Extra points for making emergency solution in actual emergency ;)
Nice demo again...very clear, thank you. Have you considered soaking the AC and separator in fully saturated electrolyte and allowing them to dehydrate, then wrapping with the foil anode and storing as a completely dry & inactive cell ? Then, when an emergency hits, one could simply hydrate the cell by immersing or soaking in water and you have instant emergency power.
Really good idea,.... need to try. I was thinking almost in the same way,.... but I was thinking of just puting some pure salt to the bottom of the cell, and then just ading water and mix. But that idea can be used when you have cell housin like was in the video where I make reusable aluminium air battery.
Bravo😃 Preparation is the answer.
What I have done is save all my used dry cells. They still have useable power. Then I built a special circuit that will work on very little power to light an LED. It will light continuous for 60 hours or will flash brightly for over two years on one new AA cell. I figure I have over 20 years of batteries for this light. On my yt
Awsome
Thanks so simple and available . Will recommend to all my friends.
Nice, easy, efficient, useful. Phones charged. Several more of these, fatter, and heavy duty car batteries charged overnight ready for microwave oven duty, washing machine or TV. Dads all over the world, take heed.
it's just a super simple battery. I'm glad you share your updates. you checked it for the time of work. How fast does aluminum corrode? how long can she work? there is a dependence on the current consumption of the operating time?
That was the point to make simple battery. The battery work first for 20 hours and the aluminium foil was almost all corrodet and the cell was also almost dry. Then I add fresh electrolyte and aluminium,.... and the battery works for another 24 hours or better to say,.... it still works (but this time the aluminium is still in good shape after so many hours).
I'm really glad you're pursuing this. RMS really disappointed a lot of us by abandoning his battery project.
WONDERFUL ALWAYS LOVE YOUR TEACHING 👍👍👍THANK YOU
I've been interested in Aluminum batteries for a long time. However, I wanted to know if you know a simple way of recycling the used material back into aluminum.
You can easily but you need a lot of energy
Hi I've been all through your channel and you've done a jam up job on the battery and fuel stuff.
Thank you so much
They've been calling for rain for three days where I live and not drop! My permaculture garden could use a little, your getting too much, im not getting enough!..also started designing the supercapacitor to laser scribe for the low cost off grid power storage system. I mixed school glue with table suger to carbon load it then I'll hit it with the laser to carbonize it...adding the sugar should make a much larger surface area graphene carbon that can be placed on aluminum foil. Wanted to try the pla battery you made first as I have already printed up the housings to test it. I may need to make a graphene conductive ink using pva and add sugar. This way there's no need for the carbon felt. The graphene and sugar once hit with the laser should expand like if you added sulfuric acid to make a high surface area graphene sugar snake...I hope.
The best! 👍👍👍
what if you build that cell on 1/4" or 1/2" aluminum plate instead of foil? might have less surface area but should last longer.
Battery building by candle light! How romantic! Lol.
Hahahaha
is it rechargeable? or is the aluminum consumed in a oxidative process?
The second one, yes
Better use Washing Soda or Pottassium Carbonate. You will get about 1.3 to 1.4 Volts per cell and the Aluminium foil will not dissolve so fast !!!
Reduction Oxidation.
I imagine the more it dissolves the more power you get. Is that true?
Give a try to baking soda and some thin lead sheet or roll electrodes.
Charge and discharge it many times. reversing the polarity occasionally. and the capacity will grow more and more!.
Works and rechargeable! Very high discharge current as well if you make the design with thin separator and spiral wound roll sheet or lots of thin flat parallel sheets stacked.
You can use as thin as 0.3mm lead sheets and it works!
Thinner lead sheets you can get more capacity and power in the same size but lower lifespan (cycles)
Thicker lead will take up more space but will last a very long time.
You can even use soldering wire if it contains enough lead. wrap a few layers of napkins around it then wind on another layer of soldering wire.
You can use a pencil or small plastic rod or a pill bottle to wrap the wire around. Make sure the separator is thick enough to prevent short circuits.
Electrolyte of baking soda is very safe and ive not had much trouble with it.
The voltage fully charged is roughly 1.2-1.5v
Discharge voltage is around 0.9-1.3v similar to an AA battery
You can use several in series to make a pretty simple and decent rechargeable battery.
When doing the final charge cycle you'll want to stick to the same polarity from then on. and charge it for a long time at trickle charge. low current. 10-25mA to about 2.4-2.5v
That will decrease the self-discharge rate.
The longer you hold trickle charge on it the lower the self discharge.
this "brown thing" on aluminium catches fire? what is this?
Nice place you life, if there is no storm. Brilliant idea, could you prepare a cell and add the electrolyte when you need it?
Yes
You can take the outer skin and corroded zinc off a zinc cell and put a napkin around it and wrap in a few layers of foil and use koh or washing soda for electrolyte . Its fun way to use old battery and also use joule theif circuit to light led easy.
A zinc aluminum battery? = 0.9 volts
Wow i love the storms❤
🤔🤨😁
It's a carbon and cement super capacitor.
What is the formula for the KOH solution?
For 1 mole solution? Is 56g KOH in 1 liter of water,.... or 5.6 grams in 100ml of water.
does vinegar activate carbon, it conducts current better in vinegar as the solution
have you tried ethanol + koh as the electrolyte
I mean 100% ethanol + koh, no water
fatty acids in ethanol-koh solution? lol, I mean ethyl esters, synthesized
aluminium with koh generates a ton of hydrogen tho
something better for aluminium
The KOH POWDER IS POTASH DRAIN CLEANER
Use white LED.... it is better.
Yes, but I have this 1W led only in red.
I think that your battery will turn better if oxygen can touch carbon electrode
Correct. The cells are not airtight so the cathode can breathe.
If you made 5 cells could it power a mobile phone. That would be quite useful.
Yes you can
It may produce the voltage but maybe not the current under load. An LED works on as little as 20 milliamps. Cellphones take considerably more current.
@@justtinkering6713 This led is 1W led
@@justtinkering6713 would it work if you connected 5 cells in series to get your voltage then add more sets of 5 cells in parallel until you got enough power to charge a phone. (in an emergency it might be worth it)
@@cayrex I use a 1 watt, white led for my long duration led circuit. But I think the red is better during an emergency because it doesn't ruin your night vision. When a white led goes out during an emergency, it takes time for your eyes adjust to the dark. Red light doesn't have that problem . Great battery.

How about lighting a white 1 Watt LED with 3 or more cells ??
Here I light up with 1W red LED.
