WEBFI-TECH-How a Lithium Ion Battery Actually Works // Photorealistic // 16 Month Project

How does a lithium ion battery actually work and what does it look like at every level of scale from the atom up to the cell level? That’s exactly what this video will cover in photorealitic detail after 16 months of animation design.

  • The Limiting Factor on November 28, 2021

    Interesting factoids and clarifications:

    1) Although the electrons can travel at close to the speed of light, the rate at which the battery charges and discharges is often limited by the speed that lithium can travel between the electrodes through the electrolyte solution. When the battery is fully charged, the nickel oxide is starved of electrons, which can impact the lithium ion motion.

    2) "Like a drop of ink dispersing in water." Lithium ions diffuse through a liquid, but there's a bit more going on here. The concentration gradient drives the lithium ions to the opposite electrode and is strengthened by the electrical field between the electrodes. That is, it's as if the ions are being pumped from one electrode to the other.

    3) "When an electrical pathway opens between the anode and cathode, all the electrons between the cathode and anode sense the energy imbalance." What I'm referring to here is the complex dynamics of the electromagnetic fields that flow in and around the the electrical pathway between the cathode and anode. I anthropomorphised as a shortcut because electromagnetism would be another video entirely.

    4) I used the chemistry definition of electropositive and electronegative in this video, which are different from the physics definition.

    Absolutely amazing piece of work!

  • Chad on January 8, 2022

    Wow literally the best explanation I’ve seen. Thank you

    I will be sharing this as much as possible and rewatching it every few days to gain a better understanding. Even if this doesn't get as many views as it should, know that this video is something to be extremely extremely proud of. This is possibly the best piece of educational content I've ever seen and I'm confident it will inspire at least one person (maybe even me haha) to start a career in battery development. Who knows what ground-breaking innovations will be caused by this video. Thank you for the immense amount of work this video took and for making it available for free. I will be supporting you financially in the future, but unfortunately it may have to wait until I'm not a student. I can't wait to see what else you make!

  • Pritish Bose on January 9, 2022

    Such a complex amalgamation of physical and chemical concepts summarized in a 17min video with amazing visualizations and graphics. Undoubtedly the best one out there. Thank you for the effort! Keep up the good work.

    Electrolytes. It's what ions crave.

  • David Morse on January 9, 2022

    Jordan. Chapeaux; Sir!
    Do you now have enough positive comments; to justify finally going for that “dream of doing this full-time”?
    You will get no firmer indication than the wonderfully supportive and positive comments in this thread. Do it!!
    The world needs you to fill this information gap with your unique knowledge, talent, style and clarity.
    You were born to do this, Sir! 😍💪🏼🔋

  • Mark Hancock on January 9, 2022

    Great video, thanks.
    I am an Adjunct EE instructor at a local University. Videos like this help me to answer side questions my students invariably ask.

  • Electrified Veronika on January 10, 2022

    Amazing video! Best one I have seen so far to explain how batteries really work! Congrats!

  • Marin Markelic on January 10, 2022

    For the algo

  • Kappa1000 on January 10, 2022

    Of course it's fabulous Jordan! 😀

  • Michael Blosser on January 10, 2022

    I hope you all understood what he was teaching here because I sure didn't! You guyz way too smart for me

  • Peng-Wei Chu on January 11, 2022

    Best video on this topic so far. Would love to see more like this.

  • Tino Chami on January 11, 2022

    this is an amazing piece of information I wish to donate if possible

  • Bo Henriksson on January 11, 2022

    Gorgeous animations and perfect narration! Well done – and more please!

  • suraj tiwari on January 11, 2022

    Make a more detailed video on this, incorporating ur clarifications with animation

  • w23857980 on January 11, 2022

    shit happens

  • Physics Radiate on January 12, 2022

    Great work

  • 栗子酥 on January 12, 2022

    This is better than any college course I took back then. Great content!!! This should be the way to teach everything.

  • Derek Elliott on January 12, 2022

    Awesome video! Unbelievable you aren’t getting paid a professional salary for this high-quality content. I’d suggest spending a day figuring out how to enable YouTube Donations and Twitter Tips, even if you need to spoof your location using a VPN. I know I’m not the only one who wants to contribute to your work without using Patreon as the gatekeeper, thanks again!

  • Matej Štulák on January 13, 2022

    Thank you, really well explained. Conscise clear to the point and a bang on visualization to complete the picture. Best piece on the topic I have seen period.

  • Arthi Gopalakrishnan on January 14, 2022

    It was such an amazing video for research starters in the field of LIB. The explanation of mechanism was neat and clean.
    It would be great to see how Li ions would lead to short circuit in abnormal conditions, explosion of batteries.

    Thank you for the great video.
