Using your electrolyte to turn you charcoal to a slurry is very much like what we do in lead acid batteries. The lead oxide is moistened into a paste using a solution of sulphuric acid, which is our electrolyte! You could take this a step further use stainless steel, or perhaps even aluminum mesh to press your charcoal paste into improving the plate conductivity!

That's very interesting. I didnt know that was how they that. Just a thought if I were to add a metal grid of some kind to the cathode would that not cause a side reaction with the carbon and electrolyte. I'm just thinking that because the anode is also a similar metal?

@SapioiT
@SapioiT 3 года назад
I think I see a posible improvement. The battery layers could act like the layers of a capacitor, allowing part of the current to go from the input to the output in more of a straight line, thanks to quantum physics making electrons jump from one layer to the next. You could still have half the layers having current going in one direction and the other half in the opposite direction, but have them stacked so the half going in one direction is below the half going in the other direction, and use a bit more aluminium and clingwrap to do the pairing of the sides. It could be a concentric U-shaped stacking, or sidewas-overlapping U-shaped stacking, depending on how you do the connection between each pair of layers. i.e. if the odd numbers represent current going in one direction and the even numbers prepresent current going the other direction, then the concentric stacking would be 13578642 or 75312468 (or mirrored, 24687531 or 86421357), and overlapping would be 13572468 or 75318642 (or mirrored 86427531 or 24681357). I hope that makes sense. It might not make a difference, my understanding might be incomplete, but I think it's worth testing, at least.

Hola, @Mechanic Gone Rogue !! Es genial. Y no lo digo por tu mejora, que por cierto, es muy buena, sino porque sos un verdadero investigador, y serio además... Seguramente te vas a dormir y seguís pensando en cómo mejorarla, jaja... También hago mis baterías, desde hace unos años. Prueba y error. Estoy tras baterias de electrolito seco y electrolito sólido, o ambas a la vez... Tengo baterías de arcilla con oxido de hierro mas sal comun. Y estoy dándole mucha atención al aluminio y carbón o grafito. Materiales cotidianos, y de bajo costo... Lo mejor es conseguir el máximo de diferencia de potencial entre metales... Ir probando con baterías de una celda y distintos electrolitos. Al igual que vos, aprendí que no hace falta bombardear los metales con tanta acidez, o mezclas que terminan anulando lo que buscamos... Y las estoy haciendo del tamaño de 1,5 cm3 o incluso más pequeñas!!). Papel de aluminio, grafito y el electrolito, miel de abejas (sí, funciona!!)... Es que la idea, es lograr que el electrolito se seque y, mejor aún, se cristalice. Ahí está la clave, creo. Cuidado cuando hay más de dos metales en contacto con el electrolito. Puede "contaminar" la prueba. Por ejemplo cuando utilizamos el cobre como cables o algunas mallas metálicas de niquel o cobre, como conductores, y los otros dos principales para lograr el voltaje... Es ir viendo para qué lado van las comerciales, e ir tras sus conceptos básicos... Leer sus "letras pequeñas", ver qué nos esconden para lograr el éxito. Mucha fuerza!!!

@___Chris___
@___Chris___ 3 года назад
Hi! I commented under your last video before watching this one. I see you already implemented some of the same things I suggested. Maybe you can build a third version that additionally also comes with a catalyst (such as mixing low micron titanium dioxide powder (or MnO2) into the graphite powder) and a reducing agent (/axioxidant) to reduce the amount of aluminum oxide build-up (such as e.g. ascorbic acid / vitamin C mixed into the electrolyte) and add some acetone to increase the solubilty of oxygen (or any other cheap gas solvent, if you can think of something better and less volatile). In case you have some epoxy and fiberglass lying around, you could also build more reusable cathodes: graphite powder + TiO2 (or MnO2) directly mixed with epoxy (--> the graphite in this solid sheet should also solve the conductivity problem), saturate the fiberglass layer with this mixture, then sprinkle it with dry graphite/TiO2 (/MnO2) powder before curing, in order to leave it with a rough surface after it's hardened. With a solid/non-permeable cathode, you would of course need air channels on the "electrolyte side" of the cathode. Two potentially stupid questions: 1. Do you think it's important that there is some kind of separator between "air side" and electrolyte or can oxygen be dissolved in the entire electrolyte (e.g. under pressure)? The reason why I'm asking: I know there are simple DIY "McGuyver" batteries made from an aluminum can, filled with salt water and with a central carbon or copper cathode. Of course this way only the top of the electrolyte liquid is exposed to the surrounding air (=with its partial O2 pressure), so not much oxygen will be dissolved, but it seems to work in principle, therefore: do we need an air cathode that doubles as a separator only to prevent leaking and in order to achieve a greater oxygen diffusion area or does the separation have an added purpose, i.e. would more oxygen in the solution (with diffusion to the anode) be a problem for some reason? 2. When several "cells" (anode/cathode pairs) are connected in series, can they share the same electrolyte or does it have to be physically separated between "cells"?
@MechanicGoneRogue
@MechanicGoneRogue 3 года назад
Hi there @ Christian S. Thank you so much for your brainstorming comments. Some of your suggestions involving titanium dioxide or magnesium dioxide have already been on my radar for a while. Only because others have commented in similar fashion. I appreciate this though, because it indicates to me there could be something there if so many people are talking about it. The use of acetone is new though. I had considered it's use for an organic non aqueous electrolyte, but didn't follow through because I felt that the solution would be too volatile. I didn't really consider that it would increase the solubility of oxygen. I might have to revisit that. An epoxy cathode could have potential as well. In answer to your questions. 1. As I understand it (I might be wrong on this) the oxygen is absorbed by the carbon source and transferred chemically to the aluminum via the electrolyte. I don't believe that the electrolyte itself absorbs any oxygen. As long as the air side is not prone to mixing with the electrolyte, I don’t think any kind of separator is necessary. In my designs the air side is always on top of the electrolyte. In the examples you cited. The Al/Cu is a galvanic cell so I don't think atmospheric oxygen is a factor in it's reaction, and as long as the two metals aren't physically touching they will produce a voltage. The use of carbon (I assume a graphite rod?) as the cathode in that design (where it is fully immersed in electrolyte) may be a different reaction. I say this because in my latest experiments I began using graphite sheet instead of activated charcoal and found it’s performance is not tied to exposure to oxygen. I’m wondering if it is functioning similar to a lithium-ion battery, but I don’t know how to prove it. At least for now. Nonetheless it is interesting. 2. I haven’t tried using the same electrolyte for all of the cells, but I would assume like other batteries that would not work. Probably a divider (like a car battery design) would have to be used between cells. Hopefully, that answers your questions. Thanks again for commenting. Cheers!

Great battery design! Do you know where oxydised aluminium ends up? In the electrolyte solution or on the surface on the aluminium sheet? I am wondering, if you had your aluminium sheets twice as thick, would you have twice the usable capacity? Also, if you are going to make more Al-air battery experiments with your current or future battery designs, I would like to see what happens when you let it discharge fully. How much capacity there is (at least approximately) and what it will look like inside once it's empty. Maybe also to see if you can swap out the aluminium sheet and use the battery again. Anyways, there aren't that many videos on RU-vid about Al-air batteries, and your videos are really great. Big thanks!
@MechanicGoneRogue
@MechanicGoneRogue 3 года назад
@Head Master Hey there. Thanks a ton for all this feedback. In answer to your questions. I believe the oxidized aluminum ends up in different places depending on the electrolyte (although I could be wrong). If it is acidic I think that it goes in the electrolyte, but for saltwater solutions I think it builds up on the anode. Thicker aluminum sheets could in theory increase the battery capacity, although there are greater problems hindering their longevity. The main one I see as electrolyte evaporation (mine only last about a day). I am working on more battery designs for future videos. Definitely will keep your suggestions in mind. I really like the idea of a post battery tear down. Thanks again, I am glad you appreciated my videos. I'll see you in the next one. Cheers!
@headmaster3300

@@MechanicGoneRogue Yes, I think you are right regarding where the oxidized aluminum ends up. It makes sense to me! I am looking forward to seeing your future designs. What if you would put your battery in pure oxygen?..
@MechanicGoneRogue
@MechanicGoneRogue 3 года назад
@Head Master I would imagine pure oxygen would boost the amp output, but I don't know by how much. I like your thinking though. I've toyed with the idea of using compressed air or pure oxygen for the cathode, but have not gone further with it right now. Something to explore in future videos though for sure.
@Faydali-Mikroorganizmalar
@Faydali-Mikroorganizmalar Год назад
@@MechanicGoneRogue It is not only more or high pressure oxygen, but the anodic reaction occurring on the aluminium side also determines the overall speed of the total electrolytic reaction. So I believe, using high pressure oxygen would not make very much difference. However, if you could also do something on the anodic side to remove the reaction products whatever they are, then this might affect the total output and then you may see a significant increase in the reaction rate/ capacity or output. Thank you for nice videos. I really appreciate it.
@MagicSpamDragon
@MagicSpamDragon 3 года назад
i think you should reduce it to about 4 volts then make multiple versions connected in parallel for example 3 giving 4 volts connected in parrallel then redo it 3 times connected in series to give high amp at 12vdc and if it is consistent non stop connect it too a 12vdc to 110/120 - 220/240 vac invertor for house hold power if you get modified sin wave at 50 hz 120 or 240 you can easily operate small appliances like tv, laptop, coffee machine, lighting if you invest more in a heavier duty inverter and get a true sin wave 60 hz inverter maybe power an AC unit or fridge (things with compressors have huge crank start power draw)

How does the battery not dry out? I mean, Aluminum reacting with water should produce hydrogen and aluminum oxide. So the electrolyte should run out, i think. Btw, thank you for the practical explanation.
@MechanicGoneRogue
@MechanicGoneRogue 2 года назад
Your right the battery does dry out. It takes about a day for that to happen though. I'm not sure if hydrogen is produced from this reaction, but mind you the battery isn't very big so if it did make any hydrogen I imagine it would be a negligible amount. I'm glad you enjoyed my video. Cheers!

What happens if you try to recharge this battery? Can you make a video? Can you see if recharging creates hydrogen gas? Can you try to capture any recharge-gases and prove that it's hydrogen? Can you see if some process can suppress the production of hydrogen gas, like using UV light or recharging in a pressurized container?

This is great for experimental purposes, but how would it compare with a standard AAA battery ?! It seams a standard AAA battery (much smaller in size than yours) has 50mA 1.5V, which roughly means 75mW, and yours is giving 5v * 12mA = 50mW. It might be that yours has greater capacity, as more than 1800-2600mAh like in the standard AAA battery. And I think that the capacity is after all, the characteristic that would make your solution fiable enough to make these on personal base use instead of standard cheap bought batteries. Can you make an estimation of how much mAh would your battery last ?! Regardless of the results, I say: Congrats, it's an excellent tutorial explaining the basics of batteries, these are not tabbu anymore, because of you !
@MechanicGoneRogue
@MechanicGoneRogue 3 года назад
@ Cosmin Popescu. In order to give any kind of estimation I would need to assume that the mA remains constant during the discharge duration. If that is the case I would estimate the mAh to be around 2000. As the long as the electrolyte doesn't evaporate (or more is applied). I've had some of my prototypes last for about a week before the aluminum is all oxidized. I really appreciate your feedback. I'm glad you enjoyed my videos :) cheers!

​@@MechanicGoneRogue This would be great news, thanks. So my idea on searching the web is finding a good recipe that accomplishes four conditions: (1) is 100% homemade possible, (2) is much cheaper that any commercial type of battery, (3) can be recharged easily by just filling an electrolyte or replacing a some sort of cathode/anode "cartridge", (4) has a good last-time-power balance, meaning I would have to "replace the cartridge" once a month or so. Do you think this would be possible ?! I saw on the internet that a big university discovered some years ago a form of simple tech that would use Magnezium FOIL for a battery that can achieve great power-time balance (30 g of magn foil would make an ios phone last one month, and they say it would cost only 9 cents), but I'm not sure where I would acquire magnezium foil, I mean cheap (I found something in Romania, my country, on the inernet but it was like 1000x (no kidding) more expensive that these guys said). This is the video i found most promising, what do you think ?!: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-3EKmetdjE-c.html
