- Hello everybody and welcome back. Titanium dioxide wouldn’t have been my first choice for improving my battery output, but as I’ve now found out. It works! Not only that, but the entire process is quick and easy. I hope you all are pleasantly surprised like I was. Thanks for watching.

Another one so soon
and with fire?
LETS GO
Yessss!!! The idea turned out to be so simple I was tempted to try and mix it into a larger video. But I decided in the end it deserved a video on its own. :)
@@MechanicGoneRogue I personally like it, it's more qualitative and a breath of fresh air than the more number geavy optimization videos
Oh Yah! I'm really happy to hear that. That's what I'm aiming for so I'm glad I hit the mark.
@@MechanicGoneRogue then flawless execution
Try K2CO3 in water as the electrolyte, then you will get about 1.33 Volts from the cell and add some MnO2 as a catalysator to even boost the cell some more. Good luck ! Regards, Stefan.
Hi there Stefan. Just wanna say thanks for your comments and suggestions. Do you have any resources I could check out for more info on using K2CO3? I'd be interested in reading up on it. As for the MnO2 I've heard about it, and am experimenting with it currently. Seems to be the best catalyst around for these kind of batteries. Cheers!
@@MechanicGoneRogue it is potassium carbonate you will get 1.33 Volts per cell from it..👍🏻❤️🙏🙏🍀🍀🍀
Takes a bit time at the beginning, until the K2CO3 has reduced the aluminumoxid protection layer
OK well I'll be sure to try it. Thanks again for the suggestion 😊
interesting monitor setup haha
I know right. The monitor is like 20 years old too, but beggers can't be choosers.
Can you test adding tiny amounts of cetyltrimethylammonium bromide to electrolyte. This will increase the surface tension of electrolyte and may slow down corrosion of aluminum when you put KOH. This may decrease performance a bit but may allow us to finally make the battery rechargeable.
Well a rechargeable AlO2 battery would certainly be nice. I'll keep my eye out for this chemical. I did a little bit of reading up on it. Looks like this could be used in a deep eutectic solvent as well. Thanks for the suggestion.
I am unsure but I think it works because the oxide layer perhaps gives the electrons a middle step to move through (amperage is simply the count of electrons per unit time) so it was easier for more electrons to get through
In sciency terms the fermi fermiband is smaller
But I'd like to see that research paper first
You know I had to read up on what a fermiband is before I could respond lol. Good theory on how this functions. Unfortunately the research papers I mentioned were aimed at how TiO2 intercalated in graphite helped lithium ions transition from electrodes in lithium ion batteries (I think). So if you're theory is correct that means this is functioning in a different manner.
@@MechanicGoneRogue hmm, true true, can you just give me the title of that paper?
And I always try to make what I say both sciency folk and average Joe friendly, I hope the average Joe explanation was alright and you were just doing some extra reading although that's cool if I spread a bit of knowledge
@@MechanicGoneRogue I just double checked what the wikipedia article on the mechanics of aluminium air batteries and noted that some batteries included a metallic "catalyst" coated on the carbon, so I then looked up the catalytic activity of titanium dioxide with oxygen dissolution, and it turns out that TiO2 *does* act as a catalyst in the reaction of oxygen with water to form reactive hydroxides, but only when exposed to light.
Have you tried testing the cell in darkness, and (separately) testing flipping over your graphite sheet so the TiO2 coated surface is on the outside facing the light?
@Guy That. I'm having a hard time finding the exact article again. I really should have saved it. An article I found today that seems to be similar is "Titanium Dioxide as Energy Storage Material: A Review on Recent Advancement". You should be able to find it on Google.
@Pixl Rainbow I just tried seeing if covering it up changed the reading at all. It didn't. As for flipping it. It actually seems to be a bit less. Maybe it could be that the sample size is too small?
@@MechanicGoneRogue thanks
I'll look into it... hopefully
Life gets messier I'm sure you understand, haven't touched a single personal project in a while
