Thread for new battery breakthrough PR releases

Damn... thanks bowlofsalad... I did a quick scan before posting, but obv missed that other thread with the same article.

Beautiful!

The potential energy density of a well designed nano-scale battery structure is immense. In practical applications these advancements could provide the range consumers demand with the weight reduction and incredible reduction in required materials that product manufacturers are looking for.

Do keep in mind that as energy density increases, and weight and package size decrease, the potential for a rapid exothermic event goes up as well. This also follows the package size decrease and the drive to expand this new tech into previously unfeasible markets, such as consumer electronics, where a higher incidence of use could be followed by a higher number of disastrous occurrences.
 
didn't read the link, but I've read other stuff about this

the cells have a 10 times higher C rate for a given size, but the same energy density as old cells


so you can push/pull power into/out of them 10 times faster... but they still have the same ah capacity as the old cells
 
New lithium-ion battery technology that is 2,000 times more powerful than comparable batteries
Researchers at the University of Illinois at Urbana-Champaign have developed a new lithium-ion battery technology that is 2,000 times more powerful than comparable batteries. According to the researchers, this is not simply an evolutionary step in battery tech, “It’s a new enabling technology… it breaks the normal paradigms of energy sources. It’s allowing us to do different, new things.” .... In short, this is a dream battery.....more

Anyone actually read the paper this article with an unlabeled chart is based on? Sounds like one in an endless string of "We think on paper something is possible... we don't know if we can build it, if it is scale-able, what the life expectancy would be... but hey, let's announce that it is 2000 times more powerful than what has actually been built... oh, should we also state that it'll be at a tenth the price?

Can't argue with that. I'm sticking to my A123 AMP20 battery - its working great! But when I need a replacement, I'm hoping greater energy density, power, faster C-rate, and longevity in cycles. This just goes to show that there are many Universities who are investing in battery-tech, that strides are being made, and sometimes they are phenomenal.

FYI, A123 is an example of a company that got out of research and into actual manufacture, complete with factories and output, but that did not make it in the open market, having declared bankruptcy. There are lot's of hurdles before a battery technology ends up the hands of the likes of us. Sometimes that can be an advantage (as I got my AMP20 cells on the cheap as recycle of unused batteries). Its academic research that is driving the equation in our collective favor. Why knock it?
 
Maybe it would have helped if they had been willing to sell their batteries to anybody.
 
Don't these guys share a cubicle with the hydrogen car team? There's been talk for awhile, oh yeah, sounds great if only. . . .

This is what we need, it's so tempting to believe someone can give it to us overnight. This and every other article I've seen about it has always been vague talk. The Urbana-Champaign equivilent to the Iranian time machine. Wonder what the investment dollars they're looking for are.

And yeah, 'Enough energy to jumpstart a car battery' is vague, depends on the size of the engine to be cranked and just how dead the car battery is. If you could do that with a battery the size of a credit card, oh my. Doesn't it just set you imagining something that they haven't actually built yet.
 
It's all about the plate surface area, and getting them closer. The best designs interlock like putting two combs together, although never quite touching, of course. The size of the bristles is what many call nano tech. Material science rather than using formers. Although some are building up layers on polystyrene, and having some good results too.


Do we have any 'speed charging' threads? It seems RC lipo has a great C rating to exploit. Fast charging is what makes fuel stations useful to electric vehicles. When we can charge up in 5 mins, we can start realistically planning fuel stop's on route. Extending range in a whole new way
 
hold off buying those PV's yet again... :roll:

R. Colin Johnson 4/11/2013 05:11 AM EDT said:
PORTLAND, Ore. — Researchers at Ohio State University (Columbus) have devised a new method of depositing germanium in atomically thin layers, boosting its performance 10-times over silicon -- making it an easier-to-fabricate alternative over other next-generation materials like graphene. "We have been able to fabricate a germanium analogue of graphene -- monolayers which are terminated with hydrogen just like graphane materials, but which are much easier to fabricate," said professor Joshua Goldberger at Ohio State. "In the process, we also converted it from an indirect bandgap to a direct bandgap material, making it suitable for optical applications as well."Goldberger claims to have for the first time synthesized millimeter-scale pure crystalline lattices of hydrogen-terminated germanium (GeH) from the topochemical deintercalation of CaGe2, which he describes as a layered van der Waals solid analogous to terminated graphene (CH). Goldberger has dubbed his material "germanane" to liken it to the monolayer version of graphene called "graphane." Beside being based on germanium instead of carbon like graphene, the biggest difference between the materials, is that germanane has the potential to be more easily grown using convention semiconductor fabrication equipment than graphane. He predicts that the new material will be useful in fabricating next-generation optoelectronic devices and advanced sensors, since calculations predict that its electron mobility will be five-times better than bulk germanium (10-times higher than silicon) with a bandgap of 1.53 eV (slightly higher than gallium-arsenide) Graphene researchers have already demonstrated that the electronic properties of semiconductor monolayers can be striking better than those of the bulk material, spawning numerous efforts to create functionalized monolayers of other bonded crystal structures. Higher carrier mobility is achieved by virtue of the ultra-thin topologies, but by terminating these monolayers with ligands for specific applications, the ultra-thin materials can also be made far more sensitive than bulk material for sensor applications

this wuz originally its own thread to document germanium development but some mod with a ouch o' the ocd stuffed it in with batteries.
 
Hi All,

News of another battery breakthrough discovery.

http://www.bbc.co.uk/news/technology-22191650

here's hoping!

Cheers

While innovation and advancment is always good to see, i still get the feeling of 'if i had a dollar for everytime...'

Id love to see sometging actually come to market with even half the claims of some of these announcements, id pay through the nose for something with 3+ times the energy density of lipo! Best though to just keep an eye on the hobby market, as thats exactly what they want too... So they tend to snap up the best tech right away

I second that. I theorize that battery density, compared to the efficiency of most cars, needs to be around a mere 9 mj/kg. Sadly, these packs aren't coming over the horizon tomorrow.

p.s. Spell checker rocks.

I worked it out a while back, and came up with energy densities about 3x what lipo has now. it was based on current tech is around 1/9th the energy density of petrol... so given that electrics are roughly 3x the efficiency of ice's, they'd need just 1/3rd the energy per km, and thus 1/3rd the energy density. probably oversimplifying it though, as this would mean that you'd get the same range as a petrol car with a battery about the same size as your fuel tank, when batteries can take up far more space than that without issue.

I'd still love to see some 10+C rated bats with 3 times the energy density (both volume and mass)... but hey if were gonna talk pipe dreams I want a singe cell 130V 1000ah battery the size of my thumb that can be cycled at 1BILLION C. :mrgreen: :mrgreen: :mrgreen: oh, and available for $2.50 delivered, including shipping. Also every 10th one comes with a Russian supermodel to hang around and do your cleaning...

It can be done, mate. The trick is to store energy with zero mass. Hard to do, you say? Well that's what all EM radiation is, but then the problem with the C rate is that's the speed of light :shock:

So, can we bottle light? Turns out, yes now we can. Indeed, scientists have recently succeeded in stopped light completely, suspended in a medium modulated with a laser containment system. Researchers now able to stop, restart light. :idea:

[youtube]-8Nj2uTZc10[/youtube]

So the scheme for the "light battery" is a box full of frozen light, with a solar cell at the end to tap the power as light is released. Infinite storage? Probably not, but pretty damn high capacity, and best of all it weighs exactly the same full as it does empty. Just an engineering question at this point, the science exists. :twisted:

It should also be no problem getting that billion C rating, since you can theoretically release all the energy simultaneous (which is an infinite C rate). Max power is limited by melting your solar cell, but again that's just R$D. The energy storage capacity is there. :wink:

what are your opinions on this? this type of chemistry and system
 
It's different, if I understand it correctly. Unless they designed this type of battery with several form factors, I think it might be slightly harder to do anything with it other than utilize it in a proprietary system. Some of the pictures looks like the pack sizing might be easily modular, but that is hard to be certain. If it had all the values of something like lifepo4/a123 with a significantly better energy density, what is there to think about? I'd gladly use the swap system if it wasn't coming to me at a heavy cost.
 
About 30 years ago, every Japanese car makers, big and small, experimented the chemistry. Zn-air, Al-air few other metal-air batteries. They spent millions after millions dollars of money and years of R&D. Soon after, they found the chemistry have an excellent energy out put and cheap to manufacture (compare to other chemistry), however, they found the acceleration of the car (EV) are not good at all. The batteries are excellent for constant current draw but it does not take the fluctuation very well. So they tried to put another battery (Pb, Ni-cad etc) in parallel, used as an accumulator, to compensate. It is also hard to shut down, once after activated. When the car is not moving, it suppose to stop the chemical reaction but it doesn't. After many years of test drive. They concluded it's not worth any more of R&D and stopped all together.

But I think I'll wait for the Aluminum Ion battery to catch on. Like the Mac Powerbook uses. 3 valance electrons, so 3 times the power in a single battery the same size as well as charging 3 times quicker. The military has indeed DEVELOPED high capacity aluminum super batteries, but they have problems that keep them out of use, such as they can rot pretty darn quick. But they'd turn your 10 mile ebike into a 500 mile bike,, if in fact they can physically survive long enough.

"Low power, 30 seconds, on high, add a little salt, a WHOLE bunch, don't be stingy, that way when you taste it, I don't recommend tasting it, it'll be all SALTY!" Cracks me up.

Sounds like it's time to start collecting cans, that'd be a lot of cans. He was wise to mention not breathing aluminum, but you really don't want to breathe much other than clean air. Use a respirator when doing things like cutting and roughing up surfaces.

I imagine there are better ways of doing this that could produce far more surface area of aluminum.
