How great you are!. You are absolutely right. To get what we want, we should do experiments continually repeating failures. And those failures lead us to think more and more about the outcomes, thereby leading us to arrive at better places.
That is excellent, I will try that on the aluminum that I put in my Cement batteries. I had over 4 years of use with them but the current got smaller of time. This method could allow the current to stay higher longer. We shall see. Thank you for your research.
This experiment was interesting! Using zinc oxide to plate aluminum, this battery was more like zinc-air. Rechargeable metal-air batteries use catalysts in black carbon to make the oxygen reaction reversible. Maybe you could be try this and verify the ciclability
By the way, using KOH as an electrolyte doesn't seem to be desirable. Roughly saying, it will produce Zno and H2O, which means the battery you are developing might not be desirable. Good Luck.
AH!!! I perfectly agree with you "To find something, we should do experiments!"
Good Luck to you again.
Helo my friend. I think that, this battery is zinc air, with aluminium collector. Am i right?
Yes. More or less. The zinc oxide is mostly used in some new aluminium air batteries,... but in small quantities.
Thank YOU.
And
Good.luck.
Oh god that beeping noise in the background makes me crazy 🥺
I feel you 😨😱 is a gas alarm, because the gas for heating is disconnect and the conntrol of the pump see this like error.
Would you try a silicone oil mixed with an electrolyte, would that make the battery last longer before ultimate failure as and aluminum air battery
Maybe, I dont know 100%
Check crystal battery , those don't need to be charged and they put out power continuesly. Less dense but all you need is add water every few weeks.
Logical experiment after your previous vid, good work.
I think you would get more information using your electronic load to measure charge / discharge graphs.
What did the negative electrode look like after a few cycles, was it holding up?
I hope it was one of the 5 useful experiments out of 100 :-) Martin.
later I was using the electronic load. The battery last around 12 cycles. After 12 cycles the capacity drops. So, no to this one, but it was a good experiment. The negative electrode looks good,... and was like by start,... zinc plated on aluminium with no visible degradation.
maybe if I add some NiO or MnO2 to see what will happen this time. Because of the zinc, the battery will act like MnO2 - Zn battery?
@@cayrex The fact that the Al did not corrode and the Zn plating remained intact is very encouraging.
A Zn plating on Al foil current collector would be very desirable in a Zn chemistry battery, very cheap and plentiful.
It maybe worth replacing the AC side of the cell and trying again, see if you can get another 12 cycles, it would show the problem was in the cathode side of the cell, and prove there is hope for further experiments using the anode.
@@cayrex Yes the MnO2 would be a good idea, maybe working like Zn - ion cell :-)
Pretty cool effort.
The aluminum is the power source to convert ZnO into Zn. The Zn in turn is used for zinc air battery. It's electroless. No power needed. I will try 5 parts Zno to 1 part aluminum and see if it converts all of the ZnO into zinc metal powder using NaOH. No worry about aluminum corrosion. It'll be totally consumed with lots of heat and gas. Capture it for fuel cell or vent it. The aluminum serves only to convert the zinc oxide into something usable for a battery cell. The power supply isn't used. The aluminum recharges it and acts as a sort of a generator.
Aluminium is stating to consume when all zinc is oxidized again during the discharging.
@@cayrex Add more aluminum with fresh alkaline and see if it regenerates. I believe it does. But the spent aluminum oxide remains increasing weight.
So technically air batteries can be recharged with only the oxygen present in the electrolyte? You don't need air from the outside? Because here there's no opening on the "air" side
Technical,... yes the oxygen from electrolyte additive can work,.... technical. Yes, you need air (oxygen) from outside,... If technical the battery will work on oxygen from electrolyte,... the oxygen will be limited. The battery is not vacuum sealed so the oxygen can go into the cell anyway.
How to increase the voltage capacity while designing itself is that possible by anyway
Love you man! Legend.
I really like watching this video.
I found your channel recently and I have been really enjoying your very informative videos on Solid State batteries. It appears your are the only one doing some really deep experiments on that. Thanks!
@@wwabete2009
Thank you
Hey there buddy . If you can work out how to plate magnesium into stainless steel then I think that would make a good battery that’s rechargeable by replaying the stainless steel and reinserting like like it’s a cartridge .
Nice idea,... but this will not work! You can not plated magnesium aqueous solution material.
cayrex2 is there any way magnesium can be plated to stainless ?
@@Buzzhumma The problem is that it just can't be done. All of the electricity you put in will go solely to converting water into hydrogen and oxygen because magnesium is so electrochemically active, that it fights reduction to metallic form more powerfully than the hydrogen. Maybe can be done with non aqueous solution. ChCl : urea : MgCl,... maybe.
Magnesium is so reactive that it is right to say that plating magnesium on aluminum is impossible.
The reason I say aluminum is because aluminum is a better material than stainless steel
What about a magnesium alloy that’s less reactive but still have hi energy of magnesium
So that's all it takes to make it rechargeable! ? That won't work for saltwater electrolyte though will it? Thanks man, you have some great videos.
Sorry no,... this works only in alkaline environment. With this I dont get many cycles,.... maybe will be better if I use a MnO2 or NiO
Hi Cayrex2
Very Very nice Presentation I give it a 10+
When you started the Battery the first time How long did it Run?
The the second time you charged it, How long did it Run?
And the third time you charged it, How long did it run?
I hope I hear from you Soon
Thank you Very Much. I subscribed to your channel..... VERY INTERESTING
I dont remember the runing time of the battery,.... but it last 12 cycles before the cell capacity reach 80%
@@cayrex Hi So you mean you charged it 12X to get 80 % capacity right?
@@mjmurawski yes,... affter 12 cycles the capacity drop for 20%.
Like
ty for the experiment
what power supply are u using ?
No problem.
@@Fortitudoo BT 305 from Basetech
@@cayrex ty i got the load tester u recommend while back and that works good
To try and reduce aluminum break down use gum arabic mixed with electrolyte. Seems to work.
Hmmm,.... interesting idea

Senegal will love us for this.
It might be good if you told us what the electrolyte was
It might be good if you see the video its all in the video. Oh, you have two videos about electrolyte to be more exactly
👍
Make ur video short and sweet and to the point, don't beat around the bush. Also do your homework first before doing publishing ur video on youtube.
But I like the bush! homework?
Who pays you ,my friend? :)))
