Diy Rechargeable Salt water battery 

I was searching for a flow battery solution with only the liquid as a energy source. So a bigger tank, simply means more storage. So thanks for the info!

You know you have reached expert level battery researcher when you use the terms anolyte and catholyte 😉 Enjoyed the video, thanks! Also loved the music in this video!

Great stuff. You make great battery videos. I would like to see you create a diy membrane for a flow type battery.

Nice demonstration! Really interesting cell.

So weird how great minds think alike! I was researching the other day how to make one of these at home... Appreciate the video! Has given me some new ideas! I'm so glad to see I'm not the only one doing these weird at home experiments haha

Could HCl and NaOH be used to start with or do you have to have the power input to populate the electrodes? Many thanks. Always watching. I had no idea you could make these chemicals from just table salt.

Nice video my friend. How about some vegetarian gelatin instead of Nafion membrane?

Good job sir very interesting

I understand soduim sulphate offers a wider voltage window. Upwards of 1.5-4.0 volts

Still watching you mate 😎 Very interesting !!

My friend, this is next level.

Hey man, i'm pretty new to the channel, but i've stumbled onto this video because i was researching salt batterys for a school project and altough this video is great to quickly learn the basics, i did have a few questions about the material used: 1. U use some kind of ion exchange pad, which is needed to sufficiently make a salt water battery, but they are hella expensive, the one you are using however seems really usable, since the surface area of the membrane itself seems small, did you make that urself ore can we buy it somewhere? And where did you get your membranes? 2. If i 3d print the parts, i assume i cant use pla, since the acidic environment will eat it away, any tips on what filament to use instead? 3. Since im planning on 3d printing it, but i dont have acces to an resin printer, so i cant print rubbery materials, any tips on stuff i can use to make it water tight? Some kind of rubber? or can i use silicone sealant for that? And lastly: any overall tips to make it as efficient as possible? Love your work man, its really helpful! And if you share the info i will assure you i will only use it for the school project, As a form of communication: I will also post this on you latest instagram post, u could message me there, or just reply here.

Fantastic demonstration! Do you know how much performance will degrade with a larger gap? For example the radius of your container between electrodes. And I'm wondering what the highest specific power would be given that the conductivity is quite low.

Interesante es pila recargable felicitaciones.. Has hecho pruebas cuanto tiempo mantiene la carga en reposo...

So good, thanks for sharing For some time now I had been thinking about the possibility of making osmotic membranes using objects from nature, for example, the skin of an onion, or banana leaves, or bamboo pods, cuts from tree trunks have been used. of the lime tree, of a few millimeters to desalinate seawater, successfully I think some types of wood cut crosswise could be used, it is a good essay topic. all the best

I was half way through the video when i jumped to make a comment proposing making this battery to a simple flow battery. I made that comment and then proceeded with the video only to be pleasantly surprised. Charging and discharging could be done with the motors in series so the pumps work with current during charging and discharging.

Excellent video and very interesting! I am not sure if this reaction produces HCl though. Sure the equation balances, but would you not just rather get water containing dissolved Cl2? I think that will also test as an acid. Anyways you have my attention, i want to try it at home!

Can heat rising fluid suffice instead of motor pushing liquid? Or density bouyancy of different densities perform the flow?

I have forgotten if this was mentioned but would their be any reason not to add koh3 into the mixture ?

Hi😀 very interesting stuff. Which of the two demonstrated cells has a larger storage capacity and aproximatly how much storage can it hold? What would be expected lifespan for each of the two batteries and how is efficency? Awesome channel, i've just helped u via paypal😁

Hi there. very interesting stuff. i have seen all ur videos and was wondering would u do a followup on the vanadium flow bat ? and if u would build a flow battery what chemistry would u use? thanks and keep up the xperimenting

Yeah it's a good demo for a simple battery, just unfortunate that it requires an expensive membrane. Wonder if PTFE tape might work since it's from the same chemical group? 😁

Hey do you have any good recourses that explain gel polymer electrolytes on a high level? Could you please share any sources?

Hi @cayrex, the 3d printed models you used, are they somewhere available online?

Can you have a natural circulation like those acid and base are going to separate like emulsion or so so if you have a displaced reservoir are they going to sor themselves ?

Nafion looks expensive... Is there cheaper alternatives?

Is this a sodium ion battery like north volt is producing? Do they use manganese as we'll?

Can you start using hydrochloric acid and sodium hydroxide as starting materials so it would be charged already?

Very nice! It would be good to measure the total capacity of the small battery and efficiency of charge. Also make some projections of the possibilities if scaled properly.

From one Made-In-China Fuel Cell many informative videos, that's crazy 😂

Its a lot cheaper than vanadium. It would be interesting to see some comparisons between your 2 flow battery chemistries using your electronic load showing graphs. 👍

Seems like you will be depleting the electrolytes, with losing cl2 and h2 (charging at 2.5V). Or do you think you are just moving concentration of h+ and thus have a type of concentration cell?

Allegedly some cheap natural membrane can be made from banana peel, egg shell membrane or sausage casing (animal instestine) 🤔🤔

Very nice, what is the current rate of this stop?

super cap? or just hydrogen oxygen gas storage battery. well another salt like baking soda would make oxygen not chlorine. chlorine hydrogen gas fuel cell battery? the membrane makes two compartments for the two different gases, keeping them apart but lets ions pass through. hydrochloric acid battery. oh there is also NaOH in the solution, on the other side.

So a chlor-alkali plant in reverse

Nafion membrane's ?

How can we make use of simple ingredients to make a minimal power supply for emergency use? I have been searching/researching this for some time but keep hitting a brick wall. There are so many scammers out there, eg. people who claim that it is possible to make batteries using sparkplugs is possible. Many people say this [spark plugs] is a scam.

What is the power output? density and so on?

What kind of membrane are you using?nation?

Is it completely specular? Can it be reversed? I mean polarity? What would happen?

this is the coolest thing i've ever seen, why cant this be used in a electric car? instead of expensive lithium.

Why don't you buy a pH pen?

Katode dan anoda mengunakan titanium ... apa bisa diganti Chromium ?? Sistem hampir sama Vanadium baterai .. Katoda ::: Ti ----> Ti2+ Ti3+ Ti4+ V -----> V2+ V3+ V4+ V5+ Anoda reaksi asam Chlodide Cr , Mn ion sama vanadiun dan Titanium , Apa bisa digunakan ??

Sorry all of this question but I'm a noob
