Many problems: First, during discharge, your anode product is soluble in your electrolyte. That is to say, the iron chloride being formed at the (-) plate during discharge is itself soluble in the iron chloride electrolyte. This introduces many problems. For one, you therefore don't have a reversible reaction at the (-) plate.... i.e. you can't recharge the battery. In other words, you can't 'force' the iron chloride swimming around "way out" in the electrolyte to reduce again to elemental iron and re-join the anode substrate material. That would be trying to plate iron onto more iron from an FeCl2 plating bath using a non-iron sacrificial electrode (graphite), and that doesn't work. Iron plating onto more iron can be done, but is extremely difficult with complicated plating chemistry needed. In an Fe-Ni battery, as an example, the iron oxide stays on the (-) plate. It never leaves, because it's not soluble in the KOH e-lyte. It just oxidizes in-situ and doesn't migrate out into the e-lyte. Therefore during recharge, it can reduce back to elemental iron right on the (-) plate. Thus, you can go back and forth. Same thing over at the (+). The various Ni oxides never leave the (+). They oxidize and reduce in-situ, because they are not soluble in the e-lyte. Secondly, during the charge cycle of the cell in this video, depending on the voltage used, all you're probably doing is getting a little Fe to 'plate' onto your carbon in sort of a spongy mass, and generating chlorine gas over at the steel plate, and/or electrolyzing water and oxidizing your nicely prepared carbon. You said you charged up your battery for 5 minutes before running the car? What is powering the car then is most likely oxygen and hydrogen that was formed via electrolysis of water during the charge cycle. You have made a simple fuel cell in essence, which is a nice demonstration in itself, but not really a Fe-C couple. Suggest: Choose an electrolyte such that the anode product-of-discharge (iron chloride) isn't soluble in it. That's why we use KOH or NaOH with batteries having a steel (-) plate. KOH is more conductive than NaOH, and a little less nasty to work with, that's why it is used. Since you want to utilize carbon at the (+), why not make an Fe-Air cell? You're almost there already. US patent 3,649,361 (General Electric) lays out a simple method for the Air-side which doesn't require a noble metal catalyst. Or... paint your (+) with Ni(OH)2. Utilize a Tyvek separator. Use KOH e-lyte. Thanks for posting your work. Very interesting commentary.

I bought it quite a while ago and don't remember the exact price at the time but it was about the same price that they list it for now, $175. I really like this MK-201. It has proven to be very reliable, accurate, and versatile. Here is the link to purchase one: www.batterymetric.com/mk-modules/. It is a great value for what it can do at that price.

No, it is grafoil, that can purchased from eBay or Amazon. The anode has to be iron because it plays an important part in the chemistry of the cell which is oxidation/reduction of iron.

Instead of using Grafoil sheets you could try painting a sheet of paper first with a conductive paint/ink. Then coat it with the active carbon ink. Refer to Robert Murray-Smith's videos on KZitem on how to make your own conductive inks. He also sells inks on his website ( secure.workingink.co.uk/working-ink-shop/page/2/ ) . Initially, I would stay away from any metals, like copper on the carbon cathode because in my experience its hard to seal off any metal collector completely enough to stop copper or other metal interfering with the cell chemistry. I've tried using/reusing thin Graphite blocks as electode collectors but they are surprisingly porous and absorb/retain electrolyte salts which contaminate the electrodes if you reuse them in other cell Chemistries. Grafoil is preferred to graphite slabs because of the weight reduction. A good conductive ink on a non-metallic inert sheet material should work OK and worth a try.

You will have to experiment with binder amount, adding just enough to hold it together but not sacrifice conductivity. You will also need to add a little water to make it into a paintable fluid.

Hello William, really great job. 😉 I don't know if you're still present to comment. A question I have is about the kind of battery it is "really" , because often the iron based anode batteries presents lower volatges (it's not exactly the case here, kind of mysterious) : - Is it more a kind of supercapacitor on the positive active material? (acting like iron phosphate pseudo capacity in lithium cells) - Or some kind of internal oxygène breading (the oxygène is some how regenerated at ech cycle ) - Or just the carbon that makes the differential potential (theoritically in "average potential" of the table) and maybe the highest energy links between chloric and ferrous ions that help incrising the oxydo reduction difference (during ionic spliting) Sorry if my technical engligh is not perfect, I'm nether English (an awful French)... nor chemist ☺

Thank you! I believe the overall chemistry of my cell is probably this redox reaction: Fe + 2 FeCl3 -> 3FeCl2 , Eo = 0.77V Eo = -0.44V Eocell = 1.21V. So 1.21 volts is the the theoretical voltage and it looks like my cell is getting close to that output. I guess it's possible that it could be partially acting as a super capacitor but I don't know of any way to prove that. I don't think that it is an iron/air battery because the cell is sealed , completely closed off to the atmosphere, and doesn't have an air breathing cathode which air batteries require.

Maybe also try some more common stainless steel cathode electrode, supposed to be oxydo resistant and cheaper (I don't know for the catalist reaction - to be tested).
