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.

We thank Mr. Ravindra Kempaiah for his invaluable technical contribution for this video. More about Ravindra can be found at this link : scholar.google.com/citations?user=5d_qotUAAAAJ&hl=…

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.

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.

Thanks for the lesson. I clearly understand how the Li-ion battery works now. Such wonderful explanation. Hats off👏👏👏

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.

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

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.

Battery tech is a really exciting topic to keep track of. Will be seeing massive progress there sooner than we think

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.
