Sir can explain with animation how electric locomotive works because there is not any source I found to understand...

[@anonamemous6865]

People said Li-po is safer?

[@melvinsharty4417]

I have never developed interest in learning engineering until when I subscribed to this channel. Please keep more video coming. A great learning platform. Learning made simple.

[@Baigle1]

good for you man

[@wallyfender]

The Stanford battery was invented in 2007 it held 10x the charge of a standard lithium Ion battery by replacing carbon with silicone wires the to professors that invented the battery were planning production within three years until they sold the technology to an oil company. I recently questioned Stanford university about the battery they directed me to a site saying this company is going into production with the battery . The site looked as if it had not been updated since 2016 and there was not any information about production.

[@kamalhossain2267]

Explanation was so good, lucid, simplified and palatable to engulf easily with enormous information.

[@gbin21]

Wow, you guys are on fire with the uploads. Everytime I see a new Learn Engineering video I get excited!

[@ronin5420]

Most complete comparison and explanation I have seen about this topic, great video

[@josephaharon]

Can these batteries be recycled? Would love to see a video about that process

[@john34261]

i hope one day the batteries can be recycled safely that's probably the other part of making the batteries last longer

[@raghunathsinghrajpurohith4894]

Great to listen. OSM even lectures can't explain like this . Good teacher. Covers #all subjects so I love le. Tq

What's that pause at 4:07 LOL
Perfect vídeo as always
Thank you so much!!!!!

What do u expect? The video was made by a man.

I really like your videos. what software do you make in this video?

Nice explain! Thanks

thanks for you that let me get more knowledge of lithium ion ，but some phrase still don't reveal

Great video, thanks! You mentioned 3 important characteristics of batteries but isn't there are fourth one- charging time?

[@lollipopgamer4666]

Nice video bro you channel is best channel in technical explain.

[@Justin73791]

One thing I'm trying to understand from this video is what causes Lithium Ion Cells to degrade if you discharge them all the way? Also would storing the cells in a discharged state be an acceptable long term solution?

[@jemyl1944]

GOOD ANIMATION AND GOOD ENGINEERING

[@PsyMongazoid]

Well, it's given us a clear understanding that whoever made this video has a vested interest in Lithium-ion batteries anyway.

[@amardeepjadhav1310]

Thank you Sir

[@mohanvamsi1180]

Your videos are simply amazing that when I am free I always watch your videos so that I can gain some knowledge about the tech so every time I watch your videos I fell that I gain some practical knowledge that can be useful for my life anytime
Thanks for making such videos and the thing I mostly learned from your videos is about the communication process
Once in our college, we presented our idea about the security of people after the presentation our team was asked a question about the call or message processing then to correct our self your videos "UNDERSTANDING MODULATION" helped our team to understand about the transmission of calls and other messages
Thank you for making our minds clear about the topics that we are unable to understand from our team and make more videos to make lives more Tech Thank you for your support.

[@edinaldopereira2285]

It is incredible how batteries moves many things on earth!

[@ogdan1173]

Hello and what is your opinion with carbon acumulators?

[@What_I_Make]

I think this should have stated sponsor of Telsla with such a large amount of brand advertising.

[@anasmoustafa7286]

Great video, but just noticed that @ min1:45, the power source negative (-) terminal should be connected to cathode (Li-host) on charging the cell, while anode to be connected to positive (+) terminal.

[@TheXTR3MElol]

What about the potential of supercapacitors, which are currently only in their infancy stage of development? Far greater power density and longevity compared to Li-ion batteries as well as much faster charge rates, but currently a lower energy density. Perhaps these are the future. Also hybrid supercapacitors attempt to combine both Li-ion technology with standard supercapacitors technology to try and achieve a good middle ground in terms of power and energy density.

[@michap.fertig3656]

Steffan Morgan you mixed it up. Supercaps are superiour regarding powerdensity. But ofc, every advantage comes with a disadvantage, too. There will be no replacement, because both technologys have other advantages and thus other applications/markets

The future lies with all carbon cells. These are made from conductive inks derived from carbonising simple organic compounds like onions or apples. Check out the work of Dr. Robert Murray Smith. You might like also to research the Karpen cell which uses two different carbons :)

I'd like to hear more talk about how we plan to avoid potential lithium crises in the future as more and more things use it in their batteries.

[@MrAryan448]

What about the super-capacitor.
Why not we considering it for the future?

[@devilsoffspring5519]

Capacitors are much, *much* bigger and heavier than batteries that store the same amount of energy.
Capacitors have their uses, but bulk energy storage (such as for electric cars) is not one of them.

[@xenyatox9814]

Can you realise a video about auto-reload tires that works with friction ???

[@dnetne5508]

So if we leave our laptops on the charger it should longer battery's lifespan then previously predicted?

[@stuartsjalund6912]

yes, you should leave your lap tops charger connected to the system, recharging. the problem with this lap top battery is there is no direct connection to the battery but charge current goes through IC's so one never knows if the battery is fully charged or not. FYI, I used an ordinary lithium ion battery in a player and taking care of the battery, it lasted 15 years! Lucky? who knows? Many li-ion batteries have a built in regulator and when it fails, you loose the battery too, even though the battery alone is probably ok. In reality regulators are not required if you know what you are doing and should be charged hot off the power diodes with no filtering or regulating. Even though the battery itself does posses some capacitance and cannot be avoided!

[@dnetne5508]

Thanks!

[@Complete501]

Can we built these in large scale?? For vessels

[@litoly3216]

Nice model 3 in the garage

[@adamsmith2719]

"Predictions are difficult, particularly those about the future" :-) Aside from the fact predictions cannot be definitive statements, it is simply more prudent (and practical) to say something "as of now" etc. So yes, LiIon batteries are main type today and in the near future but not in the future in general, as pointed by many in the comments. Just saying...

[@aminokamad1681]

Awesome 2021

[@icee4913]

3:15 Can you explain what factors cause the drop in cost/kWh?

[@ZackWolfMusic]

Flip of the switch from the elites is what causes deop in kilo wats

[@mmathes4704]

It's still a somewhat new technology when you consider how much research has been done so far. As it's rise in importance was't really predicted nor predictable. That's why big increases in efficiency are still achieved.

[@Randomguy-wd5lw]

Economy of scale for the most part i think, all the smartphone, tablet, lap top created demand in 2010s which increased production, by increasing production there is economy of scale, each battery are created more efficiently and with less labors.

[@rashidak7821]

Good sir

[@raghunathsinghrajpurohith4894]

[@BranFlakesR1337]

so will Li Ion batteries last longer if you keep them charged longer than you keep them depleted?

Maybe you can add the environmental impact of this batteries as well

Modern laptop batteries can last more than 3 years.

[@Baigle1]

old ones lasted 10 years if you took care of them

[@devilsoffspring5519]

@@Baigle1 The old ones were nickel-based, so they lasted longer without much care. But, they stored very little energy for their size, so were not suitable for modern electronic devices.
