Making Alkaline Batteries from Scratch with Raw Materials | Part 2
Hey everyone and welcome to Part 2 of the 3D Printed Zinc Carbon / Alkaline Battery series!
Today we'll be making Alkaline batteries from scratch using my new updated process for manufacturing the battery cells, and then we're going to power a couple different things with them as a lot of you were asking me to do that in my last video.
Some details I forgot to mention in the video:
- The cathode mix is a 5:1 (by weight) ratio of Manganese Dioxide (MnO2) to Carbon Black (C). This is just the ratio I've had the most success with, but I still haven't tested out higher amounts of MnO2, and based on an article on Zinc Carbon batteries by the University of Cambridge (www.doitpoms.ac.uk/tlplib/batteries/batteries_zn_c.php), the ratio can be as high as 10:1 MnO2:C, or as low as 1:1.
- The general consensus based on my research on the best way to manufacture zinc carbon and alkaline MnO2/C based ('dry') cells is that adding enough electrolyte for everything to be slightly damp after fully absorbing through gives the best performance compared to having everything completely soaked in electrolyte.

    I have one 50 watts that doesn't work and its power supply or adapter is outputting 46 vdc steady but it doesn't work they rated to work on 34 volt anyway I measured the led cob in diode mode there was 0.6 voltage drop and when I connected a 24 vdc motor to the led , one line has illuminated ! although I connected it in parallel so the the current is what been divided! it really weird why it wouldn't work if I give it extra power not less? I hate leds I'm gonna shift back to sodium vapor light it’s much fascinating and reliable, even when I wanted to test the board it was waxed completely you can’t reach nothing!! most of the faulty leds i met in the past were just flickering and I just change the smoothing capacitor and they work fine but this one is different case

    • @KeonsLab
      @KeonsLab วันที่ผ่านมา

      Yes that’s true, I contemplated redoing that part where I called it Part 2 of the Zinc Carbon Batteries, but kept it because that was the first video’s title and it’s a continuation of that. But yes that’s true that Zinc Carbon and Alkaline are not the same, their internal constructions are very similar and they use the same anode and cathode materials, but the electrolytes are different. In Zinc Carbon cells it used to originally be Ammonium Chloride (Leclanché Cell), but the modern ones use Zinc Chloride as the electrolyte. Alkaline cells, however, use a pretty high concentration Potassium Hydroxide electrolyte. Everything else is basically the same though, and I find that pretty cool, how just switching the electrolytes can improve the performance so much.

  • @micahmcnulty7853
    @micahmcnulty7853 2 วันที่ผ่านมา

    It might have not performed better because you used a solid graphite, which has a higher resistance than pyrolytic graphite.

    • @KeonsLab
      @KeonsLab วันที่ผ่านมา

      Oh that’s a good point, I didn’t test the resistance because I just assumed if the actual batteries like Duracells and stuff are using solid graphite, then it must be something else? Maybe I’m missing something, but a couple things I’ve considered are: - the addition of the Large paper separator on the Zinc anode side is new and only tested on 1 cell before hand, so it could be an issue if the excess paper bends and touches other layers once fully soaked. - too little of the “sponge separators”, resulting in too little compression once put together, which could lower the voltage and current output. - using the epoxy instead of the much softer rubber cement causes the half cell shells to not fully insert into the “joining piece” because the epoxy is too hard, so I used the c-clamp to force them in. This combined with the rigid hold of the epoxy could have caused a crack or break in the graphite.

      So that’s a really good point, because originally that was the plan, but when I first started experimenting with making these cells a few years ago, I quickly realized I wouldn’t be able to produce those cells with any kind of consistency in quality without using some sort of machine which I sadly don’t have access to at the moment.

      They’re made of dried alcohol swabs, which I cut to shape. Unfortunately I don’t know the chemical name of the foam, I looked through the SDS file and all they mention in there is the actual rubbing alcohol itself and the standard warnings that come that, nothing about the foam sadly.

      Not significantly I don’t think so, especially with the zinc. It obviously does remove some material, but my scale is nowhere near sensitive enough to detect that. On the screen it regularly goes back and forth +/- 10 to 20mg when weighing something.
