#S2T#ScienceThursday#AluminiumAirBattery
@S2T, excellent presentation. You focused on the MOST important issue of Aluminum/air batteries: The "recharging" issue.
It's really unfortunate.
Yes people focus on range without thinking of the fact that this is a use and throw system
This was very helpful, thank you for posting it!
I am glad u liked it
good to see something other than fanboying about these batteries
that is why I am here
I was able to follow you alot better by setting the video speed back to .75
Camera recording limit
Thank you so much for this! I'm now a new subscriber. Was looking for environmental power for things such as sailplanes, electrolysis rebreather, and e-scooters, etc. But, I'm very cautious of the impact of my actions.
Western capitalists will probably take full advantage of this to make 4th gen jump starters, new consumable batteries, and other things to get rich while the world suffers. I don't understand why we have a majority of consumable batteries still. We have to change before the world can change. Many have lost focus from toxins and E-waste due to climate change.
Thanks again for the info! Love the Fake NEWS titled slide. I suggest going with better contrasting color schemes though.
👍👍
The same western capitalists that invented the computer and software your watching this video on?
Those darn USA people researching and developing technologies for a better future? Developing the COVID vaccine too?
I mean they are so high on the list for world polluters, like 87 I think?

Get off the Kool-Aid man. Capitalism isn't perfect, but is for damn sure better than what the rest of the world has to offer. We have non-rechargeable batteries still because people are lazy. Those damn capitalists have invented rechargeable batteries that are on the market today and the price is competitive with just a few charges. I know, because I use them. So don't go blaming capitalism.
Oh and BTW, there is a fundamental flaw with this concept in that you first you have to mine the aluminum. Sure we have a bunch laying around now, but it isn't suitable for a long term global solution. We are better off with hydrogen, ammonium, methanol, or a newer battery. You want to help the world? Figure out how to bring the top 10 polluting countries out of the dark ages so they can afford catalytic converters on their cars. That will do a lot more for the environment then blaming the people that make this world better for all.
Please note that the preparation of aluminium from bauxite involves a very large amount of electricity. When you burn or oxidise it electrochemically you are merely releasing that energy again. In fact, due to thermodynamics, you will get LESS than you put in. That is always the way. In effect you are using aluminium as an energy storage medium. I'm not saying that it makes no sense, but be aware that you are not getting something for nothing.
I say the same thing in my video its not an energy source its a energy carrier
The energy to recycle aluminum is roughly 1/6 of the energy needed to process aluminum from bauxite ore. Once mined aluminum is refined from its ore it is cheaper and more energy efficient to recycle the metal, so the cost of aluminum-air batteries are not as expensive as many would think.
Thanks S2T, very informative and well presented. I dont mind replacing whole battery or swap with new one; Indian oil thinks they can establish operations to swap battery with in 3 mins. I think there are many applications for these batteries in rural india, including delivery service (like fuel delivery service by Booster in San Jose). Chinese company offers li-ion battery swapping today in China. Bigger Question is what is the cost to recycle used battery, i am hearing 1/8th cost compre to producing aluminium from ore? There is a recycle market for aluminium, including soda cans, today, and there will be a recycle market for aluminum batterries. Ant not to mention there is abundance of aluminum in India and other parts of the world.
bro where will u get the energy to fuel the waste its only 20% efficient that is the problem to power 1kw u need to make 5kw that is the main reason oil company is making it for mobile tower gen set where it will work everywhere else it will cause so much waste and pollution u would be better of just using fuel
Pretty good presentation, but I’m having issues with some of your final conclusions.
1. You know what else “changes the format” besides aluminum in aluminum air batteries? Petrol and diesel. Combustion engines aren’t inefficient because the change from a chemical into energy is inefficient - they’re inefficient because the energy is lost in the TRANSFERRING of that energy to the components that push the vehicle forward. That has entirely to do with an internal combustion engine vehicle design, not anything to do with the “change of format,” or the change of state from the fuel into energy.
Where did this 20% efficiency number come from?
2. Yes, current EVs are 80% efficient in the transfer of power from the battery into propelling the vehicle forward. Aluminum air batteries would be exactly the same because they are also batteries propelling the EV forward.
If you think aluminum air batteries are only 20% efficient, where do you think the other 80% of the energy is going? Do these batteries get super hot? Do they light up or make sounds? Where is this missing energy at?
3. The cost of recycling varies tremendously. If I had to built my own furnace at home and attempt to convert aluminum oxide back into aluminum, it would be prohibitively expensive. It would be much cheaper for an industrial smelter to recycle aluminum oxide en masse, however. The energy to operate the smelter could theoretically be powered by renewables or nuclear.
20% is the power that will take from the grid as in kwh taken will go to the battery & remaining 80% will be waste heat in recycling phaser which some people mistakenly think is recharging
@@s2tenglish I think this is the only real problem with your presentation. The way you’re presenting the energy loss scenario, you’re basically making the argument that these batteries ARE rechargeable, because you’re saying that they get “recharged” in this very specific (and expensive) way.
A better way of saying it is that these batteries are consumables (like gas or diesel) which can be recycled afterwards. The primary benefit over gas and diesel being that they burn more efficiently and produce fewer atmospheric toxins.
As for the efficiency number you came up with, I’m still skeptical. Say I recycle 1kg of aluminum oxide and it loses 80% of the energy to waste heat that the aluminum produced as a battery. The next time, I recycle 2kg of aluminum oxide in the same manner and it produces the same amount of waste heat. Suddenly the heat waste to potential energy ratio is 2:5 rather than 4:5. (That is, 40% waste heat rather than 80%.)
A better analysis than “waste heat” would be analyzing the amount of atomic energy needed to transform aluminum oxide into aluminum and vice versa. The waste heat varies entirely depending on the efficiency of your recycling methods.
Really clear presentation. The amount of energy required to recycle is eye opening. Too bad. Initially it sounded so hopeful.
old saying of if it's too good to be true it probably is
Very informative. So simply explained. Bro u have fantastic skills
Thanks
I am a retired Prof in phys chem and chem eng permanently living in Malaysia since 1995. Please give me a link to discuss some ideas in my mind on how to make Al-Air FC practical in SEA settings.
I am just an artist man
Hello Mr Vladimir- I am interested to explore opportunities mass manufacture Al-Air batteries. please pm me if you are intetested and available. I am located in San Jose, CA.
Very insightful, thanks for doing this video.
Glad it was helpful!
Greate sir ...subscribed
Thanks and welcome
Empty propane tanks are usually exchanged for a full tank. In theory an aluminum battery exchange does not sound difficult to do. Question is can a manufacture rebuild recycled batteries with new aluminum cheap enough for the consumer to take interest.
But a trade in propane tank is likely to be used for cooking, which is not as scary as if a trade in battery leaves you stranded as you try to get the last bit of energy out. But This risk could be mitigated by pairing with a rechargeable battery and electronics that switch you from your aluminum air battery to your rechargeable reserve untill you can get your aluminum air battery replaced.
U missed the point can it be done YES should it done NO . why not as its too goddamn inefficient
@@s2tenglish I really did catch all the points you made, but i have a different take on why it should or shouldn't be used. In the end, what matters is "is it cost effective" and that was not made clear in this video.
Home rechargeable or not is not a game changer or show stoper. But cost is. The other issues can be worked out, worked around and such, but if cost can't be worked out, then it's a no go from the start.
While Efficiency is nice as it's a means to an end (generally resulting in reduction in cost), efficency means nothing if 100% efficency requires unobtainium with a much higher cost. Lastly, how ok are you with child slave labor being used to get some of the materials used in lithium batteries?
dude cost effective means "efficient". If u are wasting 80% of energy who will pay for it ??? lets say your truck fleet needs 10 MWh for 1 month u will need to pay for 50MWh every time u cycle those battery that is why It cant be used where its a main driver u will go bankrupt with bill itself . how ok are you with child slave that is a mute point, as iPhone as use it and so does majority of goods made in china and it will auto solve after a while as we move to more and more automation even in mining and if elon musk build mining system in USA as planned that wont be an issue
Nice video doing research for school
Good luck
V Good Presentation but I missed one issue : Are there Aluminum Rechargeable Batteries research going on to develope? Thnx for posting
Not that I know of don't even think it can be done in room temp
Sow spraying micro particles of aluminum into the atmosphere, the waters would dissolve the aluminum into white skies .
? only the outer layer of particles will bond with oxygen
Good info...appreciate if you talked a little slower.
Sorry about that
you can slow the video speed down, click on the gear
Bro I thought there was something on my phone lol
Wow
Great Video
Glad you enjoyed it
Just curious, how many kWh does it take to produce one kWh of Al-air battery (considering that producing aluminum is SO energy intensive, about 10-15 kWh per kg, if I remember correctly) ?
as there is no off the shelf component its hard to tell
I charge my puppy when it pees on a ground faulting light pole
LOL
I've seen what I believe is an aluminum air battery using a D.E.C as the electrolyte working as a secondary cell. It contained no water so would it be an aluminium ion battery?
I think so
I can understand everything you say and it was well presented. However, *slow down* the presentation speed about 20%. You sound like you’v had a few too many espressos just beforehand. 😉
Sorry about that but that is because of my cameras recording limit
Someone is going to suggest putting Hyrogen Peroxide in the battery to supercharge it.
I am hearing it for the first time
the whole damn battery... awh he'll nah
The devil is in the detail
Myth buster 👍
Enjoy
How does this compare to a hydrogen fuel cell?
both are bad for mass production
I know this is normal conversation pace for you but I suggest you make an effort to SLOW DOWN your presentation.
I am sorry this is due to my camera recording limit . U can slow the video to your liking
I don't want to be that guy but I'm having a hell of a time understanding the accent. You speak very well but your excitement and accent together makes it hard to understand. If you'd slow down a little it would be so much easier to follow.
sorry U can slow down the video to your liking my issue is camera recording limit
@@s2tenglish How about that, first time I knew that you could slow the video down on UTUBE, now I can understand the speech etc.
Maybe if you spoke even faster we couldn't understand ANYTHING you said.
U do know people have different speaking speed that is why CZcams provides playback speed control
Flat out
odd !
Your exposé is very good, but you speak too fast and because of your Indian accent it’s hard to understand you !
Sorry
1 sal ho gya ayi ki nahi battery lagta hai
Pheku hai bjp it cell
what ?
Slow down!!!!
U can slow down the video to your liking I am limited by my cameras record limit
