I m learning blender for my unity fame development purpose but to learn i would love to make such animations.. anyways thanks both of u guys for such amazing animations..
As an Electronics Engineer, i greatly commend this channel for making outstanding videos on electronics,, You deserve millions of subscribers... Great work
This is literally exactly how I pictured the perfect tech videos to learn about stuff. Great colorful visuals, and simple but detailed explanations 😍 (I'm working on a few far out energy storage things to be made at scale, right now, but so far I dont have anything worth sharing to the general public at the moment but stay tuned if you want to hear about some exciting news)
Question: "I learned that the Anode is + and the Cathode is -. Why do you say the reverse?" Answer: Well, in electronic devices, by definition: the anode is where electrons leave the component. In a diode or LED, the anode, the anode is the + terminal, the cathode is - and current goes from + to -, and electrons go from - to +. However now, think of the battery that is powering that LED. When operating, electrons come out of the negative side, and by the definition that makes this the anode. Thus, for batteries the anode is - and the cathode is +. But, chemistry uses a different definition of 'the cathode is where species are reduced, and the anode is where species are oxidized'. And for a battery function vs recharging the anode and cathodes switch sides, but + and - designations stay the same. TLDR: Anode and cathode are defined by more than just Anode is + and cathode is -. Discuss your answers to the 3 questions here: 1) Why Lithium? 2)How can we improve upon the Li-ion battery? 3) What are some far-out dreams for the next evolution in energy storage?
Storing energy using some kind of energy-cells which is made for injecting them into our blood vessels so the blood flow will power every installed electricity-requiring augmentation. I got this idea from Deus Ex: Human Revolution. And get rid of Neuropozyne requirement ofcourse (it can be achieved using Adam's DNA :-)).
Glad you liked the video, really the best way to help is to share the video. If you want to help further drop an email. You can find it on the about page.
Wow, I worked in a development lab making automotive Lithium Ion batteries for 10 years. We coated the carbon onto the large aluminum and copper “sheets”. We cut them to the proper size, wound the layers together (including the separator), put them into the final package and filled it with electrolyte, tested them and many times integrated them in to larger battery systems. It was fun. The chemistry always seemed to be a black art that only the Phd chemical engineers understood! This was good video.
The chemistry is so confusing because it’s wrong. Electrons are not these little balls that travel from one spot to another. They’re discharge from the protons which produce waves that we call current.
Thank you so much for making these informative videos! The visual aids are a useful aid in gaining an understanding of these brilliant devices. I have a question: if the cobalt shares its electrons with the oxygen (which is what happens when you form a molecule like cobalt oxide), why is it so eager to accept electrons from the lithium?
That question is really the underpinning of Chemistry. It's an involved answer, but the short answer is that some elements want electrons more than other elements
This is why I enjoy these videos. I had a misconception of the positive end being green and pushing electrons to components, I was so wrong! I learned that the negative goes to the phone and comes back to positive (cathode and anode) all the information was really cool and well presented. Animations make it easy to visualize and understand. Keep up the amazing work!
Best explanation ever, you know why? You explained even the chemical reaction with half's reactions also.That i was searching for.Thank you for the video and info's.
Everything is so thorough, with the spatial animations tying it all together😍 This really helps me understand concepts that are usually very difficult!
I will never look at charging my smartphone the same again. P.S. Your video was awesome and so incredibly easy to understand. Looking forward to seeing everything else you have.
Great video! One note. Li-ion batteries can be safely discharged under 30%. The device will turn off at terminal voltage (around 3v) and reduce the rate at which lithium leaves the carbon. After a while in this state the battery protection FET will kick in (in the 2.5V range) and leave only self discharge. In other words: don’t worry! Drain to zero but don’t leave it there for too long (months). Also, don’t charge it to full and leave it in a hot environment (say over 35C) for and extended amount of time because that is bad. Charging at cold is worse but the device (software or hardware) should prevent that.
so interesting! what happens if it’s charged but left for months? and why is it bad to charge it when cold? (i’ve heard electrons behave differently at lower temperatures?)

Pay attention at school and actively engage in your learning and that will change for the better. Stop being a terrible student who thinks the teacher must pander to you.
No detailed yet to-the-point video at the same time, can be possible than this one! Thanx a lot for such a lovely content..! The channels like this, are the jewels of RUclips...!
Do you not think the actual battery percentage showing on the phone screen is on a recalibrated scale? I mean phone 0% is equal battery 20-30% and phone 100% is equal battery 90% to protect the battery by the manufacturer?
what an incredible video, and beautiful animations. The effort put in is outstanding and a pleasure to watch this channel with definitely grow bigger, keep it up!!
This is one of the best or probably the best illustration video I have seen describing how Lithium Ion batteries work in phones and devices. Excellent!
Your way of sharing knowledge is just amazing. Keep doing your vids, they are incredible. About the battery, I have to ask why is there a last separator and electrolyte on the animation, if it does not go in the process?
It comes in play when you fold layers over on themselves. Take 2 sheets of paper, label them, and then roll them up, and ya find that you need an additional separator on the outside.
At First, I have to say thanks for this great video. and about the question 1: Because we know that metals desire to give up electron. So the electrons can easily get out of the battery and be used on different part of the phone. About question 2: Maybe we can put these layers on a circle and make them smaller but more, So we have an electron which is getting out of the lithium and use in phone and back to the cobalt and right after that it will go to next layer which is again a lithium and do that again and again. About question 3: We know we can get energy from light, temprature, maybe sound , and... . So maybe we can use things inside the phone to collect them and use them instead of charging the phone again. And actually I have question too, It's great to use Lithium for the first layer because it's a great metal but they are using Cobalt in the second layer, I mean if they use something Non-metallic it will take electron better and it may improve the battery, So why don't we use something Non-metallic for the second layer? Thanks for your great videos.
Superb explanation. Now I learned, How our smart phone batteries degraded over time. Thanks a lot making such easily understandable animation video. Respect.
For anyone confused by why he's describing the flow as going from negative to positive, look into the Conventional Current Flow model, vs the Electron Flow model. The conventional model (which is standard in electrical engineering) states that flow of electric charge is considered to go from the positive terminal of the power source to the negative terminal. This model was created before the discovery of the electron, and after this discovery it became known that the electron is the primary carrier of electric charge in most materials. Electrons, being negatively charged, move from the negative terminal of a power source to the positive terminal. This flow of electrons constitutes the actual movement of charge. Overall, the conventional current flow model remains the standard in electrical engineering due to its historical precedent, mathematical convenience, compatibility with existing knowledge, and practicality in engineering practice.
@@BranchEducation please make a video or explain how mobile chargers pull the electron to the opposite side.. Cause cause i've seen a several video where they said chargers just convert ac to dc. But no where mentioned as you mentioned about the job of charger. So please explain
7:11 this also protects the battery from not just over charging, but also over discharge, short circuits, amongst many other very bad things that can damage or cause the battery to ignite/explode
Well done, you are doing an amazing job. Please do not give up, you are making high quality content and you will get the appreciation that you deserve.
The statement of "charging the battery when it's on its 30% or 40% charge" is correct. However, due to the technology advancing constantly, modern phones have a system implemented in place so that it won't allow the phone to discharge all of its juice at once. The phone will turn itself off before that happens to reserve the remaining charge, so you don't run into those issues in the future. There is really no need to worry about that issue anymore, unless if there was another issue with the battery. Sometimes, constant changes in current or using the wrong charger with the wrong voltage and ampere can also affect the life and performance of the battery
As a retired Met. O. Instrumentation development scientist, I can highly recomend this video. Even reinforced my understanding in places. Nice one put in an easy to follow format for the non technical among us.
1) Lithium ranks up higher on periodic table, it's a small atom therefore you can store more of it in same space as other materials on top of the other necessary characteristics. 2) Solid state is exciting. Teslas dry electrode tech is exciting. Silicon to replace the graphite and Li air batteries I've also heard of but I don't know enough detail. As far as better answering the questions I'm really stoked about Teslas dry electrode tech well it still belongs to Maxwell for now. They realized that production processes from capacitor could be applied to Li batteries. The way all the different sheets are bonded is using a wet bonding agent and then the sheets have to be laid out and dried and heated. Using a powdered dry bonding agent once can cut down on manufacturing cost, time and huge amounts of factory floor space. The resulting battery is also a little more energy dense (gravimetrically but probably also to an extent volumetrically) and has quite a bit more power density (20% I believe) because the wet bonding agent remains are restrictive, and being power dense of course will lead to higher charging speeds and higher power output. 3) I have a far out idea. Not quite energy storage but transmission. There are already solar cells tuned for specific laser frequencies but I wonder if we can have a very powerful laser transmit energy thermally straight into a reactor core to speak. It would have to get through a shielding material inside into some agent like a molten salt type that can absorb the laser and heat up well. It would be super inefficient but the receiver could be very power dense maybe enable electric high performance flight. Okay E storage how about antimatter. We can already make the stuff in small quantities we should figure out to scale that stuff and fly to the stars with massively powerful ion thrusters.
Here in video shown that by using charger electron flows reverse direction so but here by changing not new electron adding??? If not here no use of extra electricity???? Please explain....
Give me a timestamp so I know which moment you're talking of. But when charging with "electricity" what that means is think of it as if we're adding force (voltage) to the electrons. We're using the force that comes from a generator in a powerplant somewhere to move the electrons in a circuit that would've otherwise just stood still. In the case of a battery we move them to the graphene side in order to restore the electrochemical potential.
@@ryccoh First of all thank you for your interest in helping🙏 So if electron not added then how other daily instrument we use such as fan how electricity flow??? And if in this case only voltage difference are generated so how circuit closed path is occurs??..
Amazing video! I have jus a few questions, How many cycles has a Li-ion battery in general? Or it depends on the manufacture? When the battery lose cycles and what we can do to avoid it?
You haven't addressed how the device is able to work while being recharged. Is the inverse flow of electrons able to power the device? Is there a buffer battery with a small capacity that drains while the charge is ongoing?
Brilliant....absolutely brilliant video. The best, clearest, interesting explanation of lithium battery operation. Not too much info but sufficient enough to give the watcher a solid understanding of a technically mysterious subject! Well done. Animation was excellent and helped massively for clarity.
Don’t get me wrong, I absolutely love this channel, and I have no doubt that this video would be an extremely useful resource for someone coming in with little or no prior knowledge on the subject. With that said, this video unfortunately left me with more questions than answers. I understand how batteries work at the conceptual level described in the video: for instance, I know that when you plug your phone in, electrons are pumped back to the graphite and thus the lithium ions with them; what I don’t know is how that is accomplished. Another example would be the “additional electronic components” between the battery itself and its external terminal connections - the video simply states that these components do things such as prevent overcharging; how is that accomplished?
A lithium ion battery is more often referred to as galvanic cell . Where the anode is negative and cathode is considered positive. While in electrolytic cell anode is positive and cathode is negative.
Cathode and anode terms interchange in case of the things that use electricity and the things that produce it. Eg. CRT(runs on electricity) and Battery ( produces electricity).
There are many doubts about electricity that do not get solved in my school. Since I am interested in science, i question even the smallest of the things. This channel has helped me to understand the smallest of the concepts and has answered most of my questions. Thanks man!!
Worth it....I got phone with 5000mAh...and I would advise all the viewers to charge their phone only between 20-80%... does causing less stress on anode and cathode plates
As someone who spent a decade in this industry, I have to say this is a great video to explain exactly how all this works. I wish this video was around when I started, reading this stuff on paper fries your brain!
Can you perhaps explain why exactly the ions also want to migrate after giving up electrons? And I don't understand how literal atoms (ions) travel through a substance like that almost like a gaseous substance? Thanks!
If you have a smartphone that has a removable battery, youll see that there are 4 pins for energy exchange. Yep, both process are running at the same time
Really loved the content explaination and the depth is really what i want. Very knowledgeable, I just began yesterday night and by the i have watched more than 10 videos continuously Pls. Keep making such videos Salute sir And appreciate ur efforts . Might u reach heights
Absolutely amazing video! Laid out very well. Going to have to rewatch a few times to try to get this to stick. So why fold the battery like that? Why not have the 3 main components, but just thicker? Since for some reason it must be advantageous to fold it, what are the limitations to it? What stops manufacturers from going even thinner? Some sort of emf interference? Limits because of atomic level geometry? Maybe just diminishing return on investment? Thanks!
These are great questions. Definitely one reason for the folding is to have a higher available Amperage at any given time. So once you hit a threshold that you don't need any higher Amperage. then why not fold it thinner? Definitely, one drawback is that, sometimes dendrites form from the Anode/cathode. These are little 'spikes' that if they grow long enough, can potentially make their way through the separator and destroy the battery. This is definitely a reason why you don't want to get too thin.
This is the first illustration that I have watched on this topic, and I do not think that there is simpler and clearer than that. Thank you very much for spreading the knowledge.
Thank you for the video I learned a lot, but I have a question: why do certain operations on the phone, like playing a game or watching a video, consume more electricity from the battery, how does this process look like?
I think when we charge the phone, the amount of electrons that move from the charger to the minus side, is more than the electrons moving from the minus side to the positive side and that's the reason why the charging percentage keeps going up despite using the phone at the same time
@@sunrayseducation I've read that it's better to leave the smartphone aside while charging but if you use the original charger, it's not gonna make problems for the battery
It would be most ideal if your charger charged slow enough so your battery does not charge, nor drain...and you kept your battery at 66%...while you're using your phone.
Tyler Durden So do the charging and discharging process operate in tandem, or do they use the same system and mix the flow of electrons into and out of the negative side?
Using your phone while charging draws power from the battery to power the screen and other components. The competition between the usage and battery charger supplying charges causes your battery to overheat which will damage it in the long run
I have one doubt 🙋. When I was studying electrochemistry, I learned that electrons enter through the positive terminal which is named as anode and come out through negative terminal which is named as cathode. But here in this video the naming was different. Why?
Great question! An anode is defined by the terminal with which the electrons leave a device. Next consider how electrons flow in a battery, a supplier of electron flow. Vs a smartphone, a consumer of electron flow. Finally consider the requirement to hook + to + and - to -, otherwise it would confuse users. Think about the discrpency.
Correction. That circuit on top of the battery has multiple functions. Prevent overcharge, prevent complete discharge. The user doesnt have to worry about the phone going to zero (0%). The zero (0%) on the phone could be 20% or 30% on the real battery depending on specs. The same way full charge (100%) on the phone could be like (90%) on the real battery.
All your films are the best ! It is so important to understand it, and you provide the information in very clear way. Often much better that teacher at schools (unfortunately). Thank you !

If not here no use of extra electricity????
Please explain....
Electrons are never added in a circuit they just get moved.
@@ryccoh
Yes you are right
But in this case why we use electricity if electron is not added???
Give me a timestamp so I know which moment you're talking of. But when charging with "electricity" what that means is think of it as if we're adding force (voltage) to the electrons. We're using the force that comes from a generator in a powerplant somewhere to move the electrons in a circuit that would've otherwise just stood still. In the case of a battery we move them to the graphene side in order to restore the electrochemical potential.
@@ryccoh
First of all thank you for your interest in helping🙏
So if electron not added then how other daily instrument we use such as fan how electricity flow???
And if in this case only voltage difference are generated so how circuit closed path is occurs??..
This was really useful. The battery inventor was a smart person
Thank you so much for the video as most of the videos in your channel are what I'm searching for a long time. Keep doing more. Subscribed. 😎
Thanks! What did you think of the other videos?
Li Ion battery basic principle is explain very nicely and in a simple words. I have seen many videos and clips, but this video is amazing.
Amazing video! I have jus a few questions, How many cycles has a Li-ion battery in general? Or it depends on the manufacture? When the battery lose cycles and what we can do to avoid it?
You haven't addressed how the device is able to work while being recharged. Is the inverse flow of electrons able to power the device? Is there a buffer battery with a small capacity that drains while the charge is ongoing?
First time I understood the meaning of electrolytes! 👍
Same!
Brilliant....absolutely brilliant video. The best, clearest, interesting explanation of lithium battery operation. Not too much info but sufficient enough to give the watcher a solid understanding of a technically mysterious subject! Well done. Animation was excellent and helped massively for clarity.
Please keep making these videos !
They are really awesome !
These animations are just whats needed to visualize these magical processes and components. Thanks a lot, hope you continue doing the Gods work.
5:54 galaxy note 7 cough cough 😂
lol
It's not that simple man
It’s a joke
Rip
I remember it XD
Don’t get me wrong, I absolutely love this channel, and I have no doubt that this video would be an extremely useful resource for someone coming in with little or no prior knowledge on the subject. With that said, this video unfortunately left me with more questions than answers. I understand how batteries work at the conceptual level described in the video: for instance, I know that when you plug your phone in, electrons are pumped back to the graphite and thus the lithium ions with them; what I don’t know is how that is accomplished. Another example would be the “additional electronic components” between the battery itself and its external terminal connections - the video simply states that these components do things such as prevent overcharging; how is that accomplished?
This is a really great video! I would be very interested in learning how wireless charging works.
same thing but instead of cables it uses induction.
One of the rare cases that I subscribe to the channel with just the first video
I believe typically/conventionally cathode is -ve and Anode is +ve. When discovered as Kathoda and Anoda. Plz clarify
A lithium ion battery is more often referred to as galvanic cell . Where the anode is negative and cathode is considered positive. While in electrolytic cell anode is positive and cathode is negative.
Cathode and anode terms interchange in case of the things that use electricity and the things that produce it. Eg. CRT(runs on electricity) and Battery ( produces electricity).
There are many doubts about electricity that do not get solved in my school. Since I am interested in science, i question even the smallest of the things. This channel has helped me to understand the smallest of the concepts and has answered most of my questions. Thanks man!!
Made in blender ❤️,,, This looks like a lot of work for you,, such a great animation and explanation too, thank you
It seems you have placed a lot of hard work making this video. Nicely Explaied. Keep making such videoes. Really Informative.
These videos are so will made. I love when you go into the most basic of the basic stuff
This is most concise explanation about Li-ion battery I have come across.
Worth it....I got phone with 5000mAh...and I would advise all the viewers to charge their phone only between 20-80%... does causing less stress on anode and cathode plates
Thanks for the information. I always wondered what the ideal battery levels were to make sure your battery lasted longer.
8:31
"to make a battery you just need three materials"
*proceed to label 8 different parts of the battery*
As someone who spent a decade in this industry, I have to say this is a great video to explain exactly how all this works. I wish this video was around when I started, reading this stuff on paper fries your brain!
Can you perhaps explain why exactly the ions also want to migrate after giving up electrons? And I don't understand how literal atoms (ions) travel through a substance like that almost like a gaseous substance? Thanks!
Thanks for helping me understand something perfectly that I randomly got interested in the middle of the night
So what happened to the current/flow when we charged it WHILE using it???
pikaboö nu Back and forth happens. Unhealthy for battery life.
The current runs in the opposite direction and makes no different I guess...
If you have a smartphone that has a removable battery, youll see that there are 4 pins for energy exchange. Yep, both process are running at the same time
@@UniformDelta00 nope, they have just 3 pins
@@raviverma8479 I expect different technologies from different smartphones. We may be both right.
Really loved the content explaination and the depth is really what i want. Very knowledgeable,
I just began yesterday night and by the i have watched more than 10 videos continuously
Pls. Keep making such videos
Salute sir
And appreciate ur efforts . Might u reach heights
Very good video really enjoyed it keep it up bro
Best video in the world in order to understand simply how lithium ion batteries are working!
Such high quality videos! Awesome!
Easily the best education related video I have ever watched !
Absolutely amazing video! Laid out very well. Going to have to rewatch a few times to try to get this to stick.
So why fold the battery like that? Why not have the 3 main components, but just thicker? Since for some reason it must be advantageous to fold it, what are the limitations to it? What stops manufacturers from going even thinner? Some sort of emf interference? Limits because of atomic level geometry? Maybe just diminishing return on investment?
Thanks!
These are great questions. Definitely one reason for the folding is to have a higher available Amperage at any given time. So once you hit a threshold that you don't need any higher Amperage. then why not fold it thinner? Definitely, one drawback is that, sometimes dendrites form from the Anode/cathode. These are little 'spikes' that if they grow long enough, can potentially make their way through the separator and destroy the battery. This is definitely a reason why you don't want to get too thin.
@@BranchEducation what is the cause of this spikes building up?
This is the first illustration that I have watched on this topic, and I do not think that there is simpler and clearer than that. Thank you very much for spreading the knowledge.
Answer to 1st question may be that Lithium ion are small in comparison to other ions which makes them suitable for movement..
Thank you for video.
Thank you for watching & posting an answer.
Jazak Allaah(thank u)
It help me a lot to complete my work....
May Allaah blesses you.....❤
Do a video on wireless charging
Just a guess, but it's probably just a bunch of electromagnet tech
It's simply just tiny transformers, transmit electricity through induction from the coil
"Do a video on wireless charging, please"
Thank you for the video I learned a lot, but I have a question: why do certain operations on the phone, like playing a game or watching a video, consume more electricity from the battery, how does this process look like?
What happens when we use phone while charging. Is it recommended.
I think when we charge the phone, the amount of electrons that move from the charger to the minus side, is more than the electrons moving from the minus side to the positive side and that's the reason why the charging percentage keeps going up despite using the phone at the same time
@@soroushsafarzadeh8321 no I mean is it a healthy practice or not, for a battery.
@@sunrayseducation I've read that it's better to leave the smartphone aside while charging but if you use the original charger, it's not gonna make problems for the battery
It would be most ideal if your charger charged slow enough so your battery does not charge, nor drain...and you kept your battery at 66%...while you're using your phone.
Tyler Durden So do the charging and discharging process operate in tandem, or do they use the same system and mix the flow of electrons into and out of the negative side?
Very informative. I can't stop thinking of this everytime I use my phone, hereafter.
What a well designed animation ! Hats off, really :)
I am a complete layman but it was so cool to learn about how the battery of the phone I am using works! Thank you.
lithium has the highest tendency to loose electron in all other usable atoms.
Best animation regarding the battery system I have ever seen
OHHHHHH so that's why its dangerous to squeeze a battery and that's why some liquid comes out. THat s crazy. Insane
Thank you so much, this was very very helpfull for my Physics project
Fun fact: more than 50% of people watching this video charged their phone during watching
Very true
Got me
I never charge my phone while using it lol
Im just trying to figure out why my longboard wont charge😂
@@toxophily9599Bro is reengineering the technology
Great video indeed! Thanks to the creator of the video. Positive terminal is anode while negative terminal is the cathode
How is it that I can use my phone while charging? It seems weird that the chemical reactions can be happening both ways at once?
idk thats probably why your battery has 4 contact points 2 for charging and 2 for use but thats just a guess
Question: 05:30 What exactly happens with electrons and ions flow, when we use our lithium ion battery device while it is being charged?
What truly happens to your device when your using it while its charging?
Depending on the phone's power management phone may run the power from charger or from the battery or even both.
Using your phone while charging draws power from the battery to power the screen and other components. The competition between the usage and battery charger supplying charges causes your battery to overheat which will damage it in the long run
U really deserve more subscribers bro iam very satisfied with the video
Theo life of my smartphone battery, at the moment is just at 3%
Me too 😂😂😂🤣🤣
OMG... what a beautiful explanation ? Thank you so much :)
I have one doubt 🙋. When I was studying electrochemistry, I learned that electrons enter through the positive terminal which is named as anode and come out through negative terminal which is named as cathode. But here in this video the naming was different. Why?
Great question! An anode is defined by the terminal with which the electrons leave a device. Next consider how electrons flow in a battery, a supplier of electron flow. Vs a smartphone, a consumer of electron flow. Finally consider the requirement to hook + to + and - to -, otherwise it would confuse users. Think about the discrpency.
This is THE video for anyone starting their journey into the battery world. Highly commendable video.
Thanks!
My Phone automatically touch work when changing charger I have changed same problem face
I am really ecstatic to know this in so depth. Explanation was fantastic. I thank you very much.
Correction. That circuit on top of the battery has multiple functions. Prevent overcharge, prevent complete discharge. The user doesnt have to worry about the phone going to zero (0%). The zero (0%) on the phone could be 20% or 30% on the real battery depending on specs. The same way full charge (100%) on the phone could be like (90%) on the real battery.
Underrated comment
Loved it!! Thank you so much for the detailed clarification. I didn’t understand it atall when reading it from the textbook. This truly helped.
This channel deserve more subscribers and views. Most of our youth are busy in wasting their time in TikTok and other social media applications.
it helped a lot in my studies thanks 😍😍❤️️
All your films are the best ! It is so important to understand it, and you provide the information in very clear way. Often much better that teacher at schools (unfortunately). Thank you !
I like the recap parts, animation, and careful but detailed explanations! I'm subscribing!
Awesome, thank you!
