Dr. Shirley Meng makes the case for hope by demonstrating some of the exciting technologies and new batteries her lab is developing that could close the energy storage gap we need to create a democratization of energy that also enables a fully renewable energy grid.

#Energy, #Batteries, #Innovation, #ArgonneNationalLab, #UniversityofChicago, #Sustainability, #MaterialsScience, #ClimateChange, #Earth, #EnergyGrid, #RenewableEnergy #EnergyStorage Dr. Y. 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


  1. 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.

  2. 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!

  3. "Our massive growing love for electric cars….." 😂🤣😵‍💫

  4. You can store the excess heat energy generated in large sand silos bury them in the ground for extra insulation.

  5. Normalize our local co-ops and Ⓐctive labor unions. Workers make the world run, workers should run the world☭.🔋🪫⚡️

  6. It was an honor to listen to your talk. May the wind always be at your back.

  7. She is great! Save the world sister!!! Save the the world!

  8. Raise taxes on Americans and arrest more Chinese to work for as slaves for free?

  9. 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

  10. 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.

  11. Well actually, the Dutch already build some of these that are being tested…

  12. Electric Cars in the U.S. are a Government scam and everyone knows it now. People charging cars next to a diesel gas generator sums it all up. The US infrastructure electrical grid runs on _______________? 1-2 city blocks of simultaneous charging will crash the grid. Connect the dots do the math, U.S.citizens in a Democratic Republic will NEVER become reliant on EV vehicles, ever. Meanwhile, the Chinese are preparing to flood the US with cheap EV's by building in Mexico as American auto companies report record losses because they did what the Government told them and ramped up EV that no one will buy. Besides, bio-based batteries are coming to market and will blow away lithium but it will not solve the central issue.

  13. Awesome. We need good batteries that last longer and are not harming the environment (need to be recyclable)!!! Thanks for working on solutions!!! ❤

  14. Already made, they're called hydrogen fuel cells.

  15. Please study-Kristen Dirksen and Bryce Langston thanks.

  16. 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

  17. Would be great if she'd get to the point and the solution faster. This TED talk could be 10minutes shorter.

  18. Thank you for your initiative and very inspiring for us

  19. Pfft! Give these Ted talks a break. They are on here far too often.

  20. 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.

  21. 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.

  22. 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.

  23. Very interesting. The last scheme of electricity use is my dream for long time.
