Lithium-ion battery, How does it work?
HTML-код
- Опубликовано: 3 июн 2024
- A portable power supply has become the lifeline of the modern technological world, especially the lithium-ion battery. Imagine a world where all cars are driven by induction motors and not internal combustion engines. Induction motors are far superior to IC engines in almost all engineering aspects, as well as being more robust and cheaper. Another huge disadvantage of IC engines is that they only produce usable torque in a narrow band of engine RPM. Considering all of these factors, induction motors are definitely the perfect choice for an automobile. However, the power supply for an induction motor is the real bottleneck in achieving a major induction motor revolution in the automobile industry. Let’s explore how Tesla, with the help of lithium-ion cells, solved this issue and why lithium-ion cells are going to become even better in the future.

Here we use one battery in starting so battery itself emit electron so in graphite side electron increase for two reasons one emitted threw battery and other from li
Is it true???????
You need to add higher tiers on your patreon page like a $50 and $100 tier in addition to everything you have right now. This is a great channel!

It's crazy how complicated all the things we use daily are. I try to have at least a casual understanding of a lot of things but damn, there are a lot of smart people out there making really smart things. Cheers to all the scientists past and present for working their asses off so I can have such an easy life.
Sometimes I wish I was smart 😔
Jacob, I believe most tech, is really an evolution. Ideas are build upon. One tinny tinny example. My grandfather invented the automatic choke for the internal combustion engine. As he explained it to me it was simply a bi-metal laminate, when heated up the to metal expanded at different rates, causing the metal to move or open up the passage for more air to enter the engine (before this time an engine choke was manual). An automotive coil is something sorta, kinda like a battery only it only charges up for a few seconds, then BAM it lets out its electronic charge that is more that what was put into it. To me it kinda sounds like magic.

The level of efforts taken for those animations is appreciable ❤️
Yes sir😊😊
Decades of research and development explained in just 10 minutes. Thank you.
For those wondering why the Li(+) ion and the electron in graphite do not react with each other: Imagine the graphite as an Oreo, in which the graphene layers are the cookie and the space between the layers is the cream. The lithium ions are only located in the "cream" and the electrons are only located in the cookie. Graphite is only electrically conductive parallel to the layers, which means that the electrons in a layer tends to stay and move in the same layer rather than going through the "cream" to get to another layer. So the electrons are not likely to touch the Li(+) ions, probably unless you put a VERY HUGE current on it.
Which thing is guiding them to go on seperate layers?
Not gonna lie you said Oreos and I got hungry and went to the store and got me Oreos and completely forgot to read the rest of the paragraph
Typical physics guy coming up with an analogy harder than the actual event lol
Won't the graphite repel the electrons even if they do come in contact?
@@Medellin31 Same, really want Oreos rn
Thanks for the lesson. I clearly understand how the Li-ion battery works now. Such wonderful explanation. Hats off👏👏👏
For some reason I read that sarcastically xD
This is THE BEST channel to learn concepts 😍
I know i would never find a better channel to explain this as easy as you did! great job !
It was a wonderful feeling to know at the beginning, Ravindra's contribution in making this video. We were batch mates during graduation... Google suggested this video based on my preferences... Thanks for that. My best wishes to Ravi... Thanks for making this video. It's useful.
This is incredible, well explained and important piece of information. Thank you
Waaaawwww , I used to have very bad chemical teachers during my school so I never understand chemistry. This video is what every one need it to understand Li-Ion battery and basic chemistry of battery. thank you very much
The way it was explained is amazing.... 👏👏
Battery tech is a really exciting topic to keep track of. Will be seeing massive progress there sooner than we think
When physics marries chemistry, a Nobel Prize is born.
But the father is computer
but the god is human 😂
Wtf is this genetical discovery?!
A very big thumbs up and so much respect and gratitude I have for this channel. The ease with which you explain everything is just amazing. So damn satisfied. I am going to tell one of your ex-Prof. from IITD about this channel, who is currently teaching in my university after getting retired from there, I am sure he will be so very proud. lots of love thank you.
This video is of an exceptional quality, clear without being childish, very comprehensive and highly illustrative. Nice work!
This is one of my favorite videos, the explanation for how these batteries work is very fun to watch!
I wish my chemistry teacher teaches me like this
Drop out and get an education through RUclips bro

This was a really useful video, thank you. I'm trying to learn as much as I can about portable battery technology as part of my dissertation project on portable speakers.
Merci pour cette vidéo Brillante ! Tout est expliqué et illustré de manière pédagogique et compréhensible. Excellente synthèse.
thanks for your great information.. i appreciate your precious time to make this videos
You always make the best-animated explanation.
There were so many concepts yet the video was made with clarity, great animation, pictures and information. Thanks a lot!!!
The best i have ever watched! Very clear! solved my longstanding puzzles
very well explained really ...hands up to all those who contribute in this video
Excellent lesson.. If I could only retain this awesome info... 👍
كل الشكر لهذا الشرح الجميل واتمنى ان تفصل أكثر حول الغشاء شبه النفاذ الذي يسمح بمرور ايون الليثيوم
One of the best channel on youtube, what an extraordinary way to explain complicated things so easily.
This video is so well explained!! I have been trying to understand how lithium-ion batteries work and this is the first video which is clear enough to make me understand. THANK YOU
I wish you have explained how the degradation happens in Lion batteries and why it is limited to 3000 cycles
And why it has shelf life time
Li ion sometimes chemically react in unintended ways. When this happens Li ion get stuck and will be unable to participate in the charge discharge process. This happens more with increase temperature and voltage. The Solid Electrolyte Interface is where this stuck Li-ion is deposited.
Not an expert, but based on what I've heard, but I believe the cell gradually develops internal pathways, a bit like tendrils within the cathode's structure. The result is reduced energy capacity.
Depends upon what exactly the number 3000 represents. I don't think they mean 3000 "full" charge cycles. That would indicate that a battery pack is sized for 300 miles per full charge would achieve 900,000 miles after 3000 charge cycles. I think 3000 is a bit misleading. The reality is that present Li-ion batteries are achieving only about 1500 "full" charge cycles before showing enough capacity loss for some applications to consider replacement. But thats still 450,000 miles and they won't be dead at that point but likely have retained as much as 70% of their original capacity. As such they'll still be considered good and will continue on until they reach 3000 cycles where the degradation will likely be severe.
@@Tron-Jockey You are confusing different Li-ion chemistry. NCA have 1,500 cycles to 70% capacity. NMC have 3000 cycles to 80% capacity and 5000cycles to 70% capacity.
@@kazedcat Wow, thats even better than I though. Thanks for the update. I was basing my comment on:
cleantechnica.com/2018/08/26/the-secret-life-of-an-ev-battery/
This is the best explanation. I had to read other explanations so many times to understand because they always missed some key information. Thank you.
Brilliantly made, simple yet detailed and profound.
First time I basically understood a lithium ion battery chemistry . Thank you !!
Thanks for your video ☺
Very informative and clear demonstration of an intricate mechanism, wish our chemistry teacher could teach us such a way.
This video is so explicit. Thank you
Great explanation in such a short time. The animation of molecular structure behaviour is superb. Great Thanks for your work...👍👍👍...
The frantic electrons trying to cross the separator was epic 😀
When the mosquitoes stop bothering you: 1:14
I would have become a lithium battery specialist if you were my teacher in school!! Clear cut explanation 👍🏻
Best videoto understand basic working principle of li-ion battery. Thanks a lot. You saved me today in my presentation.
This guy really knows his stuff. Chemical engineering is something that no one i know, understands. Incredible
1:57 Of the alkali metals, lithium has the most strongly bound outer electron. Caesium has the most loosely bound outer electron of all the elements. Lithium is used in batteries because of its high specific energy and relative commonness.
So simple to understand!! Thank you!!!
Superb Explainantion kudos to the creators!!
Major of the paytreon supporters are Indian.. ... We are very much Intrested by the animation and teaching style... Keep it up... 👍
I have always been a Petrol Head, but: I must say that the mechanics of the electrical drive will be much easier, once the correct formula is found.
I would like to Tank you for this interesting review.
Awesome just came across this. being a science student this channel is a blessing. Keep creating and spreading the knowledge. Great video and awesome channel.
for the longest time I was so confused about how this worked even after being in chemistry class thank you so much for making this understandable
Why can't all my professors explain concepts like this? This makes it so easy to understand and I can clearly see what is happening!
Thank you for that masterpiece presentation from a layman's level of grasping physics made simple. Keep up this good work.-muhoro.
Good video. Proper explanations and no annoying music.
I'm very blessed to have found this channel!!! Thanks all the creators of this video. They'll save uni students.

Thank you so much for this video!!! This is the most comprehensive and clear explanation on LI battery degradation!!!
Hey fella JEE aspirant who decided to learn something in a practical way today!
I saw the mechanism ,it was really illustrative .But there is a thing I constantly ponder about - the connection of cells together in series .Like I have seen many examples of cells (the non rechargable ones too)getting connected in series .But I couldn't apprehend as to why the potential adds up .I saw many explanations for it but they were all analogies (mostly of multiple water pumps connected together )But I am actually looking forward for a reason that illustrates this with the movement of electrons; the way you did.I would be really grateful if you could make a video on the movement of electrons ,and the summation of potential in the course,when multiple zinc carbon cells are connected in series .
Hey I know it;s been 3 years, but if you are still curious, do more research on how power is transferred between electrons. The water analogy is very common but flawed. In reality, electrons hardly move. They largely vibrate in place (except for a small amount of drift)
@@micahsilverman5284When you have water in a hose, and turn it on, the water that comes out is at the end of the hose. Hydraulic systems are good analogies for electrical systems, even for alternating currents, as some hydraulic systems also alternate flow to transmit power
@@ignacioaguirrenoguez6218 think about how a hydroelectric generator works, by turning a magnet which generates a current. The magnet and current source are not physically connected, but yet you are generating electricity. So if the electrons are flowing like in your example, where would they come from? There is no inlet source, only an outlet source. It's like, you can turn on a hose, but you can only pump so much water.
So if you're analogy holds, where would all the electrons come from? Obviously as soon as you lose electrons, your source quickly becomes highly charged, and the electrons would start flowing the other way.
Instead, electrons do not "flow" in the traditional sense, they largely transfer energy between electrons.
@@ignacioaguirrenoguez6218 also, you're evidence for why hydraulic systems are good analogies was simply to say that they are good analogies, that's a logical fallacy (circular argument)
@@micahsilverman5284 Nope, you try to sound smart mentioning fallacies but I didn’t make any logical ones, I said hydraulic systems are comparable because there even are alternate flow ones, which transmit energy without long distance circulation of fluid.
Wow.. what a animation
Great work
Nicely done! A lot to learn from your course.
gotta give credit to the engineerings out there.
Excellent explanation ! but I have 2 questions ;
-Does the solid electrolyte interface is still happens with the silicon or just works with graphite ?
-When the lithium ions want to go back to their stable form when load is connected are there any chemical reactions happens with SEI layer ?
For the first question, as i understood, i dont’ think graphite has any role to play. Its the lithiom ion passing through makes the protective interface. So even with Silicon, it should be the same.
Excellent animation and gave so much clarity on the complex chemistry
My gosh, this is a masterpiece, perfect animation, i wonder how difficult it wud have been to understand this widout this help
Very well done. A video explaining how the switch from graphite to silicon storage medium would increase energy density. Thanks from Texas. May Jesus Christ bless you.
Yes that's Amazing, 5 times more capacity, can you imagine

Hi, i am naif al shallahi

Welcome of you have questions
You are a pleasant man, Naif. That will take you far. If you wish, you may mail me here: 'clint_who' '@' 'yahoo.com'
There must also have an electric insulator thin layer to prevent copper and aluminum foils to short together?
Yep, bien d'accord
Or they need to apply the layers to both sides of the foils, which would result in a more energy-dense battery! I think very few do this due to the manufacturing issues with coating both sides of a foil.
I think that's what the separator is for.
Of course, and that thin layer are the separator
It's almost the same thing as high voltage capacitors which have aluminum foil and plastic wound up when I made my first Tesla coil on science project I used mirrors or pieces of glass and aluminum foil between the glass made of my own capacitor so that the static electricity builds up in the fall and it's insulated through plates of glass which separated the foils
Incredible way of explanation, animation made the complex subject very easy
Very interesting lesson, thank you so much.

Tragic is my story.

Thanks for the well-explained tutorial
Incredibly well explained. Thank you!

Watch for another 10 seconds and feel better.
lmao
wait five years you will be okay
Lithium should make you feel better
BIG SPOILERS
Really great video. This kind of detail is not there anywhere.
Such a beautiful explanation! Thank you.
Why don't the positively charged lithium ions pair back with the electrons when they are both in the graphite lattice?
Graphite pairs with all the electrons? But the narrator said that graphite does not participate in the chemical reaction!
I believe it's because lithium separated from the electron is more stable than lithium with electron.. thus, naturally it isn't possible. However though, lithium with electron IN metal oxide is more stable than lithium separated from electron, thus, they combine in the metal oxide. I hope it helps
Am a civil engineering but i was very Curious about it ..
Well explained thank u
Great sense to make understand about Li ion working principle. No one has put this much of description. Tq
Funniest part is: electrons going back to positive electrode and we are using the energy! 🤣
