[@VinSpacker]

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]

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?

[@ShellYoung]

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.

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.

[@alexpelosi]

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.

[@stephensnell5707]

You dickhead,charging to 100% is harmless(it will take up to 4 years for a Smartphone Battery to degrade extremely badly)

[@arashmohammadi8772]

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.

[@ryccoh]

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....

[@ryccoh]

Electrons are never added in a circuit they just get moved.

[@tmodi2145]

@@ryccoh Yes you are right But in this case why we use electricity if electron is not added???

[@ryccoh]

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.

[@xorbite]

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

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?

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!

[@BranchEducation]

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.

idk thats probably why your battery has 4 contact points 2 for charging and 2 for use but thats just a guess

[@chrisupton6190]

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

[@mlg_joe7]

What truly happens to your device when your using it while its charging?

[@abcidea8694]

Depending on the phone's power management phone may run the power from charger or from the battery or even both.

[@amitsrivastava9033]

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

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.

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?

[@BranchEducation]

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.

One of the rare cases that I subscribe to the channel with just the first video

[@mushenji]

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

[@weikiatteo]

This is most concise explanation about Li-ion battery I have come across.

[@RaphaCramer]

Theo life of my smartphone battery, at the moment is just at 3%

[@humanskeleton6278]

Me too 😂😂😂🤣🤣

[@bimihadz1068]

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.
