UPS batteries are something i don’t understand either. Why have they not changed with all the new tech we have now? Is it just still made of the best chemicals for their use and to then be recycled or something?
cmnybo@discuss.tchncs.de 49 minutes ago
UPS batteries need to be fully charged all the time. Lead acid batteries like to be fully charged. Lithium batteries need to be stored around 50% charge to have a long lifetime.

There are newer LFP portable batteries with <10ms UPS switch times that charge quickly and have much longer battery life’s, and LFP cells don’t degrade the same when kept at 100% like other types, although you should still cycle them a few times a year.
Bluetti makes some, the elite series has their latest UPS features. The non elite are slower and noisier.

So a 3 megawatt charger can charge 50 kWh in one minute. That’s some serious power.

Team expects, may be useful, could be used, prototype, are currently investigating and so on. Cool piece of technolgy, but no even mention when they’d expect that to be commercially available, if it’s even possible to manufacture in commercial scale. Like many other new battery chemistries and technologies, it shows promise and makes a good headline, but at this point that’s pretty much it.
suigenerix@lemmy.world 1 hour ago
To be fair, commercial long-life nickel-iron batteries are already being sold for grid storage. The main reason they aren’t used more widely is they cost more up front.
That’s ok, because they still cost less than alternatives over the full life span of the battery.
The risk is that the higher purchase cost required will likely be wasted as new battery tech surpasses it long before its life is over.
So for now, it’s all about weighing opportunity cost, tech lock-in, and early obsolescence

Well tbf this was a university lab which isn’t focused on commercial production but just trying to prove their experiments

The technology uses nickel and iron clusters smaller than 5 nanometers, meaning 10,000 to 20,000 clusters could fit within the width of a human hair.
By using these dimensions, the researchers increased the electrode surface area, allowing almost every atom to participate in the chemical reaction. This efficiency enables the battery to reach a full charge in seconds rather than the seven hours required by historical versions of the technology.

5nm nano fabrication will cost a fortune. this week’s cure-all battery.
TonyTonyChopper@mander.xyz 2 hours ago
Nano chemistry is entirely different from nano fabrication. I haven’t read the paper but most materials like this are made by mixing chemicals in a beaker and/or heating them in a furnace.

Just make one large enough to power my house for 2 weeks and let me use solar completely detached from the grid. I’ll put it on the side of my house.
HeyThisIsntTheYMCA@lemmy.world 1 hour ago
maybe in a shed off the side of your house? i would not want that fire attached to my structure in a failure.
ColeSloth@discuss.tchncs.de 43 minutes ago
It’s not lithium. This battery wouldn’t be a fire hazard.
solrize@lemmy.ml 2 hours ago
That’s doable right now pretty much, in that the cost of existing batteries is in proportion to the other stuff you’ll need.
ColeSloth@discuss.tchncs.de 38 minutes ago
The sodium batteries rolling out to market right now should be good for it. Just waiting for them to get out and into use for a few years to make sure their isn’t any immediate unforseen bugs. I just want a 30 year battery and not a 10 year, and time itself degrades lithium based batteries quite a lot. They can make one that will last over 500,000 ev miles, but don’t count on it doing it and lasting 20+ years.
DeuxChevaux@lemmy.world 4 hours ago
If it lasts 30 years, it will not fly with the industry and the concept of planned obsolescence.

Ooh, they’ll figure a way to make it clock out on the last monthly payment. One little chip will do, or just a few lines of code in the right place.

this is one of the bigger changes in battery tech i’ve read in a while. i’m curious about their beef aerogel tho. i have no personal problem using it (beef is going to be used, regardless, so ethically we should not waste the beef we’re producing) but i would love to see this battery tech become vegan. in part so i can calm the little part of my conscious, and in part so we don’t have to have an ethical debate about batteries.
Manjushri@piefed.social 21 minutes ago
Per the article they are working on that, whichever is good since cattle farming is not exactly eco friendly.
The researchers are currently investigating the use of other metals with this nanocluster fabrication technique. They are also testing natural polymers as more abundant replacements for bovine proteins to facilitate potential manufacturing.

the device achieves an excellent specific energy (47 W h kg−1) and superior specific power (18 kW kg−1)
I’m not familiar with this stuff. How does that compare to popular lithium batteries?
pageflight@piefed.social 4 hours ago
Looks like it’s more like NiMH than LiPo, but higher power than NiMH (which I guess lines up with their claims of charging super fast).
dual_sport_dork@lemmy.world 4 hours ago
Poorly. According to a random Wikipedia query, commodity lithium ion is 250 Wh per kilogram. So this is around 20% of that, according to the above.
“Excellent” may be in comparison to other byzantine specialty battery chemistries, but lithium ion remains resolutely enthroned.
cmnybo@discuss.tchncs.de 32 minutes ago
Nickel iron is typically used for off grid solar energy storage. Weight doesn’t matter at all since the battery won’t be moved. The most important thing is lifetime. Traditional nickel iron batteries last for decades and can be refurbished.

It might be cool for storing solar energy for your home, though. We don’t need to always carry the battery in every use case
solrize@lemmy.ml 2 hours ago
Home storage generally uses LFP which is around 170 WH/kg. 270 is NMC which is used in stuff like mobile phones where the trade offs are different.
empireOfLove2@lemmy.dbzer0.com 4 hours ago
Most li-ions land around 120-160 w/kg. So much poorer, but much cheaper on density
The specific power (power density) is kind of crazy though. I think most li-ions top out around 10kW/kg, any more and they will overheat and boil their electrolyte which usually leads to fire.
Eczpurt@lemmy.world 4 hours ago
I looked around and found that lithium ion batteries will range from 100-270 Wh/kg and up to 10 kW/kg.
So these particular batteries are quite an improvement, especially if they can beat lithium ion in cost.
socsa@piefed.social 2 hours ago
Just like with all of these headlines, it will not charge in seconds outside the lab without cryogenic cooling systems. Pack density is already largely limited by cooling systems, so everyone looking for faster charging and higher range should really be focused on superconducting tech more than cell chemistry

TankovayaDiviziya@lemmy.world 2 hours ago
It takes decades for innovative products, or seemingly useless ideas, to be commercially viable. That’s why the best response, when asked what is the purpose of doing research on seemingly useless topics, is to say “I don’t know, but I know it’s going to be taxed someday.”
