I came here from school. There was a newspaper assignment where we were supposed to read an article about better batteries. We were supposed to find the main ideas. I saw it say something about Don Sadoway having a few TED Talks. I recently watched some TED Talks, so I knew I should come here.

[@bugs181]

Most technology take on average 5 to 10 years to even become public consumer products from development. I feel that the rising energy needs have expedited this process. Only 2.5 years in and they have already released their findings to the public. Pretty good if you ask me. Where this technology will really shine is high energy demands for things like solar, wind, or other renewable energies for homes and big businesses. This technology won't have much use in mobile fields.

[@Bloated_Tony_Danza]

bugs181 Cars didnt, after people saw (and heard) automobiles for the first time, everyone wanted one and it just took off ever scince. Cars back then were dangerous, slow and clumsy. Eventually they even had lead in the fuel and people STILL paid for them.

[@bugs181]

Ilir Kumi Actually, it's not well known that the first automobiles were invented far before they become popularized. The first propelled steam automobile was invented in the 1700's. It's true that cars back then were dangerous, however that still holds true today. Fun Fact: You're far more likely to get into an automobile accident than in any other mode of transportation, including walking through a high crime neighborhood. My point was also not directed to any one technology specifically. That's generally how long it takes for technology to go from the lab to becoming consumer products. Some more, some less.

[@santiagoval9899]

according to Ambri's website, they are testing some batteries in 2015 and, if everything works fine, expect to have a commercial "for all" product by 2016

[@aldoileanumeliber]

I could listen to this man for days. Wonderful way of speaking and presenting the matter.

[@NathansHVAC]

I'm no expert on this, but I would guess some of the complexities are: 1) Molten salt is highly corrosive. The correct stainless alloy needs to be selected and tested for the container. 2) How do you handle thermal expansion/contraction? You can't exactly have air bubbles in there. 3) One of the toughest engineering challenges for any design is low price. You can't throw a bunch of exotic nickle based metals at this problem for the container. 4) How do you re-heat to a molten state? This is why no one thought of it before. At first glimps, the problem looks very hard and expensive to solve. Also, size matters very much. Heat content is a product of volume which is a cubic exponent. Cooling is a product of area, which is a square. The volume needs to be sufficiently large so that the heat loss thru the case is minimal compared to power. This is why the ocean takes millions of years to change temperature compared to a glass of water. You are never going to see liquid metal AA cells. They would cool down in seconds.

[@jimstand]

NathansHVAC Your thoughts show a level of understanding that the man in the street does not have.

[@dranin09]

+NathansHVAC 1) Use layers of ceramic that is naturally non-reactive to corrosive materials, outside layers can be stainless alloy 2) Because the battery runs at 700 degrees the expansion and contraction is limited 3) ceramics and the materials used in the battery are abundant and relatively cheap (at this industry scale, when compared to conventional techniques) 4) the process is reversed

[@yahyakhan9745]

Bottom line: The reduced operating temperature (and hence, cost) simplifies the design and extends the battery’s working life, without compromising its desirable performance characteristics. The antimony produces a high operating voltage, and the system returns about 70 percent of the power that’s put into it. Also, testing has shown that after a decade of daily charging and discharging, the system should retain 85 percent of its initial efficiency. Sadoway tells Nature that a large-scale, molten-metal unit might cost around $500 per kilowatt-hour of electricity produced. “Now we understand that liquid metals bond in ways that we didn’t understand before,” he adds in a news release. The team is looking into other metal combinations that might provide even lower-temperature, lower-cost, and higher-performance systems.

[@mikehillsgrove1612]

No stainless is involved. Ceramics are require for the casings. Expansion is calculated and sufficient room left at the top Heating to temperature requires the input of electricity during the 2 phase charging process.

[@Dr_Xyzt]

How do you feel about using concentrated solar light to make chemical fuel? That's what I'm studying, and it seems like a really practical solution for our farm equipment and trucks.

[@garybrown9719]

Tied up

[@blahdelablah]

Ambri partnered with NEC in September 2019 to start producing their batteries at higher scale. Technologies like this take a long time to come to the market, but I'm seeing this deal as a positive sign that they're still on the right track.

[@fish1968-utf8]

the battery is mainly for industry use due to the high temperature requirement. Its advantage over lithium battery is on number of life cycle health retenation, and larger power.

[@andrewheffel928]

I Googled it, the liquid metal battery company's name is Ambri, and they are still developing their batteries. They had a serious problem with the high temperature battery seals and have had to invent a new chemistry for their batteries. The new chemistry is less expensive than the old one, and they project the cost of a commercial battery facility using their process will cost five times less than a lithium ion battery facility of the same size. They hope to have a working unit in 2020. They are still alive.

[@bitelogger]

This guy fire me like a star, has passion, determination, knowledge man we need More people like him to improve the world!!!

[@duncanwallace7760]

What a great approach to one of the major issues the world faces today. It certainly sounds like a battery like no other. Presumably these batteries would be industrial rather than the sort you might have in your home, given the high temperatures needed, but maybe they could be part of new home designs somehow. Look forward to hearing how they develop!

[@vincentrobinette1507]

You're right. These are specifically targeting grid scale electrical energy storage. They may not be practical for home rooftop solar, and definitely not for electric vehicles. think of this in the same category as redox flow batteries.

[@michaeledwards2251]

Articulated lorries and heavy vehicles are potential candidates: they would withstand the very high cycling rates needed.

[@ik04]

This is how all TED talks should be! Chalkboards and hard science rather than fruity ideas and bogus emotional pleas... Verbally documenting an actual scientific experiment is much more entertaining than listening to mere words. Adding a great speaker is icing on the cake!

[@VIIflegias]

12:29 ok, let's see: 16 inches, meaning 4 dm. volume of device: 2^2*3.14= 12 dm^2. the height seem to be slightly more than half the radius, like 1.2-1.3 dm, so volume=15 dm^3 more or less, or 15L. meaning that the Volumetric energy density is 1000Wh / 15L = 67 Wh/L. for a lithium-ion battery it would be 250 to 620 Wh/L so best case scenario it's 4 times less energy packed (per unit volume). not the greatest but if it's scalable and versatile enough it doesn't really matter. we have twice as much anthimony as we have lithium, so that's something. i'd like to know how reversible it is though, and how difficult it is to keep the phases separated, not to mention charge loss at rest (self discharge), i can't imagine this construct being too good at actually storing energy for long periods of time.

[@musaran2]

Energy density does not matter much for stationary batteries. Price is where it's at.

[@vincentrobinette1507]

The question is how many kWh per Kg can this store, compared to lithium? This might need many more times the antimony to store a unit of energy than lithium. I don't have the numbers. but that doesn't matter. As much energy storage as we need as a nation, NO technology is off the table. Think terawatt hours. I don't think there's enough of any resource, for any one technology to meet the demand by itself. We need everything we can get our hands on!

[@hetaeramancer]

[@rob87raine]

This talk is full of optimism and promise, the kind of thing you need to keep attracting research funding. Of course you try to use cheap materials, that's nothing new that's just how to maximize profits! Prof Sadoway makes it sound like it's problem solved here and that they have found the perfect battery chemistry but magnesium-antimony isn't cheap. Actually, a year later they publish a research paper saying that further research is needed both to overcome "enormous challenges" in this becoming economic, and also to explore "rich , new battery chemistries". Don't get me wrong, I wish him the best of luck but there is a race on for energy storage technologies, and it seems that thermal energy storage has many advantages over batteries: for example, allowing offices to run electric chillers at night to produce ice and move their electricity demand for cooling away from peak times. There are also power generators that can switch the balance between heat and power production at short notice without compromising efficiency in order to help balance intermittency through storing hot water in heat networks in countries that have them like Denmark.

[@vincentrobinette1507]

Magnesium seems pretty readily available, but what about Antimony? In deep cycle lead acid batteries, antimony is used as an alloy in the grids of the plates. Only about 5%. that amounts to about 2% of the overall materials in a finished lead acid battery. This battery uses 100 percent antimony as one of its electrodes. That's a lot!

[@ThePintoAce]

"The electricity powering the lights in this theater was generated moments ago." Electricity is a type of energy and most of the electricity is generated by burning fossil fuels. They release chemical energy and in power plants we first transform it to mechanical, then with generators to electricity. Most of the power plants don't store energy. They send along transmission lines as it is generated, but is not stored. That's why he is right.

You are correct, sir. Entropy is the killer. It is inevitable, but can be delayed. Conceptually and principally, the problem we have is more of a consumption problem.

6:26 I like your concept of liquid salt, however I would use a thorium molten salt reactor to produce electricity. Only because that, there would be byproducts, that would be more valuable. Molybdenum 99 for cancer therapies and cancer research, xenon for interstellar space travel, excess heat for water desalinization, etc. your plan produces none of these byproducts. Build a model, too many moving parts, in concept to production. The field application is brilliant. However, for mass consumption, mass generation is workable. In my model you just have thorium reactors on a grid, the grid sends power to where it is necessary. In your model mining, manufacturing, and distribution of your batteries is too many moving parts. Military and government applications, need your battery.

+Will Parsons Will, there was a time when I used to share your enthusiasm for so called renewable energy, the problem with wind and solar etc is different depending who you are talking to, some argue against the economics, others against the clean label given to them, both of these arguments are quite valid I think, but for me it boils down to NET ENERGY. That is, the energy "profit" of the technology after a thorough accounting for all the energy inputs to deploy and maintain it for it's complete life cycle. Net energy is a concept that should be front and centre in any discussion of energy production but sadly it is usually not considered at all. In the case of wind and solar, net energy is way too low to run a techno-industrial-consumer culture like the one we have running right now.

[@dranin09]

+brett rasmussen It is not considered because Net-energy does not account for the limitations (abundance, effect on the environment) of the resource that is consumed. If we wanted the highest 'net-energy' we would still be digging up local coal for coalplants.

[@merc340sr]

[@twelvewingproductions7508]

Great closing line. Unfortunately these batteries didn't pan out. My guess is that there are too many differences between the way these batteries work and the way more standard solutions work. The biggest hole that I found in this is the idea that these batteries would be used for short term. Basically as a capacitor, it is used only for brief periods when it is not being charged. The problem there is that a battery in it's penultimate form would take a charge and be able to keep that charge for weeks or even years. This battery can't continue to operate long without input. How long I don't know.. but something has to keep it hot. My guess is that "something" is electricity. There is no free lunch here. Molten salt "batteries" are already in use in a more pure form.. solar to to heat. My guess is that doing it that way is many orders of magnitude more efficient for short term storage than the idea he presented. When I was first seeing this video, I thought he was talking about a flow battery. In a flow battery, electricity is used to plate zinc. When called for, the Zinc is allowed to lift off the plate back into solution.. creating electricity. Elegant, fairly simple. The problem with flow batteries is the mass. You don't get a whole lot of current per plate, so you need a lot of them to provide useful power. But it IS possible. Anyway, I did enjoy the final quote. That part is true and worthy no matter if the idea panned out or not. Sometimes we do things because it's worth while to try them.

This video has NOTHING to do with real engineering.

[@jimstand]

I have been following this video for more than 5 years now. It is a total of 8 years since this Ted talk. Where are the batteries? A press release and a fancy website does not count.

[@albertjackson9236]

This man appears to me to be more hype than true science & engineering.

[@joemc111]

Albert Jackson just another guy that ant got crap.

[@beenn15]

AMBRI

[@Carnutzjoe]

There needs to be a KZbin setting to screen outdated videos.

[@gabel13]

this guy wears his watch over his shirt, can't trust him

[@johnh7101]

+Gabe Barouh How insightful of you. I agree with you, that's freaky and a little scary too.

[@StefanReich]

lol

[@Channel4Nature]

He want to save time

[@WadcaWymiaru]

What he talk suit him, not the clothes...

[@qaz9258]

An inventor thinks out side the box, the box that is completely imaginary. the boxy that says no^3. That one has to have his watch under his shirt is an imagined wall. It makes so much more sense to put the bulky and informative item over the thin constraining item.Thus another proof his thinking is not bound by others imagined limits. So you are are left in the dust with your lack of trust we are gaining trust to break this crust.

i am curiuos what the loss of energy is between the Mg & Sb and MgSb and back to Mg & Sb. Also i am curiuos if they have a way to radate off execive heat in high demand or charge cycles(easy fix if they look at old soviet sub reactor designs, which will produce more energy)...i have tons of otehr questions also, but an hopeful this can work.

[@scottbros6368]

March 2012 preaching a new battery?? February 2019...where is this magical battery???????

[@bartoszbarejko1585]

This liqiude metal is not good Technology. I am starting soon with 90 % H2O2 Batteries in Graphene.

[@bradhaaf4749]

Found it, though different chemistry. www.forbes.com/sites/natalieparletta/2019/04/03/new-thermal-battery-could-be-a-game-changer-for-storing-renewable-energy/#48ab080d4f95

[@jakedevents]

That is what I was thinking too, for at those high temperatures what kind of crucible could withstand the corrosive forces for a prolonged period of time?

[@MrGerdbrecht]

Do you ask about corrosive forces in nuclear plants too?

[@EddieVBlueIsland]

Now its 8 years where' s my flying car?

[@HKspurs10]

is this the same as vanadium redox flow battery?

[@aniksamiurrahman6365]

Wow! Professor Sadoway is a great motivational speaker! I bet he makes his students work to death(with passion) LOL!

[@46monkeyes]

Anik Samiur Rahman Were you one of his students at MIT?

[@HaydenLam1337]

I want to know price, and whether it can be implemented at a household level...

[@chapter4travels]

A giant battery would make wind and solar outrageously expensive.

[@nukeelda]

I'm asking professor:Did you use natural balance in Weight between 2 chemical's, I would waight them in pythagoras way or golden ratio...

[@brewmaster95060]

the word average is dangerous PEAK usage is what I what to know

[@dranin09]

+brewmaster95060 You can lower peak-usage because of batteries, 'averaging' out the usage. It's not dangerous it's math.

[@jimstand]

@@dranin09 And you don't understand the application of math to this problem.

[@Williraser]

what if there is no current going through the batterie, is it going to cool down and become solid because i think that would be a problem. good idea but not gonna happen if you could loose all your batteries just by 1 shortcut

[@Arnond35]

Did he just add another step towards T-1000?

[@dezertmiragez]

This is why I subscribe to TED. Videos like this

[@jimstand]

And no batteries to show for it.

[@sportbikeguy9875]

"were not going to conserve, drill or bomb our way out, we are going to do it the old fashioned American way" LOL how ironic....

[@blaked7532]

Is that Hagoromo your using on the blackboard?

[@wesleycooper7159]

I thought batteries came from Iraq in the middle east? The Bagdad batteries.

[@MithranArkanere]

Are they making SAI backup batteries like that? Last time I checked they way horribly expensive.

[@robertebersold3817]

I wonder if Elon Musk watched this video....

[@AtlasFullsun]

How do you keep the metal and salt liquid?

[@jimstand]

With heat.

[@Ctajm]

7 years ago now. No batteries.

[@Wurtle38]

sorry if this is a stupid question, but how do you maintain, I'm guessing 1200 F all the time?

[@TheJamescomiskey]

THE GOOD OLD AMERICAN WAY GET PEOPLE FROM OTHER COUNTIES TO INVENT SOLUTIONS AND THEN BUY THEM!

[@kussh100]

whats the cost of these giant batteries, if any were made? its almost end of 2019 now

[@popifar]

they had to invent their bombs first

[@xapemanx]

what is the efficiency of the battery?

[@cancoteli9669]

Thumbs up for 3.091 !!

[@bestnocture]

bothumbs up

[@brendan0077]

Why does 720p load faster than 360p?

[@cedriceveleigh]

There's quite a few useless ted talks now days, but this one's definitely not one of them!

[@jimstand]

You are falling for a com man. You don't understand the science.

[@archaedemos]

Just watched you on Colbert!! and also watched some MIT vids in the past ,Big fan!, You are a very smart man! great upload!
