Very groovy. Thanx for sharing your walk throughs.
And it's nice that you spoke about it rather than blast out some looping music file.
Keep on rocking like you roll.
How practical would it be to replace the carbon electrode with a ribbon of carbon fiber, use fiberglass separator, and roll the whole thing into a compact cylinder?
Wow red gas! Looks cool :) Thanks for sharing Cayrex.

Hi, thank you for sharing! One problem though is high solubility of iodine in electrolyte as I3- resulting in diffusion over to zinc anode and high self discharge. You could try reacting iodine with AC through heating to form AC-I addition products, then once this is chemically bonded to surface of AC, it is stuck there and can be oxidised to AC-IO3 etc. in alkaline electrolyte. Possibly that will keep iodine on the cathode side, also higher voltage can be obtained by Zn in alkaline conditions. Please try this, I would love to see!
Iodine bonded AC electrode I use in my previous video. About Iodine in alkaline electrolyte like KOH or NaOH,.... will not go into KI / KIO3,...
@@cayrex Ah okay, there was no commentary there so didn't know what you were doing.
If I had a bucket full of Euros, I would have long time given to you. I really enjoy and learn from your work. I wish that I could support you financially. I am trying to also develop very affordable battery for rural area use.
No panic
Are you suggesting that you don't own a bucket, or that you are flat broke?
But if Euros did happen to magically end up in the bucket (not that you would actually put them there yourself) you'd just ship that bucket right over because you're SO grateful.
Don't say stupid s*** you don't mean.

Thanks for sharing. Nice simple electrolyte. Fairly inexpensive.
My skin is still crawling from scraping the powder!!! 🎧 😂
my understanding of the Zinc Iodine flow cell is limited but I thought that iodine crystals blocking the flow channels is one of the potential problems that this combination exhibits. This isn't the case with the hybrid cell, right? (but at the expensive of no longer have the usual capacity/volume relationship that the full flow cells enjoy).
Are you working on ‘sub millimeter flow cells?’
Quick Question regarding your Nickel-Zinc batteries. I know its not related to this one, but I have been watching multiple videos recently! What is the piece of metal that you attach to the NiOOH electrode, from which you then use a gator clip on? It appears to be crimped onto the electrode. Please let me know if you can help describe what that is!
Please, how do you make an electrolyte solution or some materials, what kind of mod please and thank you. Greetings to you
This is great. Thank you.
No problem.
Thank you very much for the video. Cayrex2! I'm messing around with a Redox flow battery. And I was walking around in the forest and do you know anything about tannic acid? There are millions of Acorns laying on the ground where I live. So I thought maybe extracting the tannic acid (TA) from them. I belive this may work as a electrolyte what do you think?
Oh RFB, nice. Tannic acid,.... you have in coffee, tea, wine, grapes, etc. Tannic acid as freestanding electrolyte,... emmm not so much. But I hear that was used as electrolyte additive in Li ion battery research.
@@cayrex ya I just started looking online and see a lot of research is being done on TA. seem like it's not just for lithium ion. I just read it make activated carbons more conductive. When mixed. So maybe if mixed with your conductive ink may improve the conductivity? Just a thought.
The question of the million: Is it rechargeable?
I suppose you could try it with a lipo battery charger but that would require some testing to find out what the right voltage is to not blow up
Yes they are
Now put up a wire 200 ft long like 30ft up in the air well insolated...with maybe graphene strips every few ft on sanded wire spots .then connect it to your battery if it's two strong..that's 1000 voltage but low amps ..try a dc to dc converter to up the amps and lower the voltage.. with this you might be able to run some things in your home by charging 24/7/365 real good system no harmful chemicals and rechargeable batteries doesn't ware out .
You realize that the best electrolyte to use is Ethylene glycol. Zinc sulfate is more soluble in EG.
Is good but not the best. Yes I know that ZnSO4 is more soluble in EG. I make a cell which use that ZnSO4/EG electrolyte (and also ZnCL2/EG) several years ago, I think I also need to have some video about that. Using EG or EG with water is good for making cells for low temperature environment.
Very interesting and nice 👍
Have you tried (POTASIUM PERMANGANATE)? Thanks for sharing your knowledge with me.
thank you so much for your teachings. if i cannot find iodine crystals in my country, can I use tincture of iodine instead ?
Good source of iodine is also potassium iodine
@@cayrex thank you. i get it. i think... are we talking about KI or KIO3? if it is KI i will extract the iodine from the potassium iodide is that right ? thanks
@@samosdolphins123 you can use potassium iodine or you mix KI and ZnSO4,.... then you will get ZnI2 and K2SO4
@@cayrex oh thanks ! that sounds much easier. I guess a visit to the beach is in order to get myself some potassium iodide. :)
@@samosdolphins123 Yea! In solution of potassium iodine you put two carbon rods and you apply some current,.... and you will get the iodine on positive carbon which will be dissolve in solution. If you have potassium iodine and zinc sulfate in solution and you apply some current to carbon rods,... you will get zinc plated on negative carbon and iodine on positive.
Bromine has left a bad taste in my mouth since I learned of Thomas Midgley Jr, the inventor of Tetraethyl Lead, and Chlorofluorocarbons.
He actually had two contenders for the refrigerant, that and Bromofluorocarbons. Bromine is in the same chemical category as Chlorine and Iodine.
Thomas chose, rather arbitrarily and capriciously, at the last minute, to use Chlorofluorocarbons, and not the bromo.
Because had he chosen Bromofluorocarbons, the Ozone Layer would have been dead before we knew there was a problem.
Have you done a calculation of watt per mole of ZnI2
Watt per mole? No
Does the iodine evaporate where you live? I live in northern Australia and if I leave anything with iodine out it will disappear!
Iodine will color the surroundings to dark brown stains.
@@cayrex I think the reference is to very high vapour pressure of iodine. Do you know of a way to stabilize this for long term use? or just make sure the battery is very well sealed? Thanks
Nice
but zinc iodine batteries have a lot of self dischrge?
Yes and no. Depending on several factors like how is made the housing, cell construction, additives, preparation of the cathode, etc. For example one of my zinc iodine batteries which I test the self discharge, I get from 1.314V and 0.72A to 1.268V and 0.61A in 5 days.
@@cayrex wow that sounds impressive. Carbon felt? Check out my zinc iodine battery video I posted. 24 mah from 2cm square
@@cayrex any tips to reduce self discharge?
it would be nice when you are making batteries to state if a certain electrolyte chemical mix can be dangerous or not . . you are an expert but not all of us on youtube are chemical experts so we don't know the consequences if you don't tell us . . thank you
if you have to use gloves in home environment, its not suitable for general public
hahahahha,.... ok😂. You know that Iodine leaves brown stains, right?🤦♂ In the end no one is forcing you to make it anyway.
@@cayrex I meant anything that requires gloves, not limited to iodine
@@Jkauppa Aha ok 👍
