I've experimented with quite a few variations of this with zinc bromide and run solar garden lights to test them. It's great fun and relatively safe chemistry to work with at a small scale. I must've missed the zinc iodine video, but I assume it's very similar to the zinc bromine. The cheap single cell Ni-MH solar garden lights you can get everywhere work great for these type of cells. They allow the voltage to trickle up to ~1.9V, limit the current and when its dark can, boost the voltage from as low as .4V up to enough to light a few LEDs. However, I almost always end up with the Cathode getting destroyed eventually! 🤦♂ No matter how well I thought I'd sealed the HDPE, somehow electrolyte would eventually seep in and try to destroy any metal it could touch during charging, almost as if it had a mind of its own! I had my best success using a pure carbon cathode (rods from zinc carbon cells), it lasted a good few months through the hot summer, died eventually in the autumn. The connections to the cathode eventually corroded, tinned copper wire and then 'stainless' croc clips! 😆
It's a bit of an outlay but you can buy titanium foil from Aliexpress in 1kg rolls that works very well in bromine. You can also buy it directly from the supplier for a little cheaper. I have made many zinc bromine batteries using titanium electrodes and the electrodes have never even been slightly etched! You can also use carbon felt with the titanium by crimping them together (the felt provides more surface area).
While you were going on about in and out and spinning your dingy, I looked up just in time to see someone with a pin wheel umbrella. They were pointing it at me spinning it and stopping it as you were saying in/out. When you stopped so did they. Cool video.
I want to create a battery that I can charge the liquid in one tank and discharge the fluid in a separate smaller tank. I think this would help with dendrites but it would also let the battery capacity increase based on plastic drums available
That could be a large lead acid battery, would need a LOT of individual cells to get 120 or 240V and probably not that many A hours at 240V but nothing to stop you. He said that one is only good under full load, that it discharged as soon as charging is finished.
I sure do love the battery videos. Do you have any new found additions to your lead / Carbon acid battery you built a few years back? I’m nearly ready to build some for myself.
Is there a pub near Canterbury? Near the business park? Aww, dumb question I know. I think its time for a Newcastle. What time does Bishops Finger open.
Just got 250gm of iodine from China for this type of battery!! Just as a suggestion, the carbon filled HDPE can be a little hard for others to get, so a video on making carbon coated electrodes with various substances like acetone melted ABS or polycaprolactone (polymorph pellets) with activated carbon might be helpful. I'll admit I don't know what iodine would do to it yet, but bromine seems to get through eventually 😐
If you use ethylene glycol instead of water, the battery lasts forever. Since ethylene glycol is flammable I was thinking of adding a small amount of water to lower the flammability. The cool thing about glycol is the zinc iodide is much more soluble.
You should be on the curriculum. Glad to see you are getting recognition though subscriptions. 🙂 Maybe tone down the adult film references. Happy new year.
I really like the all in one videos as they condense the educational information pertinent to task at hand Robert. Job well done and thanks for the information too. vf.
I like this. Raises more questions for me though. How toxic is the electrolyte? If the energy is stored in the electrolyte could you make a flow battery from this? Or is that missing the point and just a massive tank of electrolyte will do? Is the self discharge mitigated if it is used cyclically so it’s always either charging or under load. I’m guessing you are leaning towards storing the power from wind generation?
Nice one Rob, always a fascinating and video, reminds me of my visits to the Science Museum as a boy. Came across another version of the candle heater which might be of interest to viewers if only for its ease of available fuel (I think we call it lard in UK), video title is Winter Van Life: EMERGENCY HEAT and Light for 72 HOURS with CRISCO Candles! - cheers
Having conductive ink on paper, rolled up with carbon foam between, seems to me easier and more robust than HDPE. Is it hecause of the higher resistance that the conductive ink is not used?
What's roundtrip efficiency? I read that these can get upwards of 95% CE. My DIY aluminum battery charged up to 2.6v like a champ but self-discharge was a problem.
can we use stainless steel mesh instead of copper and not wrap it in conductive plastic? and will adding sodium sulphate compensate the increase in resitance as the battery charges? How is it relatable in terms of energy density to the zinc- bromine ones?
Halides (iodine, bromine etc) will attack metals in general (although titanium works good). Somewhere in Roberts' TnT channel are videos showing how to dip coat electrodes in a conductive coating made of a binder and activated carbon.
Awesome. I tried it a while ago. So when you make the solution very concentrated you'll have a higher energy density it seems? I'm finding it hard to source the carbon filled HDPE. Any ideas?
So if I needed to store energy this way. What volume of fluid would I need to say power a 12v desil heater. And could I charge this with the artificial muscle wind generator? Any risks like over charging. What sort of matinance would it need? Love all your videos. Heat is all sorted off setting electric is the thing that's confusing and would like to do in terms if the lights go out I got enough in storage power to last a few hours
This is still fairly new to me although I remember a wee bit from your past video. Certainly not galvanic action. To reduce or eliminate self discharge could there be a mechanism to remove the electrodes from solution until power is needed..or would the solution continue to undergo a reaction in their absence? I'm also curious whether zinc iodide has any special handling precautions or specific condition requirements that would prevent it's practical use in certain applications. Thank you kindly : )
I’ve been having thoughts about powering a house with a combination of many of the recent methods in the recent videos. Making biodiesel, using it to power a Lister D engine to drive an alternator to make a usable charge to fill a battery store to run the house/home. How feasible is it to do it this way? The most costly element of the whole system from my research seems to be a sufficient battery store. The lister and alternator being relatively cheap, the battery store and charge components etc being the major cost. I cannot see the downside save for my ignorance in combining the components. Any ideas on the subject?
Wouldnt it be possible to completly eliminate self discharge by pumping the electrolyte solution in and out of the electrode compartement? When you use the battery you pump the solution in, when you want to store the energy for a bit you pump the solution out into another tank.
Curious can you use urine as an emergency electrolyte with a copper strip and aluminum, or something that you would have available with you when hiking in the wild to charge a phone let’s say ???
Remember they have a thin plastic liner youll probably have to sand off. Foil may be easier. Im personally using cans for structural stuff (keeping shape of cases or hinges)
so you could charge it,then pour off the electrolyte into another container until you need it. And just pour it back in when you need a charged battery?
As I understand it; This is the what a "flow battery" does. My basic understanding tells me there is a chamber where the energy is generated and that energy dense liquid gets pumped to another chamber where it can be utilized.
Ok, question time. If you scaled this up to the size of a plastic barrel and maybe a bank or series of these. Could this be charged by single lightning strike, or build up of static electricity if you ground it to a span or areal? Essplain.
Love your work. Now is it me or has Robert gotten much more happy and cheery than a few years ago? Well bless him and wish him prosperity.

Come the apocalpyse Rob will be living like a King
Sad reality is that he will be killed quickly for extra salvage. In a apocalyptic world savages are first to gain power.
@Uncle Charlie🔧 good for you. I’ve just got plenty of hurting devices, not that safe tbh
@unclecharlie9022 unless your in the middle of the pacific you will be eaten or worse.
Great battery, Cheers, and a Prosperous 2023.
Looool this is why I love this channel so much. You get great humor with a great lesson

I've said for a long time that if I could hang out at anyone's shop, this one would have to be at the top of my list.

Back to batteries! 👏🎉

We need a battery that we can make inside a plastic 55 gallon drum to power our house... I love your videos! We have very similar interests.

Sort of like the energizer bunny Mr. Smith. I now understand Energizer batteries innuendo
Cheap batteries that work is always a good topic 🙂
Thank you 😊
I sure do love the battery videos.
Do you have any new found additions to your lead / Carbon acid battery you built a few years back? I’m nearly ready to build some for myself.
Can you do a follow up on how your giant radiator is still working.
Channel is gold mate.

The cool thing about glycol is the zinc iodide is much more soluble.
CE improved, I'd imagine

These batteries fascinate me, if I had more time I would attempt a full scale home build.
You sir have way to much fun! CARRY ON!👍👍
I always enjoy your videos.
Would it still work with gelatine in it like jelly to stop it sloshing around when moved
Robert, what happened to your graphine 'blade' battery and the 'Twizzy'?
You Sir are the kind of professor that we need...... As always - well done.
Hi there. You can bend graph foil with a roller to form a 90 degree bend very gently then coat the top section so it don’t short out the cell.
You can bend graphfoil if you put some support on. Like sticky tape will work,... just put 2 to 4 layers of tape around graphfoil
I did not see the 'adult movie' comment coming! Nearly spit out my drink!

This one I might play with.
The Bromine one concerns me.
I haven't really liked Bromine since I learned about Thomas Midgley Jr.
Seen that in a electronics magazine one time.

The Zinc must be mined, but the Iodine is found just about everywhere, like sea water or seaweed.
Could you press the dendrites back onto the plate with some kind of plate press?
Awesome. I tried it a while ago. So when you make the solution very concentrated you'll have a higher energy density it seems? I'm finding it hard to source the carbon filled HDPE. Any ideas?
Great stuff. Could you demo an Iron - Air. It would be interesting to see how much amps a small Iron-Air can output too...
And you do the Hokey cokey ! 👍
Thats what its all about ...
What about home building large 120V or 240V home batteries inexpensively while also being reasonably safe from fire hazards?

Hey undecided showed a windmill that looked like your wind wall :)

What stage is your commercial battery endeavor at? I can't remember the last time you talked about it.

That what you mean is called a flow battery. You have a tons of research on iodine flow batteries.
Reminds me of one time I sent you an email and managed to send something I wasn't supposed too . All that in and out business
Great vid, and very interesting. But I don't understand the 'gravity' part.
Curious can you use urine as an emergency electrolyte with a copper strip and aluminum, or something that you would have available with you when hiking in the wild to charge a phone let’s say ???
Gracias por la cátedra 💪
How would it go with zinc foam as the anode and carbon foam as the cathode?
How long does that battery last on that motor?
Does it self discharge if the zinc electrode is removed?
Nope. It will be ready to go forever with the zinc removed.
Why not coat the copper electrode with a layer of soot?
Perhaps this would be good to power a telegraph.
So zinc iodine and zinc cathode and copper anode wrapped in plastic?
Just as well those videos you watch with people putting it in and out didn't have a self discharge problem 😂
LMAO!
I have tons of aluminum cans.
I think I shall read up on how hard it is to do this with used aluminum cans.
Remember they have a thin plastic liner youll probably have to sand off. Foil may be easier. Im personally using cans for structural stuff (keeping shape of cases or hinges)
@@professorfukyu744 When I am done perfecting what I have in plan, I will publish it here so it can be duplicated.

either its April robert or ive made way stronger homebrew than I'd planned lmao
Double entendre!
I wonder if using sea water as electrolyte in a battery could produce deadly chlorine gases?
Yes

Nothing charges that fast, not even a capacitor.
