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.
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.
@@Styrofo4m graphene has more mah on a smaller footprint. means lighter and longer lasting and compact. what is the prob of lithium elektric cars are to heavy and dont charge fast enough. graphene charges way faster
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 :)
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?
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.
@@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.
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.
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.
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
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.
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.
"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...
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!
And the big problem is that we will (except of the carbon) run out of rare earth metals . . . Also the production of those batteries is really damaging to the nature. My opinion is that batteries in this form won’t be the future, we need something else that doesn’t rely on rare earth metal. I think hydrogen fuel cells or something like this will be the future or in other words we have to switch to those alternatives if we want to stop the climate change.
6:26 What happens when the electrolyte is completely consumed by the electrons, will the battery explode or swell up due to short circuit? It'll be scary when the battery explodes by itself sitting on a shelf.
it will probably short itself (as said) but because the process is so slow it wont short with an internal current of over lets say 7 amps so the battery wont catch fire. Ones the battery is fully discharged the inside of the battery is in a stable condition so there is no voltage.
Unless someone finds a way to mass produce graphene, then graphene supercapacitors will be a thing, imagine phones that can charge in seconds and electric cars that can charge in mere minutes what a future we have coming.
How can you say that battery operating costs are lower? Where do you think the electronic to charge these batteries comes from & did you include that in the cost? Plus the lost of energy in generating, transporting, & store this energy... all of these are hidden costs.
May be dangerous and crazy, but I just rejuvenate many 18650 cells from dead laptop with this simple method; Zap the cell with very high voltage with low current in pwm mode. I just use 500V 1mA-10mA to cell with 1KHz 50% duty cycle for 1 minute, check the voltage of battery, repeat if needed until the battery reach 2.5V or more and can holding this voltage for 5 hours. Then charge it with proper charger until full. May be the capacity not recovered to original, but it be usable for some applications. E.g, dead Panasonic NCR18650 2600mAh rejuvenated to 2200mAh with many times in zap mode. And now became a part of my ling life Head Torch for camping, very usable battery; back to life from trash.

Are you ready to support Learn Engineering today? www.patreon.com/LearnEngineering . We will be truly thankful :)
This is can reduce pollution in the future
Sir can explain with animation how electric locomotive works because there is not any source I found to understand...
People said Li-po is safer?
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.
good for you man
Can these batteries be recycled? Would love to see a video about that process
i hope one day the batteries can be recycled safely that's probably the other part of making the batteries last longer

Argentina Bolivia Chile: Has Lithium
USA: Democracy much?
Thankyou Dr. Yoshino Akira
Future !! 😕
It's present...
Future is solid state and Graphene batteries...
Jonny Hindu Ikr
Or how about Sodium-ion battery?
@@Styrofo4m Yes, so 1999. You can find solid state batteries everywhere in 2019. Oh wait.
@@Styrofo4m graphene has more mah on a smaller footprint. means lighter and longer lasting and compact. what is the prob of lithium elektric cars are to heavy and dont charge fast enough. graphene charges way faster
@@TheFourthWinchester thats why 2020 flagship phones will all be using graphene :p
Explanation was so good, lucid, simplified and palatable to engulf easily with enormous information.
Please make a video describing
"How does a lithium air battery work".
They too behold the future like the lithium ion battery.
0:30 she has definitely gone OTT with the implants
*Future Technology.
It's the silicone expansion explained at 4:05
some women have breasts like that but they are so rare that it's a high chance that a woman like that has silicone injection rathar than natural :)
What do u expect? The video was made by a man.
I had to cover her with my hands because all I could hear was "titties titties tittis and boobs boobs" when he was talking
Wow, you guys are on fire with the uploads. Everytime I see a new Learn Engineering video I get excited!
0:21 Poor man, he got his am broken. :DDD
Oof
😂😂
What's that pause at 4:07 LOL
Perfect vídeo as always
Thank you so much!!!!!
Nice video bro you channel is best channel in technical explain.
Your explanation is better than others....
Thank u for all the effort making such a great video

thanks for you that let me get more knowledge of lithium ion ，but some phrase still don't reveal
You guys have really come a long way. Great video. Next time more info on the LiAir battery please
The liar battery !?!?!? 😂😂😂😂😂😂😂😂😂
Most complete comparison and explanation I have seen about this topic, great video
GOOD ANIMATION AND GOOD ENGINEERING
It is incredible how batteries moves many things on earth!
Thanks for explanation, the future is certain for a lott of technological devices with those battery's
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.
The animation is the best thing in these videos
Great video, thanks! You mentioned 3 important characteristics of batteries but isn't there are fourth one- charging time?
Modern laptop batteries can last more than 3 years.
old ones lasted 10 years if you took care of them
@@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.
Mine lasted 5 year
watching this way makes it lots easier thankyouoz
What about the super-capacitor.
Why not we considering it for the future?
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.
What about the potential of supercapacitors, which are currently only in their infancy stage of development?

Post more of these please!!!!!!!!!!
3:15 Can you explain what factors cause the drop in cost/kWh?
Flip of the switch from the elites is what causes deop in kilo wats

Great to listen. OSM even lectures can't explain like this . Good teacher. Covers #all subjects so I love le. Tq
I really like your videos. what software do you make in this video?
solid state batteries are the future
Hello from Bangalore...
Who designed logo it's fabulous.
Interesting video as batteries of the future
Hello and what is your opinion with carbon acumulators?
Awesome video thanks for the quick learning
"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.

Please upload videos regarding signal capturing and signal encoding
Which software do you use for animation?
blender
I think this should have stated sponsor of Telsla with such a large amount of brand advertising.
So if we leave our laptops on the charger it should longer battery's lifespan then previously predicted?
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?

Thanks!
You really love that smiley I think
Well, it's given us a clear understanding that whoever made this video has a vested interest in Lithium-ion batteries anyway.
A battery is also a possibilty out off plastic with a wax-coat which has a positive charge
wtf man
I love the angry, bitey electrons
They are ANTIFA electrons.
SEI layer be like “You either die a hero or you live long enough to see yourself become the villain.” 😄
Always interesting to watch this videos!
Nice explain! Thanks
Replace the 5% silicon with 5% ethanol👍
how about lifepo4 ???
And the big problem is that we will (except of the carbon) run out of rare earth metals . . . Also the production of those batteries is really damaging to the nature. My opinion is that batteries in this form won’t be the future, we need something else that doesn’t rely on rare earth metal.

Sounds like a Biden worshiper.
Lol
What about Vanadium batteries? I've heard they have some advantages over Lithium batteries.
Vanadium is highly toxic and as far as I know not that common, so it's unfit for widespread use.
Can we built these in large scale?? For vessels
Thank You
What about NiCd batteries?
Why wouldn't the Lithium Ions react with the water in the aqueous solution meationed at 8:30?
I always wanted a Chemistry Teacher🙂
Like you in My School day's ✌️😉💐
Nice model 3 in the garage
Always interesting and informative videos
Informative
Thank you Sir
Maybe you can add the environmental impact of this batteries as well
thx for this informative video... and, Katrisha is gorgeous in red...
TNX!
Thanks to CURT🤟
Good sir

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.
Please make a video on how folding display work
Thank you too.
Sorry, Do you have PDF file of this Video. Thank you.!
I never knew PacMan had such rich lore.
Now I’m scared of electrons...
You wouldn't be conscious without them, so don't worry about it too much
Tell us working of Wi-Fi and bluetooth.
Harshith Prasad why dose he know so much knowledges ?
I can't believe you didn't mention SSBs!!
Can you realise a video about auto-reload tires that works with friction ???
Amazing
18650s selvaged from a 2006 laptop battery pack are still functional and holding charges. I use them in a DIY power bank case
Got a physics test tomorrow pray for me 🙏
#PRAYFORISKANDAR_SAHIH
I'll think for you, don't worry!
Instead of wasting your time praying, try spending it studying
Finally
So nice
Understood that it is the future but not the present, but still some corporate cartels are trying to shovel it down the consumers throat.
so will Li Ion batteries last longer if you keep them charged longer than you keep them depleted?
Thanks about the tesla company,and to M.r Elon musk,and all of the team in Tesla company
How can you say that battery operating costs are lower? Where do you think the electronic to charge these batteries comes from & did you include that in the cost? Plus the lost of energy in generating, transporting, & store this energy... all of these are hidden costs.
how do hydrogen fuel cells work and is there any potential in H2 tech?
awesome
I'm confused. Last 20 seconds, they suddenly mention Li-Air has the potential to be so much better. So if anything, isn't that the future??
May be dangerous and crazy, but I just rejuvenate many 18650 cells from dead laptop with this simple method;
Zap the cell with very high voltage with low current in pwm mode.
I just use 500V 1mA-10mA to cell with 1KHz 50% duty cycle for 1 minute, check the voltage of battery, repeat if needed until the battery reach 2.5V or more and can holding this voltage for 5 hours. Then charge it with proper charger until full.
May be the capacity not recovered to original, but it be usable for some applications.
E.g, dead Panasonic NCR18650 2600mAh rejuvenated to 2200mAh with many times in zap mode. And now became a part of my ling life Head Torch for camping, very usable battery; back to life from trash.
