CelloMomOnCars, Everyone is talking about building very large #batteries for energy storage, for when the sun doesn't shine or the wind doesn't blow. Turns out, that is the most expensive solution. There are faster solutions that yield money.
"Lovins and many other #EnergyEfficiency experts have spent decades pointing out that an integrated system approach that focuses as much or more on consumption than supply will be so much cheaper than the current approach focused on supply."
Olly42, Lithium-Free Sodium Batteries exit the Lab. 🔋
Natron Energy, a pioneer in sodium-ion battery technology, has officially commenced mass production of its lithium-free sodium batteries in its Holland, Michigan facility. Offering an alternative energy storage solution with benefits such as faster cycling, longer lifespan, and safer usage compared to lithium-ion batteries.

kirk, Really happy to share that our open-source battery project has the support of NLnet/ @NGIZero !!
https://fbrc.dev/posts/NLnet-funding/
With this catalytic funding, our small collaboration to develop an open-source flow battery for stationary energy storage can further develop. We're planning on finalizing our small-scale benchtop kit (for R&D/educational use) before going to a larger cell design.
Very grateful for their support and belief in the project.
kirk, New blog post: set up a website for our open-source battery project at https://fbrc.dev
Details and rambling here:
https://dualpower.supply/posts/setup-FBRC-website/It's in the very early stages (as is our project) but happy to receive any feedback folks might have.

CelloMomOnCars, "#Batteries the biggest player again as renewable records smashed in #California, reach 156 pct of load
Last week battery storage became, for the first time, the largest supply source in the evening peak of what is one of the world’s largest grids. On Tuesday, it discharged more than 6 GW for the first time, providing up to a 25 per cent share of supply, and was the biggest provider on the grid for two hours."
CelloMomOnCars, "The records continue to tumble in #California, one of the world’s biggest state grids, with #BatteryStorage playing an increasingly dominant role soaking up solar in the middle of the day and shifting it to the evening peak, where it is now regularly the biggest single supplier."
CelloMomOnCars, "#Battery storage in #Victoria continues to displace gas as a provider into the evening peak, with more than 200 MW of battery output on Saturday night, and zero from the state’s peaking gas generators. Battery storage often supplies more into the evening peak than the gas generators, particularly at lower peak prices."

sfwrtr, Want some #verisimilitude for your post-apocalyptic story? Four years after the pandemic started, 7 out of 7 examined #battery-powered candles had burst batteries. 3 out of 7 had destroyed circuitry and were irreparable. I restored four of the candles to working order with a lot of cleaning and scrubbing, but of course they required fresh #batteries.
Takeaway: Nothing battery-powered left for four years will work when found. Much of it will be destroyed.
Bonus: Gasoline has a shelf life and may be useless in 6-12 months. Sorry, no verisimilitude in Mad Max.

It's amazing what happens to bicycle tires with 5 years of no use. From experience. Conventional 10 speed bike. Better quality may last longer.

ncrav, Was checking out some reports about the DRC and found this piece by the NPR. Just another "detail" western organizations pushed under the rug when talking about clean energy solutions.
Cobalt is mined using basically slave labour. The mines polute both soil, air, and water. Although nowadays we have a lithium battery type (LiFePO4) without cobalt, it's still used, and also in e.g. alloys and gas turbines.
ncrav, (edited ) Note that lithium itself doesn't fare that much better in terms of environmental destruction: https://www.euronews.com/green/2022/02/01/south-america-s-lithium-fields-reveal-the-dark-side-of-our-electric-future
It's going to be hard to develop cleaner alternatives when companies can continue to destroy lives and continents for free to fulfill demand. We have some alternatives (like sodium) that are way cleaner in terms of pollution and blood, and others that can be made cleaner like hydrogen fuel cells. And if the solution mentions profit, then they're not trying to solve anything.
aud, … ummm, is this battery bulging??? I’ve never had that happen so I’m unsure what to do here. It feels… a lil spongy. Do they have a slight foam barrier orrrrr
#battery #batteries #bulgingBattery #laptopBattery #laptop #mobileDevice
aeva, @aud to store it while you figure out how to recycle it, put it some place cold where it's unlikely to get pierced or crushed. I had one inflate that started pushing out the track pad in my laptop for the better part of a year or so before I realized what was going on. iirc @mym put it in a stock pot on a shelf in our back room (which is quite cold typically) at our old place.

danie10, @MartinaNeumayer they did state this is mainly for those batteries that have just discharged below a certain point.
MartinaNeumayer, @danie10 I didn't read the entire thing. I just know that from my own experience and time when I was working in the service repair shop. Btw.. some of them shouldn't be even opened.

glynmoody, New #gas power plants needed to bolster energy supply, PM says - https://www.bbc.com/news/science-environment-68538951 environmentally and economically illiterate: the backups we need are #batteries, not #fossilfuels
KraftTea, @glynmoody The UK is so bad at "green" energy, it needs to decarbonize 10% of it.
I do not like nuclear, but burning carbon fuels fouls the air, and kills quite a few people, very reliably, every year. I hate gambling, but the odds of nuclear killing you are likely lower.
Wind is the best green source, but needs to scale tenfold. Unlikely, due to nimbies.
Let's hope for fusion. Or something like improved hydrothermal.
...because UK energy policy is a hot mess.
glynmoody, @KraftTea it certainly is...

kallemp, @danie10 Ni-Cd coin cells were available. I am not surprised that Li-Ion is also available.
Usually the rechargeable cells were provided with PCB terminals because they were supposed to last the life of the product.

'A Northwestern University-led team of researchers has developed a new fuel cell that harvests energy from microbes living in dirt.... the researchers used it to power sensors measuring soil moisture and detecting touch, a capability that could be valuable for tracking passing animals.... Not only did the fuel cell work in both wet and dry conditions, but its power also outlasted similar technologies by 120%.'

Heliograph, "Conventional flow batteries pack very little energy into a given volume and mass. Their energy density is as little as 10 percent that of lithium-ion batteries, due to the amount of material an aqueous solution can hold. There is only so much salt you can dissolve in a glass of water.
Thus flow batteries have been too bulky for most applications so far. To shrink them enough to fit in electric vehicles, you need to raise their energy density to that of #lithiumIon #batteries.
One good way to add capacity is with nanofluids, which hold nanoparticles in suspension. These particles undergo redox reactions at the electrode surface similar to how the dissolved ions react in conventional flow batteries, but the nanofluids are more energy dense. Importantly, the nanofluids are engineered to remain suspended indefinitely, unlike other suspensions—for instance, sand in water. That indefinite suspension helps the particles move through the system and make contact with the electrodes. The particles can compose up to 80 percent of the liquid’s weight while leaving it no more viscous than motor oil.
A next-gen system should have 5 times the energy density of present Li-ion systems."
nicod, French Qu'est ce que je peux faire de mes batteries 18650 que je n'utilise plus ?
J'en utilise 4 en rotation entre mon chargeur et ma vapoteuse, et quand elles ne tiennent plus la charge (au bout d'un an et demi à peu près), j'en achète d'autres.
Je garde les anciennes pour l'instant mais il y a peut être un moyen de les recycler ?
