- Jeff Dahn has won countless award for his work on batteries. His talk highlights some of his research experience.
Dahn has received National and International awards including: International Battery Materials Association (IBA) Research Award (1995); Herz- berg Medal, Canadian Association of Physicists (awarded to a physicist under 40 years old for career achievement - 1996); Battery Division Research Award (The Electrochemical Society - 1996); Fellow of the Royal Society of Canada (2001); The Electrochemical Award [Canadian Section of the Electrochemical Society - awarded once every 4 years for career achievement] (2006); Medal for Excellence in Teaching (2009) from the Canadian Assoc. of Physicists and the “Technology Award” from the ECS Battery Division in 2011.
This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at ted.com/tedx
Jeff Dahn is a very smart, humble, and realistic person. He is describing the achievements of his department and university in respect to this new research partnership with Tesla. He also provides truth into the renewable energy hurdles that need to be overcome in order for it to be at the same cost as burning coal for energy. He's not proclaiming that Tesla will change the world, he is saying that we should all be very greatfull that Tesla has drive and passion to lead that charge and explore that future.
Two years down the track and Jeff Dahn has made significant progress in Li Ion cell longevity with electrolyte composition and additives - well done. And Tesla will be the main beneficiaries.
Professor Dahn has dedicated his life's work to battery technology. His calm and humble demeanor gives me great hope and comfort for the future.
Jeff Dahn has an amazing ability to break down super scientific topics into digestible and interesting topics. See his other lectures, this one is targeting a more straight forward audience but he definitely knows his stuff.
5:08 I gotta be a part of this. 6:37 Fortune magazine: Dahn Tesla's new weapon. (;-) 7:09 Tesla Powerwall. 8:33 the value, importance of accelerated testing to simulate years of battery life. 10:18 the importance of grid-scale energy storage for climate change mitigation. As storage doubles the cost, bringing down battery cost is key.
Amazing work Sir Jeff
He summed up his acheivement at the beginning of his talk and NO ONE clapped their hands showing apprrciations. Wow.
I love this!!!
Bravo!
Can I use portions of this in a RUclips video I'm creating?
And now he's helped Tesla develop the million mile battery.
Capture from solar is what wave length range?
While it may not seem much. This man is talking about a major technology which will rule the future. Strange that tesla has only one collaboration though.
Panasonic are the battery making partner at the gigafactory... so they will provide most of the research in to battery technology used there.
Shared vision/ passion, extraordinaire.
This is from early 2016
my prof
Felt more like a Tesla commercial, with a title like "Making batteries better..." I would expect a discussion about future battery technologies.
Yep, he also does not mention that Li-Ion batteries have a horrible carbon footprint when produced... So they will pretty surely not be the future of batteries!
Ha Ha you felt the same way....hahahaha
Tidal lagoons can deliver continuous electricity the lagoons are constantly emptying and filling. The times of the tides are known for decades in advance. The lagoons can provide bridges, flood defences and fish farming as well.
Massive infrastructure costs. Opposition to wilderness land use. Would require depopulating the world for this to likely have much of an impact. But if you can finance projects without subsidies, go for it!
It's a pity that I didn't know they are sensitive to heat would have saved me buying new ones for my drone, I did enjoy the lecture.
Jeff you are my God.....
nice pep talk...
The Gigafactory's new goal is 150GWh/year of production and I'm willing to bet it will be closer to 200GWh by the time it's finished.
Sorry, pal, but that's only a goal.
It's 2019 now and Tesla is still at 23 GHh/year.
What you are telling is a *long-term* goal.
Awsome.. This guy is a genious!.. WOW... him to have Jioned TESLA is simply the best that could have ever hapenned about battery !
1) This was a fucking Tesla commercial. 2) Lithium Ion batteries are never going to be the answer. 3) Electrification of light passenger vehicles will do almost nothing for CO2 4) Tesla couldn't exist without gov cheese. Elon Musk is no visionary.
1) This was not a Tesla commercial. 2) Lithium Ion batteries are in fact the answer. 3) Electrification of light passenger vehicles will do a lot for CO2. 4) Tesla doesn't need any gov cheese. Elon Musk is the definition of a visionary.
+tarstarkusz
Bravo!
+Al Rats Even assuming li-ion batteries were a good replacement for gasoline, what makes you think this would do a lot of reducing CO2 emissions? Do a little more research on Musk and Tesla, it's government cheese after Paypal. Paypal, when Musk was running it was stealing a lot of money. You either forget or weren't around when Musk was running Paypal and all of the paypal complaint page were around.
Internal combustion engines in a vehicle have an average energy efficiency of about 18% to 20%. Electric motors are about 85% to 90% energy efficient and lithium-ion batteries deliver around 90% of their electrical input to the motors in an electric vehicle. Large stationary power plant turbines are typically significantly more efficient and cleaner than small mobile combustion engines in vehicles. Electricity transmission losses are around 9% on average.
In any case, the electricity that is used to refine all the petroleum liquids that are used for road transportation today would by itself be enough to power electric-vehicle counterparts to all the vehicles on the road. It takes several kilowatt-hours of electricity to refine each gallon of petroleum fuel. The fuels then need to be transported in ships, trains or trucks.
In countries such as Canada, France, Iceland, Scotland, Norway, Sweden, Austria, Switzerland, Brazil, Paraguay, New Zealand and many others, almost all the electricity comes from Nuclear or renewable sources. So there will be very substantial reduction in pollution and carbon emissions in these places. Proportion of renewables in the grid in most countries (eg. China, India, EU) will increase dramatically over the next decade.
The manufacture of lithium-ion batteries and electric vehicles currently requires more resources and energy and mobilise more toxic substances than manufacturing comparable vehicles run by internal combustion. However, the impact of this is more than offset by the significant reduction in air pollution and CO2 emissions produced during the use of the vehicle. And almost everything can be recycled at the end of the life of the vehicle. Electric vehicles can also be expected to last longer with less maintenance since there are few moving parts involved.

We have free energy In many ways Its being held back
Yes, by nature itself, though, unfortunately.
Fred
Nice talk, but that's bare metal before the Gigafactory had a roof on it, no solar panels on the roof yet.
hahaha yuppers hahaha
Eleven months later - they have a smidgen of solar panels on the roof as of end of February.
With the new Solid Electrolytes I think an Lithium or Sodium Cell will last much longer.. I think it is the Key,
if it work in Fact, like the Scientist say.
svesom Sodium isn’t an option at the moment. It’s gonna really take a long time to end up being practical
Still waiting for sodium. LOL
@@ricklearned1686 For now now Therese are other Options.
See the Advantage of Teslas Million Mile Battery.
I can wait until the newly rescheduled Battery Day in September. I have more confidence in Musk and his team of people like Dahn than Sodium.
@@ricklearned1686 For now it seems to be the best Battery Improvement we can see.
Isn't the Nissan leaf was the first electric vehicle ever (mass) produced to show that electric vehicles could be functional and green and yet amazingly cool and awesome?
Amazingly cool is a far stretch
Nope. Mitsubishi i-miev was the first mass market electric car. But not cool and awesome... ;-)
The issue was they made an ineffective battery management system that did not properly consider the longevity of the battery. It's why Tesla jumped past them so quickly.
my friend, your hemp supercapacitor with ionic liquid castor oil is just the answer, oil will be gone.
The title should be: Jeff is honoured to work with Tesla and Elon is an awesome man.
I think this guy can ameliorate the power of my EDPZ i explain you it is just electron accelator in a cristal maille with polymere ionic in heart the speed of the electron make them live the orbit with a laser light as connector....
Oh you think of russian dolly....
How's about a little less Jeff & Tesla and more about making batteries better?
When demand for gas drops, so too will it's price. Conversely as demand for electricity increases, power prices will rise. 2 things for certain - we're going to need a lot more nuclear power plants and fossil fuel vehicles will still be around in 50 years.
The connection between gas demand and price is weak, though that is the general tendency. The price is way higher than production costs in Saudi Arabia, UAE, etc, but it is likely that these societies would collapse if oil profits disappeared. For power prices, it seems that they are driven by how aggressively countries pursue fossil fuel replacement, rather than say per capita demand. If producers are allowed to use low cost hydrocarbons, especially coal, they can meet significantly greater demand without significant price increases. But on the other hand if countries shutdown currently existing nuclear and coal plants then prices will rise significantly. If storage costs drop significantly (say by organic or other non-lithium based redox flow batteries, or continued progression on a learning curve for Li-ion), then photovoltaics might have significant market penetration. Continued penetration of wind power will raise costs by driving massive investments in transmission capabilities.
I was hoping to learn something new about batteries in this talk. Got nothing.
me too - oh well . . . the technology is pretty advanced and advances in battery design and materials come slowly but surely over time.
Yup andrew...once you accept Tesla, you must sign a non-disclosure agreement so any great tech gets swallowed up by them and buried...nothing new here...the only cells to buy are lifepo4 for all your uses
Search his name on RUclips. He has some tech talks out there too. Very educational.
Andrew Lohbihler
I agree
Thought I was crazy. Half the video is gloating.
power grid probably wont be cut with lithium ion batteries, my bet's on sodium ions battery for power grid.
needs a 10x speed
Tesla is doing a great job and he is changing the world. I wish he would put all the money he is spending on solar and battery storage into molten salt Nuclear reactors. If we really want to go emissions free I really believe that the way to go is Thorium molten salt reactors. The fact is solar tech now just takes up too much space and wind mills are too unreliable in many parts of the world. Thanks
They have figured out methods to speed up battery life testing instead of waiting the 20 years. That's significant! It's like what car and air craft manufacturers do, they set up a machine to push the parts back and forth for weeks or months to test them. They must have some good and probably "secret" technolgoy to do this. That's why he didn't say anything about the technology. I think Elon is fighting the corporate side with shareholder concerns. It's kind of like Jobs who wanted to push further but the masses were not with him when the Apple took him off the board. Not a problem for Elon. He's truly got a lot of followers. But the corporate giant will be pushing back. I believe most of us have it in us to do amazing things too. Some people choose to. A little good luck doesn't hurt.

Lithium Ion doesn't make a lot of sense for grid-scale storage. Pumped hydro is much more realistic.
It depends on where you are. There are some places that gets plenty of sun/wind but not a whole lot of water to pump.
Pumped hydro has been around a long time, so the most profitable sites have already been used. It has long payback times, and faces serious wilderness land use opposition. It seems like redox flow batteries based on newer chemistries are more promising than pumped hydro. But that requires some impressive breakthroughs in membrane costs and suppressing side reactions to obtain long lives.
There are many storage possibilities and each has their pros and cons.
Flywheel, pressure tanks, hydro, batteries, power-to-gas, etc., but the market is still to small to get proper R&D and create an industry of scale.
I personally find hydrogen (or artificial natural gas aka power-to-gas) the most interesting. (If there is to much electricity in the grid you create hydrogen(natural-gas), which you can distribute with the current pipelines. And if you need heat, you can either use electricity if it is cheap and when it is expensive then you use the stored gas. There is a lot of potential.)
Batteries have the upside that right now a lot of R&D is done and due to cars the market will explode. (VW for example plans to invest over 40 billion in R&D in the next couple of years and plans to sell at least 40% of their cars as electric till 2030)
is he trying to sell tesla products through TEDx talk?
Instead of that sign language female - why not put a CC button on this video?
So annoying but for the one percent of the one percent
12 GPM shower - because his goal is virtue signalling on behalf of a giant corporation kept alive by tax dollars and false promises.
This doesn't show how they will make batteries better. I wounder why. maybe because no one has figured out how to make a battery last 40 years
Change the title of the video to be “making more* batteries with older battery technology”
Forget Tesla. He was an AC guy. Tell us about the batteries.
I read an article the other day that labelled Elon Musk the 'founder' of Tesla, lmao. It was invented and founded by two guys in their garage 15-20 yrs ago. They held on as long as they could but eventually just could not capitalize enough to keep building so had to sell out. The Tesla is still the same basic concept - small roadster with the entire fuselage packed with 18650 Li-Ions bunched in modules, which are now, today, November 2018, Li-Ions just got hit by an E.L.E. akin to the dinosaurs. CARBON BATTERIES will extinguish them.
You don't need to test it for ten years. You only have to charge and discharge it and seen the difference over a peroid of a yr and use some math
Only if you can accurately predict the form of the degradation. Typically, you make mathematical models on the sensitivity of aging to various factors, then use accelerated aging techniques. For example, Li-ion is sensitive to charge/discharge cycles, so you can get a good indication of expected life by going through multiple cycles in a day.
No panels on that roof yet. surprised he doesn't know that.
panels on the roof will provide a small fraction of the power consumed by the gigafactory... if Musk is dedicated to the renewable cause he would also build a large solar generation and battery storage facility next door to make it self sufficient.
David Costello - If the roof will only provide a small fraction of the power consumption, then you wouldn't need batteries at first. The roof was designed for panels, so it should be the cheapest location for building out solar farm. At the end of February, the first block of panels has finally been installed. My guess is that there is not a strong cash flow case for installing PV panels. So it will proceed slowly, to either wait out the anti-dumping tariffs or take advantage of further price declines.
Musk also owns Solar City and is marketing a battery storage solution for solar generated power.... which is great for the home market and yes batteries can be used on solar farms too.... but installing batteries on the gigafactory roof is a marketing gimmick... and this video isnt much more than an advertisement
I think he is marketing, rather then selling it. The price is so low compared to competitors, I figure it is a technique to get cash from deposits, dole out a few units here and there, and hope the majority of folks eventually give up and ask for there money back. The very best type of loss leader, one that gets you publicity and deposits, but that you never actually deliver on. My analysis is based on speculation that his actual cost for batteries is way higher then his claimed cost. My guess is that battery manufacturers are participating in the scam by occasionally selling batteries on the open market below cost to convince the analysts that Li-ion costs are actually significantly lower than that they are. Hoping that they can forestall the crash in interest if data showed that the learning curve model wasn't fitting anymore.
"Earlier this month, Tesla reported it produced 260 of its new Model 3 electric cars in the third quarter, of which it delivered 220, dramatically missing CEO Elon Musk’s prediction that the company would produce more than 1,600 cars by September."
Maybe he should watch Planet of the humans....... LMAO
Brilliant guy, giving a totally useless talk. It's one big commercial for Tesla and nothing else.
Exactly my thoughts got a little information for 13 mins talk.
Bill gates ranked as one of the most visionary people ???? hmmm no..... He got windows from Steve Jobs. His company wouldn't exist if it wasn't for Apple.
Who built this red and white TEDxDalhousieU sign? It's awfully made!
this guy is a joke.
useless ad talk!
Interesting presentation, I've always been amazed how battery technology has all but stagnated in comparison to so many other technologies (CPUs, storage, medicine, etc.) I can only imagine, today, of a smartphone that is slimmer but more important, is able to run on a single charge for a month, or even years. Nice. And cars that can run 10,000 miles or 20,000 miles on a single charge and costs 1/2 less or 1/4 of the cost today. Someday we'll see that, no doubt, but it's anyone's guess when. Tesla is making good advances so I raise my proverbial glass to them for their burgeoning efforts. (But WHY oh why did he have to throw "Global Warming" into the mix? Yeah, the Earth gets warmer (and colder) all the time. That's hardly news. I'd fairly sure he's talking about MAN MADE global warming but sorry, I'm not a believer. Never was because it seemed obvious to me there existed no valid data to support it. I don't want to start a debate, I just think his speech time could have been better put to use on BATTERIES, the topic of the presentation.)
Again though, while we do have a long way to go, I'm certain our understanding of battery technology will improve dramatically in the coming years. Maybe not quite as fast as "Moore's Law" (Which, of course was never a "law," it was just one man's observation,) but science tends to improve dramatically, very quickly. Especially when true breakthroughs are discovered. I'd like to add more, but my laptop's battery is almost dead ...
I want my 13 minutes 39 seconds back. That was pretty much pointless.
China is already moving away from old lithium battery technology ..China is developing a new type of battery without the use of Electrolytes...easy to charge and long lasting ...
source?
This a sales pitch! Unfortunately for tesla! "HE" Elion Musk is doing great things, But! There is technology out there on batteries that have lasted for over 40 years.... First I hate to even mention the name but this battery last over 40 years, "but " its to heavy for cars. Great for homes, sucks for transportation ! TO HEAVY! It is the Edison battery its been around more than 40 years and can be refurbished and very safe! It has nickel and iron in it! So yes on home no for cars! Graphene batteries are best for cars , but no one has been able to mass produce graphene ! Or at least it just hasn't been exsposed to the public YET!
Where have you been? The Edison battery is a chinese scam.
Elaborate? What type of scam? There are people that are using this type of battery today here in the U.S.?!?!
I’m sorry, I guess that was silly to make a comment without explanation.
There is nothing wrong with the Nickel-Iron NiFe batteries themselves. And,
they certainly can take a lot of deep cycles.
The problem is: a Chinese company is using the name Edison Battery, and
those are very cheaply made and are junk.
They are also very expensive for the Ah they provide. Fake Chinese batteries are really hurting the battery industry, if we could find alternatives that would be cool. Exide used to make them here in the US many years ago I believe.
Well, one major issue with the Edison battery (other than the weight, the low energy density, the super slow charge rate...etc) is the rather large self-discharge rate. It's like hauling water with a leaky bucket, no matter how environmentally friendly you build that bucket, if it's very leaky your efficiency in hauling water is going to be pretty bad. The chemistry itself is pretty good, we just need a modern way to improve upon it and make it competitive with some newly emerging batteries. One such is the aluminum-ion battery that can cycle just like an Edison battery yet carry more capacity while being built out of lighter and cheaper materials. I see a lot of promise in utility-scale storage in this technology.
Just FYI, friend...LiFePo4 is the future, if you want it...
"Canada Cool" as carbon-quack narcissism.
1st
Lots of bragging about himself and his team, but didn't teach anything innovative or of quality as the title of his talk claims.
13 minutes talk, but talks nothing.
Horrible talk, went nowhere
yawn...
I am laughting on the past scientist nanodiamond is a lie cause the carbone is bipolar.....
It is mean that you cannot made a maille with less than four atomes a line or the size of the carbone is close to nano....
hence why America had to steal Afghanistan mountain of lithium
No lithium is coming out of Afghanistan and there are huge deposits of it in much friendlier countries. Lithium is cheap and abundant and only makes up a very small percentage of a lithium ion battery. US involvement in Afghanistan has nothing to do with lithium.
A Tesla Model S at around 2 tonnes is not a "green" car by any stretch of the imagination. I'm a huge Elon Musk/Tesla fan but I don't kid myself.
First walk more, then cycle, then public transport and finally the smallest most efficient car you can find.
