Oohhh, experimental groundbreaking paradigm shifting revolutionary battery design article #3646263859!
Let’s see if this one isn’t total bullshit like the 3646263841 ones before it!
Seriously this is getting ridiculous, I’ve seen these some literally 40 years ago, 99.99% is bullshit, and now I’m seeing literally over 5 new articles per week.
ITS BULLSHIT.
Call me when there is an actual battery based off peer reviewed research that has been successfully tested in production systems by at least 5 major companies. Until then, BULLSHIT.
it’s more of continuing series of AI hype
A few years ago I completely checkout out of all the future tech hype. A million videos and articles about the next big thing and nothing ever comes to fruition.
Call me when there is an actual battery based off peer reviewed research that has been successfully tested in production systems by at least 5 major companies.
While everybody was busy writing bullshit hype articles, we actually got a real revolution with the sodium-ion battery, which you can buy today. It won’t replace Li-ion in terms of energy density, but it’s much more robust, cheap, handles low temperatures, deep discharge and much more charge cycles, making it ideal for off-grid-storage.
I really wish we had tech news that just reports on stuff that’s tested and available for purchase. Things do actually keep improving, but it’s completely drowned out in all the other hype.
That was kind of my point.
I’m sure every now and then we get something great but pretty much all large tech content providers have fallen to pointless screaming fluff bullshit articles, every. single. day.
Actually, make that all content providers. Tech or not doesn’t matter.
And it’s more ethical and environmentally friendlier than Lithium-Ion, right?
Norway has just started a deep sea excavation for cobalt and copper which as I understand (I’m clueless) can be omitted from sodium-ion batteries. The excavation is roughly of the size of equador and will take place in an area that may contain previously unknown lifeforms and critically endangered eco-system.
A paragraph of an article seems to show their non-chalance regarding the ecosystem impacts and unknown side-effects:
“The Norwegian government recognizes that it can’t be sure any mining would be sustainable—it’s not been able to determine the likely environmental impact of extracting minerals in its waters, nor exactly what minerals are there to be found. “We do not currently have the knowledge needed to extract minerals from the seabed in the manner required,” says Næss.”
These are the guys whose grid runs on 99% hydropower but they keep drilling for fossile fuels and now rare earths to export them and in addition are still hunting wales.
So to summarise: I’m very happy that there seems to be an eco friendly battery where its main component is the overambundantly availabe sodium. And the short wikipedia entry seems to reflect, that it’s a more simple tech.
And then people bitch because That news outlet only reports on decades old advancements. It astounds me that supposed innovation focused people are so short sited and the community just laps up all your shit like a bunch of hogs chasing their last meal. Get a grip and go fuck yourselves, the whole lot of ya.
What about solid state batteries that can charge in 2 minutes instead of one hour? And have better capacity and a longer life?
As soon as they figure out how to actually mass produce them at an affordable price, and fix the swelling issues during high charging a currents, they’ll be available.
this article is about changes to solid electrolyte only, you’d know that if you read the article. these have less conductivity ( = lower power density) tho
And have better capacity and a longer life?
it took 9 months of real lab work by real material scientists just to make it work, things like dendrite formation or swelling aren’t part of this optimization (well at least AI stage), the linked preprint doesn’t even mention dendrites once
you’d know that if you read the article
Oof. You got me there lol.
I read the article and this one line stood out.
It stood out because half of what Murugesan would have expected to be lithium atoms were replaced with sodium.
This isn’t new I think. Sodium-ion batteries were already known. Maybe there was still dendrite formation and this recipe might reduce or eliminate that? We’ll have to wait and see.
In any case, if it can drastically reduce lithium usage that would be good progress.
OK, but is the energy density comparable?
“His team built a working battery with this material, albeit with a lower conductivity than similar prototypes that use more lithium.”
I do know that because of Ohm’s law, this directly translates to less available current than conventional electrolytes.
Yeah, batteries internal resistance is a huge factor in their usability and the speed they charge.
Especially in the modern day where a lot of their use is towards high amperage applications like cars.
People need to understand tho, Lithium batteries are usually only about 11% lithium, Lithium Ion batteries are mostly Cobalt and other metals. So at most you’re replacing 6% of a batteries total mass.
Mostly cobalt is also not accurate. There’s a small part of cobalt in some batteries.
Other like LiFePo are cobalt free.
All energy density is comparable. That’s what makes it energy density.
They designed and built a battery that uses up to 70 per cent less lithium than some competing designs.
This is probably a way of phrasing that means it’s up to 70% less than the absolute most lithium-requiring designs that few/no one uses, and probably only marginally better than most designs actually used. Since they’re very vague about it, I will be sceptical and assume it is way less revolutionary than the headline suggests.
Also, AI would have just sped up an existing plan they had to try new approaches because AI doesn’t create new ideas or think of things out of nowhere.
If you tell AI to do things within a certain range and it gives you results then AI came up with a design as much as google came up with search results when you put something into the search bar.
Not even close to true
Do you think AI just does things unprompted?
No one said anything about unprompted
😏
That’s not true at all. AI can in fact generate novel techniques and solutions and has already done so in biotech and electrical engineering. I don’t think you understand how AI works or what it is
Name one that wasn’t just doing the thing it was told and the users being surprised. You know, the same way that people are surprised when research has results they did not expect using other approaches.
It’s a weird way of asking this. Of course it’s going to do what’s told, the alternative is that it, out of the blue, spits a battery design for no reason. If it were to somehow find a way to make batteries with less lithium in a way that never did before, isn’t that an unexpected result using other approaches?
This is not general artificial intelligence, everything we have is narrow AI, focused on solving one specific problem, for identifying birds to understand instructions between drugs.

Yeah, that would be coming up with a battery design.
I think maybe people are running into a misunderstanding between LLMs and neural nets or machine kearning in general? AI has become too big of an umbrella term. We’ve been using NNs for a while now to produce entirely new ways to go about things. They can find bugs in games that humans can’t, been used to design new wind turbine blades (even made several asymmetrical ones which humans just don’t really do), or plot out entirely new ways of locomotion when given physical bodies. Machine learning is fascinating and can produce very unique results partly because it can be set up to not have existing design biases like humans do
And the nature of computers is that they are magnitudes better than humans at brute forcing. Machine learning can brute force (depending on the technique, it can be smarter than brute forcing, being more efficient) test many many many more designs and techniques than we could manually do. Sure it’ll fail many times, but it’s just a numbers game, and it can pump those numbers. It’ll try a lot of weird and unique stuff we wouldn’t even think to try, with varying degrees of success.
It can apply existing concepts in ways we haven’t thought of. AI has been used for exactly this thing for years in chemistry. When given constraints (less lithium) and parameters (with this much capacity) it can try permutations of various designs that theoretically meet those conditions.
Yes AI is overhyped, yes it’s often exaggerated by news sources, but that doesn’t mean AI is a non-invention or something. It’s a long way off from any of the lofty goals that are often thrown around by tech ceos, but that doesn’t mean it’s useless.
It can apply existing concepts in ways we haven’t thought of, like people do. AI has been used for exactly this thing for decades in chemistry. When given constraints (less lithium) and parameters (with this much capacity) it can try permutations of various designs that theoretically meet those conditions.
We have had weather models, astronomical models, and all other kinds of computer based prediction methods that do multiple permutations that theoretically meet conditions. AI is just another step forward by doing better pattern recognition and identifying relationships with data based on design choices. All of the chemistry findings came from the system being designed to try things they would not normally test for because testing is expensive and AI can run simulated tests faster and cheaper.
My point is that saying ‘AI came up with’ is 100% inaccurate phrasing intended to trick people into thinking that AI is intelligent instead of just being a very complex tool used to do things we already do faster. It allows for trying more permutations and more pattern recognition, but is just another approach to existing computer models that have also identified things we did not expect. Computer models used to identify starts with planets, but we don’t call those intelligent because they aren’t being sold as something they are not.
Your first comment my first thought was how does this have any upvotes. Thats super wrong
Top notch comback with this comment, i still cant agree with the original wording, i do recognize your point and agree with yoiur sentiment. Its a tool first and foremost.
Ah, I see what you’re saying. Yes the recognition for these advances should be with human programmers and engineers who are configuring the software and making the models for testing. You’re right I can definitely see why that distinction is important and the media should be making clear that the AI isn’t just turned on and magically works it all out on its own. It’s computational resources being directed towards a task, the models it works within are setup by professionals and the discoveries it finds are interpreted and made useful by those professionals.
The media is just parroting what the companies that want to sell AI are saying. They suck at reporting anything technical or scientific for sure, but they didn’t come up with this on their own.
you would know that if you read the article. they replaced part of lithium in electrolyte with sodium, so that they can use less lithium. the problem is decreased ion mobility ie less power density in real life terms.
Baker and Murugesan both say that lots of work is left to optimise the new battery.
bet
i’m gonna mostly ignore this finding because it sounds like extension of AI hype. real lab work is still absolutely critical in order to make it work
Not all batteries even use lithium. So why not just go with 100% less lithium, if that’s the target metric.
SLA doesn’t get enough love. It’s still the most reliable battery type in adverse conditions.
Also, lithium is of pretty low concern when it comes to the materials in current cells. Stuff like cobalt and nickel are more critical and would be larger news.
LFP batteries are both nickel and cobalt free, and are being used in production cars right now (e.g. Tesla model 3/Y standard range options). That technology has long arrived.
Yes, also Lithium Manganese Spinel cells have been around since 1996 and also don’t contain any nickel and cobalt. This is good but many vehicles and devices still use NMC and NCA due to the better specific energy density which is where LFP is limited (but can output more power and is much safer). Tesla (and every EV manufacturer) compromises on the battery depending on what chemistry they use, where if they could reduce the need for expensive metals while maintaining specific energy it would be pretty newsworthy.
I hate those sensationalist titles that portrait AI as if some sort of sentient being, and not just a tool the researchers used. The secondary title should have been the main one.
what, is the thumnail image
This post title is pretty bad. Even the news article says “Scientists use AI [read: machine learning] to [come up with new battery idea]”.
"Sure Dr.battery, I can create a set of instructions to create a new battery that uses less lithium for you!
Step one, use 70% less lithium.
Step two, drain the butter into a pan.
Step three, enjoy your new battery!
Remember: batteries can be dangerous and it’s always advised to check with your battery professional before making a battery."
It’s a real shame but I’m seeing this more often on all media sources. How do we combat these shitty titles?
Surely on Lemmy we have some power? I’ve downvoted and moved on but is that really all I can do?
Lithium isn’t the hard part, it’s cobalt. I hope they can look at decreasing cobalt next, or maybe using a chemistry that eliminates it entirely.
