Was once installing a production line in a Mexican factory at 2 o’clock in the morning when we needed to check the polarity of a magnet. No tester! I sent my helper to go make coffee while I “thought about the problem”. Of course I had already formulated a plan based on something from Mr. Wizard. I snipped a piece of steel spring wire, straightened and magnetized it. Used whiteout correction paint to mark one end. When the coffee arrived my man was aghast to see me float the wire in it. But as it spun around I asked him which way was my home. (The North end of the wire points to a South pole of a magnet which is somewhere in Canada these days). Mr Wizard saved that company $3 million because the line was installed on time!

So clay sewer pipe and charcoal bricketts a 55 gal plastic drum and a wad of old chainlink fence and you have a big cell . You could just drain the electrolyte into another drum to turn off . Placing the 2 drums on either end of a tetter-totter to eliminate the need for a pump. Placing the drums on their sides would shorten the lifting hight and a sliding counterweight on the tetter like on a beam scale takes the work out of lifting the drums with the tetter.

my guess is it will be down to the break down of the separator and thus the ability to form dendrites between the two plates, shorting it out, the better at resisting that, the longer it will last and the dendrites forming on one side to form more of a foam like surface area, would cause it to discharge faster and release more amperage and thus making the use of it breaking it in so to speak.

You'll probably have to top off the water due to evaporation, but I don't think it produces hydrogen or anything like that. 1.2V is right on the borderline of when electrolysis starts to occur, but it usually takes a bit more than that. Raising the pH can reduce electrolysis, but unfortunately, zinc hydroxide is insoluble, and you don't want too many other metal contaminants or you'll just be wasting power. Just look for bubbles I guess.

You sometimes find them in emergency locator beacons, because you can still depend on them even if your emergency beacon has been sitting forgotten in the bottom of the life-jacket locker for the last thirty years.

Lugol's iodide has several other uses including microbiological staining of bacteria using "Gram-staining" During which the iodine from the Lugol's solution and crystal violet form a stable complex that will not be released by decolourisation. Thus, Gram-positive bacteria will appear dark blue when viewed microscopically, whereas Gram-negative bacteria can be counterstained with safranin or dilute carbol fuchsin.

Lugol has an Iodine concentration of 1%. This is a molar concentration of ~0.08M. This gives you an energy density of ~2 Ah/L at 1.2V that is ~2.4Wh/L. Lithium ion is 250-693 Wh/L. So this battery configuration is 100x less energy dense than a lithium ion battery. You will need to increase the I2 concentration by a factor of around 100x to make this actually dense enough to even come close to Lithium ion. However you cannot, because the max solubility of iodide is around 6M and only a max of 66% of the capacity is accessible without precipitating solid I2. The Zn-I chemistry is awesome, but to say it competes with Lithium ion for power or energy density is misleading, at least for the chemistry using purely ZnI2.

These are real flow batteries with real efficiencies and energy densities being measured. My results right now with microporous membranes for Zn-I are around 35 Ah/L, lower than the state of the art since I want the higher current densities and low cost of a microporous membranes, but even the state of the art on research papers is around the very low end of the Lithium chemistries. It is great to encourage people to explore these chemistries but to tell people that they can build a rechargeable battery with the same power density than a lithium ion battery in their kitchen is just very misleading. That's not even the case for the best papers. I think your videos would improve a lot if you also went into why these chemistries are actually not being used right now, because you make it seem like industry is just dumb and all these obvious solutions from the 19th century exist. There are very good reasons why Zn-I and other chemistries are not the dominant battery chemistry atm, despite Lithium ion being much harder to manufacture. It would also help people to see the actual efficiencies and capacities of the batteries you build (CE, EE, Wh/kg, Ah/L, etc). You have the equipment to measure charge/discharge cycles and give actual data. With proper data, there won't be any potential for statements being misleading, the data will speak for itself.

I didnt have carbon fiber or even carbon rods so i bought the thickest mechanical pencil lead i could find, and apparently in the USA, elemental iodine is restricted, so i bought providone iodine antiseptic. I got 1.3 volts out of it, and interestingly i get 1.28v when the electrodes are not seperated by the clay pot and 1.30v when they are. Anyways, my question to those more knowledgable to me, is there anything inherantly worse with iodine antiseptic vs just mixing it up from the raw elements yourself? I was considering boiling off the water of the solution to give more a more concentrated, and, i think, more energy dense electrolyte, but i am an absolute novice at chemistry and i barely understand enough to even know how to look up the information i need at this point.

What happens to the potassium? On a larger scale would the potassium interfere with the battery?

Thanks Robert, very useful information,but how do you dispose of it ,safely? Genuine question as the longevity of this is obviously limited and the components will need to be replaced.

As a improvement to the battery couldn't you add some of your organic graphene to a batch of clay with the temper material and make conductive ceramic terracotta? Couldn't you layer a bit of normal terracotta to the outside to act as your permeable barrier? And mechanically to take the zinc out of solution, just have a manual crank. Though I can see an issue occuring where bits of zinc might break off and keep the cell running at low capacity. And long term, it might be good to discuss how to recycle or dispose the materials used when they are used up.

What if the zinc electrode is a kind of flexible base-electrode where the zinc could stick to it? I don't know if the same carbon fiber can be used for that, giving it the capability to be folded or rolled like paper in order to be removed from the electrolyte

Does it require any special charging profile or will a standard charge controller work?

I wonder if it would be possible to 3D print a semi-permeable membrane(or similar structure) that would facilitate a modular battery approach with this chemistry?

That is a fair point! As far as I know there are only a couple of off the shelf printers that will print Ceramics and clay, but that would certainly do it!

So this is a Primary battery and not an accumulator? Any suggestions on an accumulator, i.e. a storage battery. Salt water batteries perhaps?

Hi Rob. In Australia the iodine and potassium iodide are restricted chemicals in its raw forms. I can get some lugols.

Could you try making a sodium ion battery?
@vylbird8014
Жыл бұрын
No. The problem is that sodium alone wouldn't cut it - if it were that simple, we'd be in mass production already. Sodium doesn't last. To make it stable you need to alloy the sodium with various other metals, and not many people have a home workshop suitable for mixing alloys under inert atmosphere conditions. You're looking at mostly-sodium with carefully measured and mixed traces of magnesium, manganese, nickel and iron. Maybe cobalt, as a last resort. The electrolytes are even harder to make. Sodium ion batteries are /hard/.

I wonder why i never heard of these. It seems with economy of scale they could easily replace things like teslas powerwall for way less money.

great, we've been waiting for your videos on batteries for a long time!! ;-) exciting as always. zinc iodine is a very nice couple! for dentrites ethylene glycol would be a solution (cf:science-direct) on the other hand: iodine is prohibited from purchase in most countries in Europe... and potassium iodide is accessible but costs a fortune (~3000€/25kg) the investment could be "worth it" if we knew the lifespan and the number of possible cycles... for off-grid storage (this is something more and more people will need!) which DIY solutions would be the most relevant/reliable in your opinion? gelled ultra-battery, super-capacitor, iron redox flow, chlorine battery, iodine battery...? with obviously as little rare earth as possible. thank you for your work, I always admire

I have tried to replicate your results with the zinc iodine battery and have been successful at getting around 1.2v but every time i put a load on it i can’t get any Amps out of it. Any thoughts on what i might have done wrong?

So what's the solution concentrations?
@ThinkingandTinkering
Жыл бұрын
there are no fixed concentrations mate - all will work - by increasing the concentration you will increase energy density but there is a limit - of course - and that is the limit of solubility - there is also a playoff involved in terms of the solubility of the product - but when it comes down to it really isn't crucial at all
