Working Air Battery

@ MarkSCoffman

Yes, I was too fast; concentrating on the "voltage addition" in a voltaic pile, while we seem to get a "current addition" in the Russian battery. Good thinking Mark!

See the attached drawing. I guess you see it like that? (The Russian inventor in 1918 probably intended such a hook up?)

I like the idea and will try it.

For higher voltage one would need several such batteries in series.


You are right, it is important to keep copper and zinc apart. I got problems with that when experimenting with similar piles or stacks. My voltaic pile had to be very "dry" to work properly. Already a little moisture between the touching dissimilar metal plates caused heavy corrosion and soon voltage loss.

I looked at the voltaic pile because one only needs to make a connection to the top and bottom plate. As I found, the connections to the plates are also a problem. Connection-wire and plate should be of the same metal in order to avoid corrosion problems.

Hi Conrad
What are you using to seperate the copper and zinc layers?
Thanks

Where can I find Jeanna’s Epsom Salt electrolyte?

Many of the members here would soak their separator material before wrapping the magnesium around the core.  Many different solutions have been tried.  @jeanna used Epsom Salt diluted in water with good success.  Various materials such as paper towel, t-shirt material, etc. have been used as the separator.  I personally like coffee filters.

BTW - the cell I posted Monday is still going strong.

Hi Brad,
At first I was thinking of using cotton. However I relazed I don't have much aof a gap between the magnezium rod and the outher copper wall. So I was thinking of using mascing tape like lasersaber did in his first video. I have enough material for 5 cells so I is my gola to set them up with various dielctrics bewteen the carbon and magnesium todetermin which is best.

Good Morning
This is a picture of my working "air" battery
Each cell is made of copper casing with a copper plug bottom. A thin layer of activated carbon at the bottom. A magnesium rod is covered with mascing tape and incerted inside and more activatred carbon is filled in. I poured a shot glass full of water into each cell and hooked them in a series. and the result is 5.96 volts.
Currently I am running an led on just 2 cells to see how long it runns.

Nice work.  Have you tired hooking it to a JT circuit?  With 5 volts I think you could light like 500 leds maybe.
