space for a tenth of the cost seems like a pretty acceptable trade-off for the house scenario
roofuskit@lemmy.world 3 weeks ago
Yes, it’s a great trade off, for particular applications.

Could be used at your house for solar power backup during the night?
WhiteOakBayou@lemmy.world 3 weeks ago
Yeah, just double or so the amount of space you’d need for lifepo4. Good if you have some space

Wake me up once its really for sale to normal people.

Where are they getting batteries for $115/kWh? Going market rate for LiFePO3 seems to be at least 10 times that.
DrunkEngineer@lemmy.world 3 weeks ago
I don’t know about LiFePo3, but LiFePO4 prices are dropping to the sub $100 level.

Not just that but they’ve also got the Choco-SEB modular battery swap thing going. 2min battery stops to full charge.

I don’t have a YouTube account and my pihole ad blocking gets me bkocked, is there an article it references? Also, what’s the kWh to cubic feet/meters ratio compared to current lithium ion?

The author posts transcripts of his video. Here is this one.

Same price, bigger profit margins.
