Grid storage only. But still cool

[–] mipadaitu@lemmy.world 78 points 3 months ago (1 children)

More grid storage means more capacity for renewables.

[–] Blum0108@lemmy.world 27 points 3 months ago

Exactly. Renewables plus grid storage is the way to ditch fossil fuels

[–] UnityDevice@startrek.website 19 points 3 months ago

You say that as if solving grid storage wasn't one of the most important problems humanity faces right now.

You will almost certainly see sodium-ion in cars. The Na batts already manufactured have a similar Wh/kg to Li batteries in EVs today. That's because Li has progressed further, and it takes a few years for new batteries to go into actual EVs. Manufactures don't necessarily use the top of the line batts, either, for cost or availability reasons.

If you feel a VW id.4 or a Hyundai Ioniq has sufficient range right now (or could have sufficient range if charging infrastructure was a better), then an Na batt will also be good enough. It'll also be cheaper. Those cars come off the assembly line with Li batts that are similar to the 160 Wh/kg that Na batts out of CATL were doing in 2021.

These will be useless for EV's, but great for storage. They aren't energy dense enough for what the EV market needs.

Samsungs solid state EV batteries are currently the only positive step towards EV replacement and production vehicles are set to start rolling out around 2027. They're supposed to be lighter, last more cycles, charge faster, more energy dense, and safer than current EV liquid lithium batteries.

The sodium ion batteries will be great for large scale solar storage and house/business solar storage. They should let someone build a solar powered house that could continuously run completely off grid without needing to use lithium batteries that would need replaced every 10 to 15 years.

I can't remember the name but I'm pretty sure some Chinese EV manufacturer has started to make EVs with salt batteries already.

[–] mysteryname101@lemmy.world 4 points 3 months ago

BYD. Seagull or the seal. Can’t remember which one.

Sodium ion batteries on the market right now are about the same weight density as lithium poly batteries from a few years ago. It takes a few years for a newly manufactured battery to find its way into actual EV models. That means the newer sodium batteries have about the same performance as batteries in EVs right now. They're also cheaper and are made of more abundant materials.

Don't write off sodium batts in cars too quickly.

Why not? From what I've seen, they're about 75% as energy dense as lithium, and a lot cheaper. So if the Chevy Bolt gets 200-250 miles range on lithium batteries, I'd expect 150+ miles w/ sodium-ion, which is plenty for my commute. If the battery costs half as much and lasts 5-10 years, I'd buy that to replace my commuter in a heartbeat. Give me a commuter at $15-20k w/ 150 miles range and I'll buy.

[–] KillingTimeItself@lemmy.dbzer0.com 4 points 3 months ago* (last edited 3 months ago) (10 children)

these batteries are a lot cheaper, and a lot more cycle resistant, which is what you primarily do for stationary storage, i think they're probably safer as well?

It would make some EVs cheaper, but they would have less range, and it's probably a little redundant considering you could just use less lithium ion batts instead.

Like the commenter said, we should be focusing on the solid state batts that samsung is fucking with, those are have REAL potential to be significantly better for EVs.

As long as the locals benefit and the environment doesn't get destroyed ( which polluters frequently get away with due to the Republican legislature, see https://en.wikipedia.org/wiki/2014_Dan_River_coal_ash_spill ) this is a sensible place to put industry. It is more stable environmentally than many other regions in the country where expensive industrial infrastructure is being placed (like the Southwest), has available labor for manufacturing, and is well connected to transportation.

[–] FenrirIII@lemmy.world 4 points 3 months ago

Everything bad you expect is going to happen.

Sodium-ion batteries are gaining attention as a potential alternative to lithium-ion batteries for EVs, mainly due to their cost-effectiveness and abundance of raw materials. Sodium is more readily available and less expensive than lithium, making it an attractive prospect for scaling up EV production.

I don't know why they said this — they really aren't a viable alternative for weight-sensitive contexts at all. Their density is only abut 60% that of Li-ion batteries, and that isn't even getting into solid-state Li batteries which are even more dense. If weight isn't an issue, like for home or grid backup storage, they're fine. For cars or bikes, not so much.

[–] drosophila@lemmy.blahaj.zone 20 points 3 months ago* (last edited 3 months ago) (1 children)

There is already a Chinese EV that uses a sodium ion battery, the JMEV EV3.

It's a tradeoff of range vs price. The EV3 only has 155 miles of range, but thanks in part to its sodium ion battery it costs only $9220 new. Which is a price that will probably drop even more as more sodium ion plants come online and economies of scale kick in.

EDIT: even if your commute is 40 minutes long, driving 60 MPH the entire way, that range is enough to get you to work and back using a little more than half your charge. Given that it's also generally cheaper to charge an EV than pump gas, and there's less maintenance costs, I think there's absolutely a market for such a car.

[–] n3m37h@sh.itjust.works 10 points 3 months ago

I'd be able to drive that to and from work 15x before charging.

[–] macarthur_park@lemmy.world 19 points 3 months ago (3 children)

The volumetric energy density is 60% of lithium ion batteries, but the energy density per kg is more like 75% since the batteries are lighter. Assuming that scales to the ev range, that’s probably sufficient for a lot of use cases.

[–] ColeSloth@discuss.tchncs.de 2 points 3 months ago (1 children)

EVs are already too heavy and wear tires out quickly. The upcoming solid state batteries are what will go into future EVs. Samsung is producing them right now and they're currently set to start going in higher end E vehicles in 2027. At best the sodium ion batts may be good for hybrids.

[–] SuperCub@sh.itjust.works 4 points 3 months ago (1 children)

You're forgetting that these batteries are going to be cheap because the compounds needed are readily available. This tech is not going to replace every lithium battery out there, but it's going to give consumers another, more economic choice vs lithium. Plus it's a safer technology than lithium.

Your explanation is valid for vehicles that have 100% of their battery be something other than Sodium based, and also have a use case that requires long or intermediate range. That isn't all use cases. Vehicles that drive a lot, but never cover much distance would still be valid use cases for 100% sodium. 100% Sodium Ion powered EVs started rolling off assembly lines in Dec of 2023. Alternatively 100% Sodium Ion could also be for things like fork lifts or Semi trucks that move storage containers from a cargo ship to a storage location within a mile and repeat this trip dozens of times a day.

Other use cases would be where a car has some sodium batteries and some lithium based ones. The sodium batteries could serve most of the "wear and tear" of short trips, with a second smaller lithium back available to augment overall range which is not used as often.

Unless we get to the point where we do battery swaps in cars instead of charging. Just pull the fusion core and pop in a charged one. If we can do it for propane tanks we can do it for cars. Run out of "gas"? Tow company can bring you either a full charge or a smaller battery to get you to the next swap point. Most likely this will start with cross country trucks, the owners can have swap points or drive out a battery for a truck that ran out early.

cool to see that we're finally getting local production of these things here in the US.

[–] Hexbatch@lemmy.world 13 points 3 months ago (6 children)

I’m going to assume the community gets poison while the factory cranks out batteries, and delivers few jobs or taxes?

I’m also going to assume the community recognizes this but hopes to improve their area with new education and other investment? Or a lot of people were bribed ?

Am I wrong ?

[–] chiliedogg@lemmy.world 17 points 3 months ago

A small town near out together an incentive package for a wind farm that was shopping itself around the country.

They imminent-domained hundreds of tiny plots of land from local farmers so a billion-dollar wind installation could go up without paying the farmers, and in return the city received $200,000 it used to paint a school, and the peoject it created a whopping 2 full-time jobs after construction was completed.

And the mayor acted like it was a victory.

if you think factories are bad wait until you find out what amazon gets away with. They can literally break fire code because nobody cares enough to do anything about having the worlds biggest retailer warehousing in your county/state.

[–] surewhynotlem@lemmy.world 4 points 3 months ago

Of course. The pork industry in NC is exactly the same. Tobacco as well.

NC has a strong Republican majority in the government with a fairly weak Democrat governor. They make bad decisions. I'm not sad I left.

[–] GeneralVincent@lemmy.world 3 points 3 months ago

Yeah, probably wrong. There's not a bunch of third party info on the environmental impact this factory will have, and no evidence anyone was bribed. If it makes you feel better, this isn't their first factory and I couldn't find any negative news about that factory either. Community leaders were supportive though, and a bunch of jobs were created.

I did find some articles about the positive environmental impact sodium batteries have from production, to relative ease of recycling, if that makes you feel better.

[–] potpotato@lemmy.world 2 points 3 months ago

An issue near me: a major plant is fined every time they exceed emission limits and those fines go back to the community.

Great, finally some Sodium batteries that are not made in China.

Hopefully this time NC's gridscale battery factory wont go bankrupt when the Russian oligarchs founders take the money and run. https://www.charlotteobserver.com/news/business/article167970747.html

"It’s facilitated in part by a Job Development Investment Grant from the North Carolina Department of Commerce, which gives cash grants directly to a company when it creates jobs and invests in the state."

I wonder if this makes it kind of like, although not equivalent to, a project labor agreement. I know North Carolina is a right to work state.

It would be nice for there to be union presence on a job this large. However small the chances of that may be.

[–] billwashere@lemmy.world 5 points 3 months ago (3 children)

How do you create gigawatts of batteries. Wouldn’t it be something more like gigawatt-hours of batteries?

Yeah, it's probably GWh, W and Wh are frequently interchanged.

Idk, sounds like another FoxConn lie to siphon off public funds and underdeliver.

[–] ChaoticEntropy@feddit.uk 3 points 3 months ago

Put up a shack, hire 10 people, pocket the remaining money, pay it to yourself in dividends and stock buybacks. Huzzah!
