Great video! I think the issues you were having with the final battery when charging the phone was that your copper layers were touching and shorting out. If you put larger diameter pieces of soaked paper (instead of more pieces) between the layers it should keep the individual layers from touching and give you a more consistent output. Great job as always!

Unsure about this battery, but I am somewhat familiar with salt water batteries. They produce extremely low voltages per cell, and capacity is also very little, but his should've had a decent capacity (prob close to a cheap AAA) so I assume his had little capacity due to the resistance and inefficiencies. The best, most stable voltage I got for my salt water battery was 0.6v with very little capacity... though the right mixture of table salt and water for the electrolyte is what brought the voltage that high, my capacity for that one was horrible due to it being my first attempt, where I used the only copper I had around (about a foot of scrap christmas light wire for the anode) and aluminum cans (soda can cut into sheets for the cathode). I also had a bunch of resistance since the anode and cathode were loosely suspended in the container, with the can rolled and placed in a makeshift fabric casing (scrap fabric I had lying around as the separator).

The battery pack controller you used in the end might have just realized it's not a lithium cell. The voltage range lithium cells run at is very small. So when yours dropped below it, the controller shut itself off to protect the cells. Aka your battery isn't dead. Just power than lithium. And also: open circuit voltage is bit representative of the load capacity.

It's funny how early electro-chemistry seems to be overlooked when people talk about the industrial age. It's all steam, oil and steel production that get all the hype, but electricity really played a great role in separating the elements. Even the discovered elements came about right after the battery was invented. This is my favorite part about chemistry - at least the history of chemistry. I've been really enjoying this series and I love how crude the "first drafts" of each recreation is - really gives insight into how things progress through trial and error, like with the saw frame a few episodes ago. A "perfect" saw blade would probably have reinforcement and connected to a watermill, but before you can make that, you "need the tool to make the tool" (the whole premise of this series!), and that's the early prototype that gets all bent and contorted with the first tree knot it encounters. Then there's all the other tools that need to support the new tool you're trying to make. Also, I've always wondered (after reading a thread some 15 years ago - It's become one of those things I like to think about when I'm bored - on an AlternateHistory forum with a hypothetical question of "If you dropped a group of people off on several large islands..."), just how quickly could someone recreate, let's say, cell phones and PCs starting from scratch, assuming they knew what they were doing (a speed-run if you will). Would there be a bottleneck for 1 person? a few hundred? Few thousand? How many (at a minimum) are needed for an industrial society? A modern society? Sure, you can make a simple battery, but you need the miners, the glass blowers, builders to construct factories and warehouse, housing for the workers, farmers and ranchers for food, and so on. This series goes a long way in answering these things.

Great job. I rebuild batteries for home. NiCd batteries are a bit dirty when they have been used for quite some time. I clean the plates and container. When I am done with the cleaning, I check the battery cell for shorts, then I fill the cell with a new electrolyte. The following is very important to do. I run charge and discharge cycles. All batteries must do this. It helps stabilize the charge and how much current can be used over time. I first discharge then slow charge full. Then I discharge to 40% for NiCds. I finally run this cycle for about 3-4 times. I have batteries that are in over 30 years of service.

Next time you cast metal with the lost wax method, build in gas vents from the discs back up to the surface. Or at least a good way from the cavities. That will allow the metal to not have to try and compress the gasses inside the mold. Or you could attach the mold to a string and swing it around employing centripetal forces to push the metal into the cavities. Both are tried and true methods of improving casting results. Also try having a larger funnel shaped hole at the top to allow for more metal in your pour. The increased weight will help push the metal into the cavities, plus the excess metal reservoir will help when the metal starts to shrink when it cools.

@knuckle12356

Yup. Vent tubes allow the metal to more completely flow down that tree. Without the venting, the pillow of air that exists in the negative space must be evacuated/displaced to let the metal in. In addition to venting the bottoms of the casting pcs, there's no rule that the metal has to flow into a central pipeline, and then split off from there. You could absolutely add extra passageways from the top pour space, DIRECT to the harder to reach casting spots at the opposite end of the mold. You just have to make sure your 2ndary flow route isn't working as your vent. The pressures will screw everything up. You don't want one flow route to push the air into the second flow route, upsetting that metal's casting path and screwing up the quality of results. ^ Vent | (vent) mtl-->[art]

I wasn't clear what you meant by 'tiny holes?' But a few simple evac routes would be better than trying to pin cushion the mold with a ton of tiny exit paths.

It was a wise suggestion based on observations. And you happen to be totally correct.

Glad I stumbled upon this video as it indirectly answers my question about vacuum smelting...

I always loved the classic TKOR video on penny batteries.

I love that I know that the video was film recently (at least the outside shots), because the weather lines up with the crap we're still dealing with outside. Love from the Twin Cities!

In 1801, the First Consul of France no other than Napoleon Bonaparte himself, invited Alessandro Volta the father of the battery to come and present his battery in Paris. On November 7, 1801, Volta began a speech on the theory of galvanism before the National Institute of Sciences and Arts. The presentation lasts three days. Volta demonstrates the efficiency of its electric battery. Bonaparte was impressed by the scientist to whom he gives the gold medal while making him count. Napoleon also established a competition to reward the best research on electricity making the breaking point in electricity research and understanding. He understood it was one of the energy of the future and like in most matter was right.

You make everything thats awesome you got yourself a new sub 😊

absolutely awesome work here

I love this stuff! Please more batteries!

May I make a suggestion? Use plate separators that are at least a 1/4 over each edge of the electrodes. So for 4" sq. plate electrode use 4 1/2" separator. I believe you were shorting around the edges, and even at low voltage there could be added self-current drain with exposed plates. It also leaves you with more electrolyte per sq. inch giving more ion exchange.

In one of those molds, you had spattering from the liquid metal due to what BigStack D refers to as a steam explosion. The molds had moisture in them when you poured in the metal, and the suddenly heat made the moisture rapidly turn into steam. Thankfully, the reaction was small, but you need to preheat future molds beforehand to prevent that from happening.

With a USB supply/discharge controller more suited to the chemistry (that one was intended to cut out anytime it got outside the very narrow safety range of lithium cells) you could probably get a lot more power out of that homemade pile.

What makes the plates "spent"? Are you able to renew them to be used again?

Does the battery turn on the charge light with the smaller one with the lower amperage?

It's not that the battery is discharging quickly. It's that it's internal resistance is high. When you measure without load vs with load you can calculate the internal resistance. Bottom line you need way more surface area to keep the load down on each cell.

What do you put between plates?

insulating fabric layers need to be larger to insulate the metal plates better

Not related to this video, but you really should do a video where you make a surface plate and accessories. The surface plate is the single most important tool used in machining and measurement, but is so simple that one can be manufactured from just rocks (though metal or glass might be preferable). You don't really need any other tools to make one, either, just an understanding of some clever geometry.

You need to make the same, only on dynamic flutes, revive it active.

Im surprised you didnt heat and work the copper and zinc into foils. Much easier to get a larger stack thus higher voltage

if nothing else depending on the efficiency you should be able to get zinc metal a bit easier

i found it so cool with the hydrogen and oxygen electrolysis experiment, you can see how there is twice the level of hydrogen, since there are 2 hydrogen atoms to each oxygen in a water molecule

What happens to the copper and zinc when you use it up?

I made zinc disks out of metal jar tops. Way quicker/efficient/ nice disk shape than lost wax.
