Fascinating work as always sir. I hope to share with you my own research shortly too, Ive learned so much from you over the years. You've inspired me to rebuild my lab and begin my own research!

@ozgurkaygisiz1562 Год назад

Hi cayrex2, your videos are very successful, thank you for sharing. Can the graphite plastic you made be used instead of titanium electrode?

@cayrex 11 месяцев назад

Yes you can for sure. That graphite plastic I use alot in my batteries years ago and works good.

@muhammadgattan8572 4 месяца назад

sir, I am trying to create the battery that you made, but it only produces a voltage of less than one volt. In my experiment, both plates are made of aluminum. Could it be that using the same type of plates causes the battery to produce low voltage? Thank you

Can we make 100amps battery by using air flow aluminium technology

@cayrex Год назад

Some companies make a Al batter that runs a car. This flow system is only here for pumping the electrolyte in/out. Which can help to stop the reaction between Al and KOH

@ivanrocha9808 Год назад

very good idea. How do you know if you are putting more energy into this electrolytic pump than the battery output charge? It seems like a one-for-one exchange... couldn't the pump motor be powered by the battery itself? or does the propeller provide oxygen to the battery? maybe both... thank you for your video!

@chipcode5538 Год назад

What about two cups and use gravity for the flow.

@cayrex Год назад

@@chipcode5538 the flow of electrolyte is only needed when you pump the electrolyte out or into the cell. When the cell is full of electrolyte,... the pump stops.

@cayrex Год назад

the flow of electrolyte is only needed when you pump the electrolyte out or in the cell. When the cell is full of electrolyte,... the pump stops. In tipical flow batteries you have constant flow of electrolyte and the pumps are powered by the battery when is dicharging and by grid when the battery is charging. But in that case you have a battery sistem of 48V.

@tami6867 Год назад

@@chipcode5538Well that would be cheating. Bc In this case the energy for pumping would just provided by Mr Batterys Muscles placing that stuff.

@chandrashekharkotekar3478 3 месяца назад

Great video as always 😀 Love your content. Can you please tell more about how much power is consumed by the pump and how much power is generated by the flow battery? Does battery generate more electricity than pump consumes? Once batter is working, can we switch electricity source for the pump from mains to battery?

@cayrex 3 месяца назад

If one cell will run a pump then the flow will be really slow. Because here I use 3 volt pump and one cell will have the voltage of 1.4V. For that reason you will need more cells connected together. The same way also work other flow batteries.

@chandrashekharkotekar3478 3 месяца назад

@@cayrex Thanks for quick reply. I was wondering if we can scale this system to run a electric hatch back car using this flow battery and how big the battery should be to run a car on it.

@cayrex 3 месяца назад

@@chandrashekharkotekar3478 In basic, this will not be a first time that some aluminium air battery will run a car. Good know is Israeli Al-air battery company Phinergy which put 100kg battery into the car. That Al battery in this video is almost the "same",.... but with a difference that this one is in a flow version which pump the electrolyte in and out when is needed.

@SchwuppSchwupp 5 месяцев назад

Suuuuper nice. Thank you for sharing your work!

@evil17 Год назад

Good job, nice little experiment. It would be nice to have some metering here to see what sort of power & efficiency you are getting. Could you still further your designing of the flow membranes to have the fluid flow more evenly around the cathode & anode membranes in a circuit like fashion making contact with both side of each conductor plate on entering & before leaving the cell? It would seem reasonable that by increasing contact area of electrolyte with anode & cathode would produce more power, if that is ur purpose here. Does the cell have enough power to run it’s own pump if you step up the voltage using a step up converter?

@cayrex Год назад

Hello and thank you. The point of the video is a Al - air cell that you can add the electrolyte when the battery is needed,... like a system in some flow variant. In that case the electrolyte can be removed from the cell which will stop the reaction between KOH and Al (in some research papers they replace KOH with oil). The one reactor plate model was not good because I get direct electrolyte flow from the one end to another end of the reactor plate with less surface contact of the aluminium. In that case I get 1.4V and 25mA. In the two reactor plate model the electrolyte need to flow from the first reactor plate where was also the cathode air material through the aluminium to the second reactor plate. In that case I get that the KOH make good contact from both sides of aluminium electrode. In the second model I get 1.4V and 300 mA.

@Dionysios_Skoularikis Год назад

Very nice work! What if you use aluminium sulfate as electrolyte?

@cayrex Год назад

Yes you can.

@jr-pl9kj Год назад

the problem with this battery design is that it still consumes the aluminum, then you'd have to take it all back apart and replace it with a new one, what a mess and not practical for me, I'd rather have the electrically rechargeable alternative to this battery the aluminum ion battery.

@cayrex Год назад

Yes I know,..... but this is only the first video of this series. I was thinking of that problem of replacing the aluminium,... but this will come in another video Correct. The cell consumes aluminium as a fuel.

@MrVeryCranky 11 месяцев назад

You need to pump it out through the lower outlet.

@gencocaglayan922 Год назад

why you need extra power connect pump is battery?

@cayrex Год назад

Because here I have only one cell and the pump need 2.5 to 3V. The pump in orginal setupe is connected to the 12v, 24v or 48v battery (multiply cells).

may I ask something, how long does the battery reaction last?

@cayrex 10 месяцев назад

Hello! Depending on the aluminium and electrolyte which is used in the cell. Thiner and more concentrated is the electrolyte,... faster will be the reaction. In one of the experiments I use 1 gram of aluminium in 2M KOH solution and the reaction last for 5 hours.

@rickway2039 8 месяцев назад

@@cayrex 1.4v at 300mA for 5 hours? That puts it right on par with a nicad double A. Lower amperage, but longer running.

@evanriddle1614 11 месяцев назад

I wish there were something we could pump into the electrolyte's place to preserve it. A type of laboratory PAG oil has been used but mineral oil might work too if it doesn't foul the carbon cathode. Thanks as always!!!

@gsestream Год назад

You could also just freeze aqueous electrolytes,to stop them from being conductive and corrosive, ie, not being electrolytes, anymore, ie throw the battery in the fridge

@gsestream Год назад

so do you assume the flow of water electrolyte brings the oxygen, or do you make an air inlet on the block

Can you make solid state aluminium air battery?

@cayrex Год назад

More like solid polymer gel Al air cell, yes.

@tami6867 Год назад

solid state battery is likely not possible, or not rational. Liquid electrolyte is there gor the ion exchange and increasing the reactive surface in a battery. So you'll end up more likely with something called an almost solid battery, where there is a little fluid electrolyte left.

another good video.. I see a lot of possibilities in aluminum batteries.. definitely want to start experimenting with them myself in the near future.. but I am struggling with the solution for an air cathode.. and I didn't think you were using a air cathode in this project.. do you have a suggestion to make an air cathode yourself. or is it not necessary at all when running the flow model as the liquid will draw oxygen into the cell.

@cayrex Год назад

The air cathode here is made from activated carbon felt and the reactor plate have also a air flow channel which goes to the cathode material. Usually the air cathode is made from some activated carbon and catalyst.

@westcoastangler9839 Год назад

@@cayrex ha ha ha i have studied your video one more time.. i had completely overlooked the little gap.. sorry, will probably pay more attention in the future.. I assume that the reason the pump does not pump electrolyte out of that hole is because the flow is so slow that the battery's "need for air" creates a suction/vacuum in the cell itself
