I can only hope these can actually hit commercialization, unlike most new battery technologies that never leave the lab.
New sodium ion battery stores twice the energy and desalinates seawater

Finally a new one!
It was too quiet during the whole last year. But before, we had about 2 revolutionary new battery technologies every week.

Yeah I’ll take this seriously when it enters commercial service.

Desalinating water might be the best part. Usually, solar power has the downside of needing storage and desalination has the downside of big energy requirements. If you can do both at the same time, it’s a big win for dry climates with lots of sun

Sodium ion batteries have less energy density as opposed to Lithium ion (100-150 WH per Kg instead of 150-250). I’m curious how much these “wet” batteries improve that. The article doesn’t say.
Nonetheless, even if it’s not the new battery for your car, it could be useful as energy storage for the grid, storing green (solar) energy for the night, and desalinating seawater at the same time.

the strategy of retaining crystal interlayer water yielded a specific capacity of 280 mA h g−1 at 10 mA g−1, one of the highest capacities reported for SIB cathodes in literature.
BTW its worth noting how far this is from market. Currently these batteries are basically just jars with chemicals.

Fairly sure those units are milliamp•hour per gram which makes sense for energy density.
finalarbiter@lemmy.dbzer0.com 1 hour ago
mAh/g (milliamp-hours per gram) is a similar unit, but it’s missing the voltage term. We can do a little dimensional analysis here to translate between them. Power = Current * Voltage, so you’d multiply this (CurrentTime)/(Weight) value by the nominal voltage of the cell to get to (PowerTime)/(Weight). So it is essentially still a measurement of capacity, but in terms of current instead of power.
Phone batteries are often specified in units of Current*Time (e.g. milliamp-hours), but I’m not sure why.

We hear about a new battery chemistry like every week. Do most never get to commercialization?

One in ten of chemistries in the lab work in real world conductions. One in ten of those are cheap enough to consider production. One in ten of those can scale up to mass manufacturing. Most research works like that. You have to keep going until you hit jackpot.

They mostly these articles are showing new avenues for research. Most are deadends usually due to issues with production/scalability.
Sodium Ions batteries are coming to market, however the issue is that Lithium Ion are just improving faster and making it harder for Sodium Ion batteries to compete.

R&d on these I’m guessing takes a little while. And it greatly depends on what niche they fill. Like the poster above said these might have lower density. For applications that move, that’s not usually good. How sensitive are they to hot and cold? That could necessitate thermal management.

I think the real breakthrough will come when we will be able to make powerful microbatteries.

I think there were some nuclear button 1W decade-long batteries, from China if I recall

Not a new idea, although I don’t think that particular isotope has been used before.

It’s already an ion e.g. NaOH.
The compound, called nanostructured sodium vanadate hydrate (NVOH), delivered far stronger results when used in its hydrated form.

What are you gonna do with your 400 charge cycles?
