Shirley Meng is a professor at the Pritzker School of Molecular Engineering, University of Chicago, and the Chief Scientist at the Argonne Collaborative Center for Energy Storage Sciences (ACCESS). Her research focuses primarily on energy storage materials and systems - including rechargeable batteries for electric vehicles and heavy-duty trucks, power sources for Internet of Things (IOTs), and grid-scale storage for deep renewable energy penetration. She is a member of scientific advisory boards to SES AI, LG Energy Solution, Shell and Ionblox. In addition, Dr. Meng is the principal investigator of Laboratory for Energy Storage and Conversion (LESC), from which startup companies such as South 8 Technologies, UNIGRID and ExPost are spun out. She serves as the Editor-in-Chief of Materials Research Society MRS Energy & Sustainability. She has authored over 300 peer-reviewed journal articles, two book chapters, and holds eight issued patents. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at www.ted.com/tedx
As a mechanical engineering student looking to work with electric vehicles, I found this TED talk very informative. Keep up the great work! I can't wait to join you in your initiative.
Does anybody in the comments have advice for up and coming mechanical engineer student who wants to work with electric vehicles? I'm interning at BMW over the summer, I would love for you to share your story with me and how you got to experience success in your field
Nerd, You could contact Canoo Inc. in Torrance, CA, after you graduate with your BSME. Canoo produces more practical and useful EVs than its competitors. You can research their products online. I am generally not a fan of EVs, but Canoo is an admirable exception.
@@bboucharde Thank you! I'll check them out right now
She is great! Save the world sister!!! Save the the world!
It was an honor to listen to your talk. May the wind always be at your back.
Thank you for your initiative and very inspiring for us
Awesome. We need good batteries that last longer and are not harming the environment (need to be recyclable)!!! Thanks for working on solutions!!! ❤
A lot of people are able to imagine about their dream. In other hand, they felt difficult to make the dream come true. in this video case is the real genius side. "It si not a dream, but it is the reality." I do love the topic and find the new side idea. Thank a lot
Jordan G. had put the link. A very good motivating speech. A buffer for one week. 1% of the GDP. Around 1880-1900 I think in Germany they spent 5% of the GDP in Railway tracks.
Very interesting. The last scheme of electricity use is my dream for long time.
great talk
So Impressive!!!!!
Well actually, the Dutch already build some of these that are being tested...
"Our massive growing love for electric cars....." 😂🤣😵💫
I got like 16 old 18650 rechargeable vape batteries....
I still can't find anything to use them for now that I quit vaping.
A flashlight would be great!
Safer more durable batteries is more important than denser ones, I don't want a battery as safe as li-ion but 4-5 times as dense.
You can store the excess heat energy generated in large sand silos bury them in the ground for extra insulation.
🎉🎉🎉🎉
EVS37 anyone? ❤
We need a better grid though.
Using batteries will make the grid better! It’s already happening in many places like the Tesla mega packs that are being used to alleviate the grid at peak times, you’ll also start to see more home installations happen as prices for batteries come down which they are doing at a very fast pace already. This year alone will see the price of lithium be halved and the emergence of sodium ion batteries will continue that trend even faster especially in energy storage solutions that will create micro grids which will decentralise us from large energy companies 😎👌
😊
Yes queen we do
Please study-Kristen Dirksen and Bryce Langston thanks.
Which of the 3 basic EV drivetrains (all-battery BEV, plug-in hybrid PHEV, hydrogen fuel cell EV) offers the most benefits, applications and potential to reduce fuel/energy consumption, emissions AND insane traffic? Your answer here__ __ __ __
WRONG! The correct answer is plug-in hybrid PHEV.
Which of the 3 drivetrains distributes battery, hydrogen and solar PV array resources most equitably? Again, the correct answer is PHEV.
My sense of the next generation of battery tech is that Lithium-ion will be replaced with Sodium-ion for its similar atomic properties and mining process as Lithium. Its one drawback is its 20% less energy density than Lithium, but - you guessed it - this is not a problem with PHEV packs which are much smaller than BEV packs (Prius PHEV packs are 7.7kwh vs Ionic5 packs which are 77kwh), the difference is minimal.
Which vehicle is most important to convert to PHEV? Answer: Long-haul freight trucks.
The battery resource to power '1' freight truck (5 BEV packs of 550kwh in 10 years) can distribute more equitably to '35' Ionic5 BEV sedans or '350' Prius PHEVs.
The next generation of ICEngine in a PHEV+H drivetrain stores at much lower pressure in smaller-safer tanks and can deliver more than twice the equivalent MPG possible with hydrogen fuel cell.
Just at the end when she said it needed 10T dollars the room became silence. Ok, our government would never make it. Let China did that and we can buy from them.
Already made, they're called hydrogen fuel cells.
sis plz go ahed
Wtf , she wants to sell us batteries???
Sell batteries? No ..the innovation in the grid and structure of energy storage …Our future depends on it
@@TripleB101 AHH, you are a believer in the climate hoax
wishful thinking
Would be great if she'd get to the point and the solution faster. This TED talk could be 10minutes shorter.
Pfft! Give these Ted talks a break. They are on here far too often.
Mentioning needing lots of Li-ion batteries sustainability and cheap electricity in the same extended sentence is just a shining example of this is the age of paradox. 😶
For a start manufacturing lithium ion batteries enlarged quantities is a temporary solution to offset the carbon footprint but by no means sustainable by the current technology we have available, and it carries its own difficulties and problems still from mining to supply chain to manufacturing and to actual installation, lifespan and recycling.
