Professor Shirley Meng: The Future of the Anode (C, Si, Li)
ฝัง
- เผยแพร่เมื่อ 14 พ.ค. 2024
- Today I speak with Professor Shirley Meng about the future of the anode. Including Carbon, Silicon, and Pure Lithium Metal (C, Si, Li). Shirley has specialised in nanomaterials engineering and I think she’s the perfect person to speak with about the recent excitement around silicon anodes (nanotubes, nanowires). Today, the focus will be silicon, but we’ll also go a bit broader and talk about what we can generally expect from battery anodes in the next few years.

Wow you got Shirley Meng. I’ve heard her name so often and never heard seen or heard her this is a treat for me. Thank you
Shirley Meng has several great TH-cam videos about batteries, well worth watching!
Sunny Chu Thank you I had no idea cheers
39:25 Shirley Meng: My goal in life: EV exceeding range of ICE vehicles, with 400Wh/kg.
Ding ding ding! Thank you Shirley 🙏 You’ve got this ✊
Shirley Meng - a hero working to save the planet with energy storage! More power to you Shirley!
Two weeks before Battery Day ... and you score an extremely rare interview with Shirley Meng! You sir, truly, are a friggin' Rock Star!!!
hehehe
I was thinking more like James Taylor than Robert Plant....?
😁
@@rogerstarkey5390 LOL ... hey, who said "up on the roof" doesn't make you a rock star?
Shirley made everything she said crystal clear. She is a very good speaker. Thank you for interviewing her. Lots to be exited about.
What a wonderful interview. I enjoy the passion she has for the future.
We must not let her defect to the CCP
@@charlech Duh She would only be going home
Superb guest professor. Almost all female engineers in America are foreign born. America culture just kills the science bug in our native born females, ..... just shameful.
raniera stevens: That’s what I thought as soon as I saw that “defection” comment. As with almost all female engineers in America, she is foreign born. In America, our native born women DO NOT PERFORM in science. How shameful!

It's amazing how quickly you have gone from a tiny upstart channel to the go to place for everything batteries! Great job!
Shirley Meng is a treasure and an inspiration...!!!
I like her mix of professionalism, enthusiasm, and friendly demeanor.
She speaks with such passion, I'm impressed, her eye light up like Elon's
That was a great interview with a real battery expert. Very exciting.
Oooh shiiiii you got Shirley! Well this is now the best channel on TH-cam right now.
SCOOP!!
(Demonstrates your growing reputation!)
hehehehe 😁
Loved this so much! Thanks for this interview both of you. It opened my eyes a lot!
So amazing that a world class scientist, like Shirley Meng, is also such a pleasant person.
Your viewers and her students are very lucky!
Top interview, how do you get these guys, they are the knowledge holders. Well done.
Simple.
Understated respect.
LOTS of research.
An exceptional (Imo) ability to understand and describe the concepts in "words of one syllable" (or as near as possible).
Jordan, you may 🤭, but it's what I see.
This is a great channel. The only channel I subscribe to, and the one I understand the least.
I especially enjoyed the end. Very inspiring. And as well as being very knowledgeable, Dr. Meng is very cool. A great interview. Thanks!
Thanks Paul, I appreciate the support. Yeah, she was cool 😀. Very easy to talk to and full of ideas.
More to the point, a"tiny upstart" who "knew nothing about batteries" to way beyond the average comprehension (and I suspect beyond many high level students)
That's such a great combination of super-smart lady and positive thinking about her role in the grand scheme. I hope Shirley gets great students and together they can accomplish their goals. Thank you for conducting the interview, and for the thought-provoking content Jordan.
Shirly..... I don't know if you will read this but thank you for making the brilliant choices you've made... The efforts of you and your colleagues are very ,much appreciated!!
What a pleasure listening to Professor Meng and her Optimistic hope for the future. I’m in her corner!
I can't even express how delighted I am to see Jordan getting guests like this. The caliber of research he's done warrants it, but that's not always enough to get experts like this to share their insight with this series of tubes, or truck if you will, of the interwebs.
😀 I've been biting my tongue for the last 10 days, lol. REALLY wanted to tell everyone.
Shirley Meng is a full of enthusiasm, and hearing her speak about an optimistic future whilst showing restraint (cautious against over promising), makes me excited for the hope of our planet
The best takeaway: ‘if you are an optimistic person: we have 30 years of time. If you are a pessimistic person: we have 20 years of time’
There’s a huge portion of us watching this video that will be alive during the point-of-no-return tipping point. Amazing and frightening at the same time
Love Shirley’s enthusiasm for grid storage. When you think about it at the base level, the sun bombards earth in humongous levels and so much gets radiated away into space that if we could store just a few percent more we would all be richer. Until now most of that storage has been in crops and food, we now have a path to so much more potential.
Maybe if we can store enough energy on the sunny side and store it then use it on the dark side, we might even be able to influence global warming a tiny bit!
First thoughts.
(Started taking notes at 20:00)
1) WOW!
2) 21:20.... $65!! (Even beat *my* "optimistic" prediction!)
3) 25:40.... Lithium Sulphur 2021 (lab? Production testing?)
4) 37:00 ... Batt/ Cap hybrid (larger vehicles)..... Skeleton interview???
5) 38:09 .... Confirmed targets 400/500 Wh/kg
6) 39:15.... High Lithium cathode = 400Wh/kg
7) 41:00 .... *Get a message to Elon! Shirley on battery day* !!
8) 42:15... *Nice Compliment* !
Don't let it go to your head!! 😁
......
Don't know about Tesla, but *Your* stock just went up!
😁🤭
You do know this is going to be plagiarized all over YT!?
HAHAHA! My head shall get no bigger than it already is, lol.
She was throwing so much into the conversation that I didn't get to clarify the bounds of that $65 dollar figure. It might be the cell level for Roadrunner?
Sulfur is a ways out. However, if they can show any progress on par with what they are doing with Lithium Metal, it will be huge. Lithium Metal with Sulfur would be beast mode!
🤔 For large vehicles, a hybrid system makes more sense! Hmmm, or would that be the other way around. I'm not sure.
It sounds like 400 is in the bag for 2025 Tesla vehicles (3-4 years plus Elon time). If so....holy sheeet.
Yeah, I hope all the email she gets won't dissuade her from future interviews, lol.
@@thelimitingfactor
I was hoping for $85 at cell level.
It would reinforce my belief that Roadrunner will be the primary cell for automotive applications......?
Sulphur, I agree.
The combination? 👍
"400"?
Still expect 300+ soon.
As long as one of the emails she gets is from Elon.....😁
@@thelimitingfactor $65!!!! Great I was speculating $75 or lower based on Semi prices. Note to self. Get more $TSLA.
@@srikanna4597
I hope you timed it right! (TSLA)
@@rogerstarkey5390 Doesn't really matter in the long run, but yeah. $382
*Dr. Meng* Incredible. An Intellectual Wonder Woman Incarnate. Thank you!
I love this channel so much! I probably understand like 10% of what is being said but its so cool!
It's okay, that's probably about how much I understand when I'm talking to researchers, lol.
One of the best interviews! Shirley is such a smart, positive, and likable woman! 20 years time to save our planet, not more!
Great interview Jordan! I have come across Shirley on some webinars so ....what a scoop! Congrats!
You keep taking ur interviews and content to the next level each time! And we're the better for it!
Thanks! 🔥🤜🤛
It was surprising to me that most of the benefits of silicon already come with adding 10-20% to the anode, while transitioning to 100% silicon seems way too challenging in relation to the then smaller reward. Thanks for getting this kind of information out there Jordan!
I suspect this is due to to big cathode footprint, and would become more important with a metal cathode.
Great Jordan. Thank you Shirley.
Blown away... again... just 2 days after Sila's Future of Energy whitepaper, everything the content, Shirley, the timing, blown away
It's coming thick and fast! I have to update my Battery Day script every day, lol.
@@thelimitingfactor Love it man, absolutely love it we need more of you in the space
Great interview. Enjoyed the conversation too... wasn’t just Q&A. Loved Shirley’s answer to the last question.
Professor Meng is such a lovely person. And so intelligent as well. A delightful interview. Thank you.
Meng so impresses me. I feel she must have had a sparse beginning, but got her educational break early on - I'd be curious of her life story. She is a gem of personality & enthusiasm & her birth-graced brilliancy potential must have become visible early on in her education. Amazing & lucky to have teachers like her whose work bears the fruits of her visions!!!
wow that was outstanding!
Love these videos! Thanks for uploading deep dives into hard to compile/understand topics. TH-cam is often surface level and sensational. This is very informative.
It was a real honor interviewing her and it was really nice to see the community enjoy it!
You're a naturally good interviewer but there's something else --you KNOW and freaking LOVE the topic. These two factors provided great synergy between you two. There is absolutely NO way a "pro journalist" (turns head and expectorates in total disgust) could ever have made a video these worthy and detailed. This video was simply FANTASTIC.
Thanks man! 🔥
Finally, the hype of “ten times increase in energy density” deflated with simple basic chemistry at the very beginning. Thank you.
Yeah, it gets frustrating doesn't it!
I did not understand the explanation. Of course what carries the charge is still the lithium. But if the accepting matrix were 10x more effective in silicon, then that portion of the battery can be made that much smaller... no?
@@earnmyturns6305 Think of it this way. There are 6 parts to the internals of a battery (cathode, anode, electrolyte, Al foil, copper foil, shell). In order to get 10x energy density, all of those parts would each have to be 10x more energy dense.
Making only one of them 10x only doubles or triples energy density. But, in reality, it doesn't actually double or triple because there are even more factors. I've done other videos that explain why Si loses energy density...like the moonshot video.
This lady deserves a Nobel prize!
What a fantastic video. Thank you both. The exciting part for me was having validation that Nano Silicon is the answer because HPQ SILICON has developed a cost efficient way to produce spherical nano silicon and they said they can tailor the size to suit the client. This is exciting because from what I understand cost has always been the limiting factor for not using nano silicon. It will be exciting to see what Tesla can do with it!
That was wonderful! Made me tear up at the end. I would love to see another interview with her in a year. Make her a regular!
Her comment about graphite and battery demand was the most juicy tidbit for me. It's so true. We're just getting started with electrification and will continue to be battery constrained with no end in sight.
I was really happy to show another side of battery research(ers). More of a human side. It helped so much that she was easy to interview. In due time, will do another interview.
A simply terrific interview. Superb questions. Shirley is a top leader in this industry and wonderful to hear from her directly. Thank you both for doing this first class interview.
Great interview congratulations in being persistant and accurate and getting the interview with Prof Meng
Sixteen months after this interview it is still very useful to review and deepen my understanding of the development of battery technology.
Incredibly insightful interview and responses by Jordan and Shirley!
😊
Big score getting such a qualified guest.
Graphite curiosity brought me here. So glad I found this priceless interview. Sincere thanks to both of you.
This is absolutely amazing! I don’t know how your viewer demographic is, but as a mechanical engineering postgrad, this sort of content is exactly what im looking for.
Mostly engineers I think, lol
As someone with a masters in creative writing, I'm barely hanging on through most of Jordan's videos, haha. But I'm willing to bet there are many other viewers for whom this challenging new information, and not just review. One of Jordan's greatest strengths is making things more understandable.
@@adrianfortmoviereviewsbook9821 You are not alone 😂. I've tried watching videos from a few months back to relearn things that had slipped. I had to rewind and replay a few times.
@@thelimitingfactor
Regarding "replays"
That makes me feel much better!
Or, at least, "less inadequate"...😁
The Limiting Factor does a computer engineer count?
Damn its hardly been half a year... look at you goooooo!!
I learned about her through your video before I realized she's a professor in my department lol. A year later, I just finished taking her thermodynamics class
Fantastic interview. And what an uplifting personality. Her optimism and enthusiasm is infectious.
Thanks for setting up this interview. Shirley Meng is great; I would love to be a 20 year old who stumbled into her 101 class.
Thanks for the great interview, Professor Shirley explains the complex ideas very well and makes them a lot more understandable.
Very exciting content! Can’t wait for the future! Thanks Shirley!! Thanks Jordan!
I LOOOOOVE IT! Moore’s Law for batteries is annual storage capacity produced!
Dude! Great job getting an interview with Professor Meng. Please Please ask her back for another interview. I think your channel's deep dive into state-of the-art battery technology helped clarify that there is so much more room for EVs to gain a significant competitive advantage over ICE vehicles. I hope you can get her back to discuss battery research optimized for grid base storage. Keep up the wonderful work! Wow - $65/kW-hr means a 200 mile range compact car with a 50 kW-hr pack can cost less than a Toyota Corolla!
Sure thing! I think she's up for another interview. Just to clarify, I think she meant $65/kwh at the cell level, which is $100/kwh at the pack level. I'm guessing below $70kwh at the pack level will be Tesla's next target though. 😀
Wow she's awesome ! I can listen to her for hours explaining batteries :)
Jordan, what a "scoop"! An incredibly informative interview, with a world class expert, who is a wonderful communicator. An honour - thank you, Eamon
Thanks for the support Eamon!
ok. now i get it. she explained the stuff i was looking for in the first 2 minutes of the conversation. :-)
I was hoping for this interview to happen, great stuff!!
Thank you for making the videos.
This was so good. Please do this again!
This was Gold, thanks for setting up this interview :-D
Dang!! One of the best interviews ever on battery technology. I love how you react on the passionate expose of professor Meng with a stoic ‘very exiting’. You rock man!
So so good! Congratulations and keep on going!
VERY informative. The intellectual joy you felt speaking with Shirley was obvious. Your best interview to date.
Thank you both for your time and insight
Great interview!!! Excellent.
Great interview! Thank you for sharing with us.
Congrats on the great interview!
Truly excellent content. Thank you to you both!!!
Very informative & a great interview!
So much rich information here. Thank Ya'll!!!

Great interview, fascinating topic, thanks to both of you👌🏻
Great interview from both of you.
Thank you very much for getting us that interview with Shirley
You're most welcome!
amazing interview! thanks :)
Very interesting interview!! Well done 👍
Really good stuff here. I learned a lot and am excited about silicon anodes!
Man good job, I have seen Shirley Meng's name pop up quite a few times but haven't seen her talk. Very informative interview to say the least, thanks for having her on.
Excellent work. Thank you!
Great questions, great interview on both sides. Thank you for the quality content.
Thanks for your efforts Jordan. Great guest and interview.
I loved this. She is so easy to follow.
Inspiring! Exciting,Optimistic future!
Great interview thank you. Thank you Professor Meng!
Excellent, really enjoyed that! Cheers
Great to see a Professor talking about stuff that is likely to be commercialized, not just lab samples.
That was great. It felt like a mini battery class. It really gave me some valuable insight into the state of battery tech. Thank you both.
What a wonderful video. I only get optimistically half of the conversation but regardless a fantastic insight into the state of things.
Wow more Shirley Meng please
What an insightful and interesting interview. Thank you so much for your efforts in bringing this more into the mainstream.
Thanks for the info..👍
