'Instantly Rechargeable' Battery Could Change the Future of Electric Cars (sciencedaily.com)
An anonymous reader quotes a report from Science Daily: A technology developed by Purdue researchers could provide an "instantly rechargeable" method that is safe, affordable and environmentally friendly for recharging electric and hybrid vehicle batteries through a quick and easy process similar to refueling a car at a gas station. John Cushman, Purdue University distinguished professor of earth, atmospheric and planetary science and a professor of mathematics, presented the research findings "Redox reactions in immiscible-fluids in porous media -- membraneless battery applications" at the recent International Society for Porous Media 9th International Conference in Rotterdam, Netherlands. Cushman co-founded Ifbattery LLC (IF-battery) to further develop and commercialize the technology. "Designing and building enough of these recharging stations requires massive infrastructure development, which means the energy distribution and storage system is being rebuilt at tremendous cost to accommodate the need for continual local battery recharge," said Eric Nauman, co-founder of Ifbattery and a Purdue professor of mechanical engineering, basic medical sciences and biomedical engineering. "Ifbattery is developing an energy storage system that would enable drivers to fill up their electric or hybrid vehicles with fluid electrolytes to re-energize spent battery fluids much like refueling their gas tanks." Mike Mueterthies, Purdue doctoral teaching and research assistant in physics and the third co-founder of Ifbattery, said the flow battery system makes the Ifbattery system unique. "Other flow batteries exist, but we are the first to remove membranes which reduces costs and extends battery life," Mueterthies said. Ifbattery's membrane-free battery demonstrates other benefits as well. "Membrane fouling can limit the number of recharge cycles and is a known contributor to many battery fires," Cushman said. "Ifbattery's components are safe enough to be stored in a family home, are stable enough to meet major production and distribution requirements and are cost effective." For the visual learners, Purdue Research Park has uploaded a video about Ifbattery's "instantly rechargeable" method.
Need more info, or else we're just spouting "if my car can start farting magic pixie dust it'll change the game" bullshit.
It's not a battery, it's a big ass capacitor that can take a huge charge instantly and let it our slowly.
Instead of changing my oil, I'll have to change my electrolyte.
Its got electrolytes!
It is a flow battery and the idea has been around for a long time.
The biggest problem is the nasty nature and quantity of chemicals used
"We need to ban gasoline powered cars in the United States "
So force everyone to buy a new car(s)? Electric and hybrid cars are still pricey and there is really no charging infrastructure requirement for people who routinely drive more than 100 - 150 miles from their home charging stations. Not to mention people willing to wait a significant amount of time while their vehicle recharges before continuing on their journey. How about sticking with the current path of replacing fossil fueled electricity generation infrastructure? Solar energy adoption is steadily increasing in the home and business markets. Transportation is only responsible for approximately 25% of green house gases. There are plenty of ways to reduce global warming just by targeting the other 75% sources for reductions. Oh and since methane is a significant source of greenhouse gases I assume you want to kill every cow and pig on the planet and outlaw beef and pork.
The new company named Ifbattery is still in it's infancy because they are seeking funding to begin making prototypes. So battery of the future is right because it's at least 10 years off at best.
Anons need not reply. Questions end with a question mark.
Agreed. We need to take desperate measures. Until we can find a way to get rid of all the CO2 in the atmosphere, humanity is going to be in grave danger.
Don't be stupid and lazy. We will definitely have electric cars that are cheaper to manufacture, cheaper to operate, and cheaper to maintain than ICE's in the very near future (this coming decade, guaranteed).
Any kind of mandates are just going to slow down the industry which is already on trajectory to exceed our ambitious desires.
YOU are not smarter than the people who are building these things, so stop pretending like you have more information than they do.
My God, it's Full of Source!

Yup, because of that and also because they have efficiency of about 1/6th of a vegetarian diet. Take that land of of use for corn and you can grow grass there, sinking (huge amounts of) carbon into the top soil.
Been working in the field of battery chargers or power management since I graduated with an EE degree in 1986, and I've only seen tiny incremental improvements. I have never seen any of the "revolutionary" claims actually work. Yes Li batteries are nice, but that was only have they took years of improvements to finally beat NiCad and then later nickel–metal hydride batteries. I'm not holding my breath.
Sooner or later car battery packs will be standardized. Then you will just switch the pack out at the station.
Charging of packs can be spread out through the day to even out load and the full packs can be used for load balancing the local area.
To crazy 300kW connector to your car to charge your 100KWh battery in 20 minutes.
Lemme guess, they solved all the hard parts and now all they have to do is commercialize it? Gonna do the typical 3 to 5 year prediction? Not holding my breath.

I would like to ban pornography because it's demonstrably terrible for people. And yet somehow, I bet you think I'm the weird one. Irony is ironic.
They want to replace the need for home charging, which is half way there already in the USA, with going to filling stations every week or two. I suspect that this will cost more, both for the infrastructure and to the user. It might be better for the occasional long trip but it sounds much worse for day to day travel.
I don't want to go to a filling station. I want to do my everyday charging at home.

That would be a terrible idea, there are many areas where electric cars aren't practical like Alaska. Industries such as trucking don't have electric technology available to them yet. Instead, a small tariff on gasoline a few cents per gallon, and a direct subsidy to cleaner cars would help to equalize the cost or tip slightly in favour of electric or cleaner technology. This would naturally cause many people to switch to the cheaper, cleaner options.

I thought that was a major feature expected for the Tesla Model 3.
Laws are rules for the court, but merely a bottom bar to hit for life. Think beyond laws in your actions always.
You're aware that the most environmentally sound thing you can do is continue driving your current car, right? Replacing it requires a huge amount of energy. The only time buying an electrical car makes environmental sense is if your current one is at the end of its useful life.
I think the idea is to just replace the electrolyte. The electrolyte gets charged while you're not there.

Oh no,not again..
I'll stick to using bloody great big lead/acid batteries,they have worked ok for a century for lots of things,they will still be around in 2117..
Anyone,what bats do they use in modern diesel/electric hunter/killer submarines ?
I bet it's good old lead/acids...
I mean, come on, all you need to do is read the summary to know that this is a flow battery - you recharge it by pouring an electrolytic fluid into it to replace the worn out electrolytic fluid.
Recharge speed is essentially as fast as refilling the electrolyte.
Still waiting on Serviscope_minor to wake up to fucking reality and realize that Jessica Price isn't going to fuck him.
You think there is anyone left on this site who knows how to do math?
Silly humans
Don't you hate when you just posted your elaborate ramble only to find out how stupid you look not even having read the summary? Damn /. for lacking the edit function (lol)
I don't know ... but it looks like you should be an example of how to solve be problem and simply stop exhaling CO2 into the atmosphere.
If they can turn this idea into a battery (they haven't yet), then that would get them to proof of concept.
If that battery works for more than a few days without a re-fill, that might allow this scheme to work from a practical point of view.
If the electrolyte can be made to not be toxic, then they might avoid environmental issues.
If I had to guess, this is an SBIR shop, and not a legit company (they're going to be selling research papers to grant managers, not batteries to consumers).
In the USA we still get a large portion of our electricity from coal. Certainly natural gas and nuclear fission provides a good part of it too, and they have contributed greatly to our reductions in carbon output lately. The article mentions the potential for recharging the battery fluids with wind, solar, and hydro but wind and solar are much more expensive than coal and hydro is a resource we've already maxed out. Unless the prices of wind and solar can get below that of coal, or we build nuclear power at a rate that can replace the aging nuclear power plant AND aging coal plants, then we will be building more coal power plants to charge these cars.
I have people tell me all the time, "just you wait, wind and solar will be cheaper than coal any day now". That's great! Only what should we do until that time comes? People will also say that the time has already come for wind power. That's great! Then what are we supposed to do if the wind is not blowing? People will tell me that we should charge up batteries for when the wind is not blowing. Great! Except now with wind AND the batteries then wind is not cheaper than coal any more because it relies on doubling or tripling wind capacity and the cost of the batteries. If instead one claims we use a national smart grid instead of the batteries then the cost is in the wires and other infrastructure.
Any plan to reduce carbon output that does not include the use of nuclear power is a fantasy. Waiting for wind and solar to get cheap enough to replace coal is waiting for a ship that may never come to shore. I won't say it is impossible for wind to get cheaper than coal, only that we don't know when or if that will happen. Waiting for that to happen is not a plan to reduce carbon output. Taxing carbon is not going to make that happen any faster, it will only make us all poorer.
I believe electric vehicles hold promise and I wish all of those developing this technology the best. The problem though is that this is just half of the solution. The other half is either nuclear fission or waiting. I say we should not wait.

From the looks of it (colored chemicals in test tubes) this is a vanadium flow battery. They are known for quite some time but suffer from low energy density, so they aren't even used for stationary applications where additional weight (and volume) is less of an issue.
"We will definitely have electric cars that are cheaper to manufacture, cheaper to operate, and cheaper to maintain"
Wishful thinking. We keep thinking we will develop some magical technology in the future to fix today's environmental problems. That's why the actions taken today are so feeble. We may look like the problem is being addressed with all our heart but we really aren't. The Paris treaty in the news lately is a prime example of making it look like we are doing something when in fact that particular treaty does not do a single tangible thing to better than environment. This treaty is about as useful as a UN declaration. It's non-binding, has no monitoring, no enforcement mechanism, or compliance oversight to make sure countries actually honor any of their public declarations. However this particular treaty did provide jobs to the diplomats, consultants, and academic advisors who created the treaty contents.
If you get rid of all the CO2, then plants will die.
Oh and since methane is a significant source of greenhouse gases I assume you want to kill every cow and pig on the planet and outlaw beef and pork.
At least biologically produced methane is carbon neutral and short lived in the atmosphere...
"“We are at a stage in the company’s growth that we are looking for additional financing to build large-scale prototypes and subsequently manufacturing partners,” Cushman said."
In the US it's about (38 liters) 10 gallons per minute, so It would take about 2 minutes (not counting the slowdown period for pre-pays).
But, I think you missed the point.
You would change the electrolyte, not do a rapid electrical charge.
Since you are reusing the electrolyte, you need to take the spent electrolyte solution out, so a "gas station" would have to have at least one holding tank.
The cool part is that you can keep it all contained because the connections need to be sealed and there should be very little loss, as opposed to basically pouring a highly volatile fluid through the air into a container.
You can't take the sky from me
Don't be stupid and lazy. We will definitely have electric cars that are cheaper to manufacture, cheaper to operate, and cheaper to maintain than ICE's in the very near future (this coming decade, guaranteed).
HEY EVERYBODY! LISTEN UP!
Okay, not that I have your attention I have great news to share. It seems that all of our problems are solved.... Well, they'll be solved in ten years. But don't worry. You don't have to do anything in that time. We have it all figured out. Come back here in ten years, with your check books mind you, and we'll be selling planet saving cars for your garage and solar collecting shingles for your roof.
These cars will cost no more than your last car and be just as convenient and luxurious, more likely even more so. These solar collectors will cost no more than shingles and last just as long. The two together means you'll never have to pay another utility bill or visit a filling station. All with the power of the sun.
Thanks everyone for your attention. In the mean time do as you were, there's nothing to worry about.
[/snark]
Is that the message you want to send? Because I assure you that is the message a lot of people are getting right now.
What does your guarantee give me if you cannot provide what you promised? Won't this mean people will be making the problem worse in the mean time?
I have a solution, maybe just part of the solution but it is something we can do right now. We can build more nuclear power plants. Nuclear fission is as clean as wind and solar, as cheap as coal, safer than all the above, and does not require some future technologies to work. If we give the US Navy some money to develop their jet fuel synthesis program then we can produce fuels made from carbon extracted from the air and hydrogen from seawater. I won't guarantee the synthetic fuel technology in ten years because it is possible the Navy wants to keep this for themselves for a while. But the nuclear power we can have right away. We can build a gigawatt scale nuclear reactor in a matter of a couple years. In a couple years later with experienced manpower we can build two in that same time. Then four, then eight. in ten years we could have dozens of nuclear power plants giving us cheap, clean, and safe energy.
We can't stop there though. We'd have to keep going as those nuclear power plants age and need replacement. That's how we keep them safe, by taking them out of service before they become a problem. Don't worry about nuclear waste either. We know how to turn that waste into medical isotopes, portable heat and energy sources for spacecraft, and so on. All that stuff will be used as it decays away to inert elements or get shot off into deep space.

From TFS: "but we are the first to remove membranes which reduces costs and extends battery life"
The battery life of flow batteries is already ahead of all others which is why they are being seen as a potentially better alternative in grid applications.
From TFS: "Membrane fouling can limit the number of recharge cycles and is a known contributor to many battery fires"
As above the recharge cycles of flow batteries are already well above every other type of battery. And fire? Well the fact that flow batteries don't catch fire is one of their key selling points.
Is this just marketing fluff that is using buzzwords to try and get across? The big problem with flow batteries is their energy density at best is currently less than half of an equivalent lithium battery system. This is a far more important problem to fix.
Mind you I do like what they are talking about. One of the big problems with electric cars is the grid connections for fast chargers. It makes the highway rest stop model of petrol stations difficult to convert to electric. All you need is 3 fast chargers in use at once and you're using more power than the currently biggest petrol station in Europe, and many of the highway stops are in the middle of nowhere which don't lend themselves to easy electrical infrastructure upgrades.
Ok, I'll bite - demonstrate this - with peer reviewed evidence please, not just "Because I say so" or "Everybody knows"
I can't comment on the physics, but I can comment on the impact of something like this.
I am searching for my next car and have been looking at various electric or hybrid options. Most of those fail because they only cover 95% of my use cases, and that's due to the charging time. For example, I sometimes drive a distance for meetings that would not let me get there and go back on one charge of the battery. Which means I have to charge the car somewhere. I also drive to other countries in Europe and that's just not something you really can do in those cars.
The Toyota hybrids sort of solve the problem by charging with a petrol engine. But I don't like the way those feel when driving them - and I have had Toyotas as my last four cars, so it's not that I have anything against them.
If I could get a normal, electric family car with an almost instant charging system, I would definitely buy it. Sure, we would need to have the charging stations built first and other issues. But when fully implemented, this is what solves the problem for me.
I really hope they or someone else can pull this off, so I can stop burning stuff when I drive.
It may be carbon neutral, but it's not global warming neutral. Atmospheric carbon in the form of CO2 has much lower warming effect than in the form of CH4. That is the issue.

"The hands that help are better far than lips that pray." - Robert Ingersoll (1833-1899)
It depends. In my home country of Sweden, an electric car will contribute 81g CO2 per km including manufacture, driving electricity and disposal. That equates to tailpipe emissions from 0.3l gadoline per 10 km, which does not include the energy used for extracting, transporting or refining the fuel. And good luck getting your existing car to even match that number.
Just do without one.
Nobody is forcing you to buy a new car. Do or do not, there is no force.
Whoosh
Japan happens to have the most comprehensive porn market in the world.
Japan also happens to have one of the lowest sex crime rates in the world.
I hope you can bring some facts to support the idea that pornography is "terrible for people".
It's technology like this that will eventually make electric vehicles commonplace. Since the batteries are safe enough to be inside a home, maybe they could store electricity generated during the day from solar panels for use at night.
I wish whoever made the video for Purdue Research Park had left out the background music. It's very hard to hear the speech over the music. At least make the volume of the music such that the people speaking can be heard.
It's June 3rd and we only have one super battery story so far this month? What's up with that?
Nah, Trump's too busy getting it on with Rosie O'Donnell to bother with Obama. The feud between them is just a big cover up.
Many have decided the only solution they will accept is wind and solar, even if it means failure to significantly reduce CO2. The US has greater CO2 reduction in the last 6 years than any other country, but everyone likes to point to Germany as the model, despite spending hundreds of billions with essentially no CO2 reduction, and they expect to see an increase each time they take a nuclear unit offline.
Meanwhile, the French Academy of sciences has made it their official position that France cannot achieve meaningful CO2 reductions without their entire nuclear fleet, based a lot on what they have seen in Germany.
The right answer is a mix of technologies that include wind, solar, and nuclear, and even replacing coal with nat gas in the near term. Its the only one that we know for certain will work and doesn't depend on some miraculous breakthrough in storage or other. China gets its, and they are moving faster than anyone because they don't get caught up appeasing the solar-wind or bust crowd.
Power is energy per unit time. And pumping unleaded into your Toyota represents about 15MW of power. If you have an electric car charging setup that charges as quickly as you pump gasoline, you will have approximately the same power transfer.
So what is the connector going to look like? Are you going to want to be anywhere near it while your car is charging?
Which leads to another question. Charging a battery is not one hundred percent efficient. Even with very efficient designs you are probably going to have ten percent power loss. That would represent approximately 1.5MW of waste heat. Enough that you could easily use the passenger compartment of your car as a kiln. Where would that waste heat go? And how do you keep your car from melting?
What was the assumption for electrical source generation in your numbers? Was it today's mix of generation technologies or some future, not yet existing scenario?
Replacing goal with gas is good, but when the gas runs out, will you switch back to coal ?
We have fixed or improved so many of our environmental problems already in just the last half century. It's not magic, it's steady technological progress plus regulation. You might as well be standing here saying unleaded gasoline can never be competitive and the only way to fix the lead problem is to ban all cars. Absurd as well as impossible.

I presume the used electrolyte can somehow be restored to its former usefulness in these batteries. Can that be done at the "charging" station or must it be stored in large tanks and then transported to some nearby industrial plant? Otherwise, it will need to be disposed of as hazardous waste.

There are some extensive systems that recycle huge volumes of liquids such as spent motor oil generated at car dealerships and oil change locations (Jiffy Lube and such) and the spent deep fat frying oil from fast food places and other restaurants. Both of these sources of liquid waste are recycled into useful products.

China gets its, and they are moving faster than anyone because they don't get caught up appeasing the solar-wind or bust crowd.
And just a few posts away, I can find someone complaining about China's growing coal fleet.
Meanwhile, in the US, the few nuclear units under construction are over budget and behind schedule.
So don't blame this solar-wind crowd, find the real problem, not a scapegoat.
I would assume that any gasoline ban would apply only to manufacturers... not owners. It would likely take no more than a generation for electric to be utterly dominant. Used gasoline cars would continue to be available in used car lots, but as more charging infrastructure is continually added to enable the installation of rapid charging pump facilities throughout the country, the demand for gasoline cars would continually drop.
I'm not saying I would advocate such a ban, only illustrating how, I think, such a ban could feasibly work. Kinda like how DVD's and then Blu Ray ultimately all but completely replaced VHS.
File under 'M' for 'Manic ranting'
Crap! I meant to hit "Preview", and I hit "Submit". I know full well that VHS was never banned.... I was using that as a comparison for how, over time, one would replace the other, not because I thought that VHS was ever outlawed.

Tesla 100 kWh battery to be reachrged "instantly" let's say in 1 minute (60 seconds) using 220 V DC infrastructure would require only 30,000 A current. Does anyone imagine electronics and cables capable to control 30,000 A 220 V currents?
Why would we switch back to coal? I did clearly say 'in the near term'. Do you think giving ourselves more time to find other workable and more economic solutions while very quickly reducing our CO2 output for lower cost is a bad thing?
Why would we switch back to coal?
Because it's cheap and available.
Do you think giving ourselves more time to find other workable and more economic solutions while very quickly reducing our CO2 output for lower cost is a bad thing?
Of course not. As long as you don't lose the sense of urgency, which is a real risk.
As long as you don't lose the sense of urgency, which is a real risk.
Urgency is the main reason to replace coal with gas, it is the fastest and lowest cost move to make the biggest dent in CO2 emissions. But unfortunately many don't like that approach.
A relatively small car battery stores around 50 amp-hours of charge.
That means to fully charge it, you would need to input 1 amp of current for 50 hours. Or 50 amps for 1 hour. Or 3000 amps for 1 minute. Or 180000 amps for one second.
The average house wiring is capable of carrying 10 or 15 amps. 3000 amps, much less 180000 amps, is beyond anything imaginable for a local charging setup.
You can pry my gay little miata out of my cold, dead fingers.
A relatively small car battery stores around 50 amp-hours of charge.
At 12V, so the stored energy is only about 0.6 kWh.
The average house wiring is capable of carrying 10 or 15 amps.
At either 120V or 240V, depending on the country, so energy can be delivered at a rate of around 1.8 to 3.6 kW from a standard 15A output. If internal resistance were not an issue, you could draw enough energy to fully recharge that 50 Ah car battery in 10-20 minutes. Or with a dedicated 50A 240V appliance outlet, about 3 minutes.
A Tesla Roadster has a 54 kWh battery capacity (90x as much), so a full recharge would require at least 4.5 hours even with the dedicated 50A 240V outlet. That would be a significant improvement, but still well short of "instantaneous".
Of course in this article "instantaneous" refers not to the time required to recharge the battery, but merely the time to replace the electrolytic fluid. The old electrolytes still need to be recycled or processed to restore their original charge before they can be reused. It would be fairer to compare this process to physically replacing an electric car's batteries with pre-charged spares, which could be done in moments if the car was designed for it.
