I loved how excited he got when the battery worked, we need more of that genuine excitement for science and expérimentation 🎉
Your work was great, we are waiting for the next video🇮🇷🇮🇳
Good progress man keep up the great work
nice electricity project, really interesting
Thanks bro for showing a working air battery
Very interesting looking forward to more exploration on this battery
that is galvanized steel, (then it will be a zinc-air battery) aluminium looks like the heatsinks on your LEDs, aluminium air gives out about 2 volts per cell, and tends to fall quickly as hidroxides block the cell.
its certainly Zn galvanized steel, and I guess that battery lasted for 20 minutes. its like 12um Zn max on it, and it goes so fast
Nice to see you all participating.
The anode metal i used is aluminum. It looks like that because i started working on air batteries around 3 months back, and that's when i poured Koh on it because of which it lost its shine.
Yes, i also tried aluminum heat sinks as the electrodes, and i got the same result as I am showing here. Same for the aluminum line cables as electrodes.
For me, Vmax was 1.7v per cell in one of my experiments under some very specific conditions. It's not shown in the video.
no, it's aluminium but that is not an aluminium-air battery but a voltaic pile. The aluminium has about -1.7V electrochemical potential and the carbon is just an hydrogen electrode which has a potential around -200mV because the electrolyte is alkaline so, the open circuit potential is about 1.5V. The indian knows nothing about electrochemistry.
Very good job guys, I'm glad to see
Verry very cool brother xD keep the good work up, also my first time seeing u talk fr
how long this kind of battery will prodce current ?
Good job!
Very Nice. Thanks for sharing
Cảm ơn bạn đã chia se cho mình một video về cách chê tạo pin bằng than chi và nhôm rất hữu ích, chúc bạn vui ve hanh phúcva thành công trong cuộc sống của mình.
You are most welcome 😊
How strong is the solution of KOH?
Awesome!
👍verry good 👍thank's
Where do you get air battery if you use an electrolyte?
Is the plate of positive side copper plate ?
Please, reply to me
Nice video, keep it up, thanks :)
nice idea 👍
I made one of this as a kid without realizing that it was a new type. I soaked a piece of charcoal corn cob in salt water and wraooed it in aluminium foil, i was playing with it connecting it to a speaker and i loved how it made noise in the speaker. 😂😂
Quite possible. Good work 😀👍
@@MrElectron size of carbon brushes?
Is the best friend,,,thank you.
Sangat bagus sekali kawan 🙏👋
Wow...that was great 👏🏻👏🏻👏🏻👏🏻 congratulations on your initiative...I wish you a great evolution in the study of this battery 😊🙏
I think the purple one was Ultraviolet LED. The dimness is because most light produced is outside visible range. Be very careful with it and not shine it into your eyes for long!
Хорошая работа, продолжай в том же направлении. Желаю удачи. У меня одна ячейка запускает в пол накала лампочку на 2,5вольта без щелочи, на воде
Так алюминий не окисляется в обычной воде из-за пассивной плёнки 🙂
@@Michael-oq2wx это вы ещё не видели как алюминий прикрученный к железу на воздухе под дождями в труху разрушается
pero donde esta los nombre de los elemento que utilizo para saber excelente
good work
Interesting, homemade carbon battery
Nice work 👍
Thanks 👍
Great amazing
Nice 👌
You made a good DIY battery, I am confused as to how the carbon brushes are working as air cathode? Also it would be better if there was a non caustic electrolyte as we know much anode material is lost due to reacting and releasing H2.
Can you easily buy Koh powder in a tub in your local shop, we don't have it nearby? Thanks 👍
I'm no chemist but as I understand it, you'll have to mix the pot hydrochloride powder w distilled water which, after double checking my math, would make the hydroxide. Dunno if you can get it premixed. I do know someone who's in the know, tho. Starts w an A & ends w a zon. Tell em Troy sent ya. 😁
Thanks! Video about the same is coming tomorrow or the day after. Yes its easy to buy koh here.
what other electrolyte solution can i use to get a similar voltage an performance?
Coming very soon with everything in full detail. Probably this week.
Very good, how long did the charge last feeding the leds?
Upcoming
VERY COOL, DO YOU KNOW WHAT KIND OF GAS THAT THE ALUINIUM GIVES OFF
AS IT IT CONSUMED ?
Hydrogen
This battery will need to charge also when it's lobat
Is it rechargeable?
what laquid when you drilling hole?
Nice
Nice ! Mais cela dure combient de temps s'il vous plait ? Merci
Video is coming soon.
Thanks for sharing for your bright idea about cell battery and we are been interested and padticipate as in commenting,..in my comment why you called it air battery? and my thought you make 1 cell that produce an output of 4.2 volts, thanks anyway and keep strive friend👍
Where does air enter the battery?
How many hours does it last?
Hi, very interesting experiment, how long does such a battery last? And are potassium hydroxide and caustic soda the same thing, called something different?
Thanks . No, potassium hydroxide is caustic potash
@@MrElectron Ok, thx pour votre réponse 👍
Brilliant and great perception, it will definitely bring a revolution in the industry and in the applications.All the best, wishes wishes wishes for
Thanks a lot 😃😊.
Donde puedo conseguir el idrosido de potasio y gracias por el video buen proyecto
I bought it online
Зола от костра имеет калий углекислый. Поташ. Для экспериментов этого хватит
The problem with this battery is the aluminium will be destroyed by the electrolyte very quickly no matter if you draw current or not. Probably you should remove the hydroxide electrolyte when the battery is in storage.
Ide yg pintar
What is the electrolyte used here , didn't mention
Its mentioned @4:42
Mantab
This is really great, aluminum-air batteries look incredibly promising, i appreciate you providing excellent information on it.
I have a question though, are the three carbon brushes per cell necessary? What would be the effect of less? Are you mostly just trying to get more surface area?
I can't want to test this chemistry myself, but i'm tinkering with zinc-iodine batteries right now, i dont want to get too far ahead of myself!
I'm glad you liked it! Yes, it's the surface area. All the best with your zinc iodine battery research. I, too, will look into them.
@@MrElectron thank you! I wish you the best as well! I was in a bit of a stall with my project, not knowing how to proceed, but you inspired me and gave me new ideas with your first Aluminum-Air testing cell.
Keep on tinkering! You're making the world a better place and I strive to do the same!
Thank you for these honorable words 😊😊😊.
Como criar os polos negativo e o polo positivo se os carvões são dos mesmos?. Essa eu não entendi 🤔
You have aluminum plates
What is the name of the liquid you added in it?
Koh aqueous solution
Distilled water boss
In case you're not chemically literate koh is potassium hydroxide. It's some pretty caustic stuff there be careful if you haven't dealt with it before.
Salt water
What is an acid forming chemical?
Как увидел с первых кадров шприц и электролит, так и понял -точно воздушная батарея.
can the battery recharged instead of add more electrolyte ?
It's even better. It can not recharge but needs only aluminum plate replacement. More details in the coming episode.
You haven't connected any load to measure the current 😅
Tưởng thế nào. Nửa thế kỷ trước người Việt Nam dùng "công nghễ này rất phổ biến ở miền Bắc. Nhôm làm điện cực là xác máy bay Mỹ.
Achava que o ensino medio era fraco somente no Brasil, mas quase 90% dos comentarios elegiando e surpresos pois nao viram isso na escola e nem sabem a diferença de pilha e bateria😢
सर इस बैटरी को कैसे चार्ज कर सकते हैं।
ma dov'è l'aria se serve acqua di mare o l'aggiunta di sali.. le bollicine dovute alla reazione chimica?!
Возможно есть материал или вещество которое может поглощать выделяемый газ еще до того как он поднимется на поверхность. Есть такое вещество? Например рядом с алюминием в электролит поместить его для частичного поглощения выделяемого газа. Ведь это касается безопасности, это важно.
Or one can find a method for reducing the hydrogen emission by modifying the electrolyte.
Yeah, my initial reaction was to laugh but, hell, you're on to something there!
@@MrElectron less h release would be Byproduct of lower output, would it not?
É o gás que reduz a capacidade da célula produzir intensidade. As bolhas ao formarem-se afastam o electrólito das paredes do eletrodo de alumínio reduzindo a superfície de contacto/ área activa.
Há substâncias que absorvem o hidrogénio. Nas pilhas zinco-carvão é o dióxido de manganês que é o despolarizador de forma a impedir que o hidrogénio isole o eléctrodo.
Aumentar a área dos eléctrodos aumenta a capacidade e a intensidade.
Если вместо раствора щелочи КОН использовать окислитель, например, хлорку, содержащую гипохлорит, то выделения водорода не будет происходить. Напряжение так же будет выше, примерно 2,2 В. Такие элементы используются в реальности. Для эффективной работы и большого выхода тока важна развитая поверхность алюминия и небольшое расстояние между электродами.
Не понял, батарея воздушная, с электролитом?
Can you tell how much current it produces??
I don't remember, but that part should be in this video or its third part.
please make videos on motor generators power station as u had done previously😢
Ok
what about using hydrogen peroxide instead of distilled water

😅
Would you possibly know how does Naoh compare to koh for electrolyte in these cells? I know it's simple enough to convert one to the other but just wondering for simplicity's sake. I can find Al and graphite on the streets picking up scrap all day and can buy a lb of Naoh at Wally world for ~6$ just koh is slightly less accessible
Btw meant to say ty for such a great concise video this would make a great cell for an emergency situation with the availability of these components. Keep up the good work.
Mah?
Great Invention
Is not an invention.
If excess heat from existing heat sources with excess can develope reduction of the aluminum
It's a great idea but, coming up with a battery that doesn't need replenishing/maintenance, or at least not for a long time would be the Holy Grail of batteries. Is that even possible?
А чем вас не устраивает этот? Всунули алюминий, вылили гидроксид алюминия. И так по кругу
"air" ? (since it uses potassium hydroxide for an electrolyte, it seems like an alklaline battery)
Que não é bateria, é pilha de Volta
👍
I think you should make another design where cathodes and anodes will be much closer
Ok
You might be gaining better electrical conductivity with using carbon brushed but your sacrificing surface area
How long will it last?
As long as the aluminium plate/ electrolyte.
Im gonna make one for my video is it ok
Sure
@Mr Electron thanks I appreciate you I'm making it next month
Wwoow,,so it worked without charging it??❤
Yes 😊
@@MrElectron thanks
Longtime ?
Why dont use another electrolyte type ? KOH is very reactive to aluminium, it will release h2 gas, as losses power..
Congrats
Modification of NiCD with hydroxid eletrolyl
Do everything the same. Use zincate for electrolyte. Amperage will increase with firm contact between anode and cathode with paper separator.Thanks
🎉🎉🎉🎉
Can u show the current.
Go to helk
Why more graphite than aluminum?
It gave better results in the past ( to some extent ) . Things are still under research.
El koh , hidroxido de potasio, me parece que tambien se encuentra en la soda caustica para limpieza de cobre ya que como es alcalino hace reaccion junto al agua.
Use large buckets, aluminium plates and charge you cell phone :D
No es una batería de aire, el electrónico es líquido. Disolucion de Hidróxido de Potásico...
NICE... IT IS POSSIBLE TO USE THIS BATTERY PRACTICALLY?
Yes, its going to hit the market soon.
Ez kamu!
This is very cool but I'm curious why you call it an air battery. It appears to be a wet cell like some of the earliest voltaic piles used in the 18th century.
Thanks ! It absorbs oxygen from the air for metal oxidation and releases electrons from the anode. That's why.
why is it called an "air" battery? I don't see any air in it. Is this rechargeable?
It's not rechargeable. Its a fuel cell. Oxygen gets absorbed from the air, hence the name.
dV must be under 1.2V to avoid elettrolisis
😮bueno derrazon el ensur está tan energético en el ser humano q sirve para prender LEDS doy a conectarme uno y les cuento 😂
Как можна называть электролитические батареи воздушными!??😮
АКБ на авто тоже воздушная?
This does not seem to be an Al Air battery, just a redox battery.
Lovely build brother, 1 question, won't the hydroxide environment eat up aluminium faster? Also at the end of cycle how much aluminium can be recovered from the oxides?❤ enjoyed the build
Yes it will eat up the aluminium but in the coming parts, i will share the remedy on how to avoid that. I still have to gather info on the recovery process.
@@MrElectron That's so great to hear from you, I wish we could connect, I build lithium batteries for multipurpose applications, I have been your suscriber for many years, enjoy your videos, Actually you can make a whole series of videos on aluminium air battery, using different electrolytes like, neutral, alkaline, hydroxide you already used, but even with hydroxides potassium hydroxide and sodium hydroxide both will have different voltages All the very best brother
