The SULFATE in the zinc sulfate turns into SULFURIC ACID and eats up the graphite anodes in about 3 weeks! No good!

The Creator God of the Judeo-Christian universe exists and has a name, His Name is above all names, His Name is Jesus of Nazareth. my book of deaths twice Because I had a dangerous illness in my intestines and unlike Joram, the Lord had compassion on me and did not let me die in that tortuous, painful and humiliating illness. His mercy is more beautiful than beauty and through his mercy I breathe and live. It has also freed me from other illnesses such as mental, existential and spiritual as well. He who humiliates himself does not despise

Congratulations for achieving the first scalable Graphene based Zinc Ion battery. I would love to see you improve this chemistry further, get energy density in Wh/L and maybe you should consider making graphene on your own. Graphene can be made by either glitzing polyimide tape (Kapton tape) in a 40W CO2 laser or by putting whey powder and graphite powder in a blender for 45 mins in a particular ratio.

I can really appreciate people who share their builds and ideas with others on platforms like this. Thank you. I have a few simple questions that I may have missed watching this video. How thick is your zinc material? I have some 99.9% pure zinc plate with a thickness of .2mm and I hope this will be OK. I want to run something else by you for you to possibly try and I too will try this and if it works out, I'll make a video and upload it and give you credit for this information. Here's what I want to run by you. Have you thought of using a piece of round PVC pipe for the container and building the cell up somewhat in the form of a standard A, C or D cell? You could do the same configuration but use the PVC as the hard shell and line the inner diameter of the PVC pipe with the zinc followed with a circular piece of plastic mesh to give the zinc the needed space from the carbon electrolyte mixture. My last question is when you top off the battery with the electrolyte is it to the level of the height of the battery. I realize that may sound like a dumb question but I want to be sure so when I try this I get as close to doing this right the first time as I can. Once again, thanks for putting this information out there for others like myself to see and build. Take care, Flash001USA.
@microphotography2090 5 ай бұрын
Yes, using a cylindrical body such as a pipe should work. However, keep in mind that current collection surface is reduced in a round cell, which is why a more flat pouch cell will yield better power output. Yes, the electrolyte needs to be just at the top of where the active material ends because there is physical separation, but leave some head room at the top for expansion during charging.
@flash001USA 5 ай бұрын
@@microphotography2090 Thank you for replying back. I can understand your point on the surface area limitations on how it can affect the current and I thought that you may have already even tried this yourself. When I receive all of my materials I'll shoot for a few different configurations and see what happens and if the results are decent I'll make a video and share the information with others. Once again, thanks for the video.

Wow! That's really interesting! I also just commented on your previous video (from last year?) as I'm trying to design a homemade battery pack for my tent trailer when camping for 4-5 days at a time. I was originally looking into potassium iodide but it seems a bit difficult to obtain the needed materials in a cost-effective way in Canada... :| So your previous videos definitely made me quite interested as they provide a definitely very interesting alternative (and probably way more cost effective at consumer prices!).
@ragnarok700 7 ай бұрын
Wow, this does indeed seem quite convenient. I'm looking into designing a battery pack for my tent trailer for next camping season ( in Canada too :P ) to last me 4-5 days at a time. I've estimated my needs at about 700 Wh (before DC-DC boost converter efficiency loss and other electronics), so I'm probably looking at a making a 900-1000 Wh battery pack to alleviate various inefficiencies and compensate for cell aging, etc. Do you have any recommendations on materials to read/view/consult/etc. to help me move forward with such a project? I have a good basic understanding of the required knowledge (did a b.eng) and I read a lot about all these things... but I just want to (finally) get started, you know? :D

@microphotography2090 7 ай бұрын
Fully rechargeable. It actually gets stronger each cycle. The most cycles I've ran was 35, and it was still increasing in capacity each cycle(The increase was diminishing though). After those cycles I moved on to other tests, it's just too early to be doing mass cycle testing(Especially since my testing units are broken and do not auto cycle anymore, I have to hit the on button every cycle).

A little bonus explanation: The battery in this video is roughly 10 watt hours, and peaks around 50 watts output. The battery is smaller than it looks, without cardboard spacers between each cell, all 6 cells are only an inch thick when stacked. This battery chemistry was a bit of a fluke for me, I usually make carbon black based zinc ion batteries, but recently discovered an electrolyte additive that has a fascinating effect when used with graphite foil. The effect happens when overcharging, instead of the foil flaking off in thick sheets of graphene, it holds together while at the same time exfoliating internally. It's like thousands of pages in a book spreading apart. The effect creates huge surface area and energy density near lithium. I theorize a portion of the exfoliated graphite is graphene. Regardless, the surface area is so immense and the sheets are so large, I wouldn't even think it would matter how much is considered graphene and how much isn't. Unfortunately this is all the info I can give at this time, since I am still really early in this research, more detailed videos will be coming to this channel.

@@comfortpooe7588 i think many paper is fake information, how can the battery survive thousand cycles while it corrode and passivation layer form, i am not electrochemistry expert but i have hypothesis Corrosion is because oxygen from water and acid react to zinc (but i test aluminium foil doesnot corrode in ZnSO4) Passivation layer is because not perfect ion reversing process , what i mean is when metal or something become ion , or back to metal while charging / discharging, its cannot back to original state perfectly so it make passivation layer. This is really differennt to aluminium ion battery, because no clear sign of corrosion and passivation layer of aluminium foil using ionic liquid which free of water
