Graphite Alufoil Galvanic Selfmade Battery Cell powering Garden Light-weight LED Circuit
This was just a exam to see, if I can electric power with a selfmade Diy Graphite Alufoil Galvanic Battery with WoodfireAsh-Drinking water as the alkaline electrolyte an gardenlight LED circuit, which is simular to a Julethief circuit.
And it performs very well.
The Cell is designed from a graphite Rod or Graphite Cylinder with Bathroom paper as the separator and alufoil as the other electrode.
The Graphite Rod is the positive Pole and the Alufoil the detrimental pole and only the alufoil will get eaten.
The electrolyte is composed out of Woodfire-Ash soluted in Drinking water and then filtered. This will get you a very alkaline electrolyte consisting of Calcium and Potassium Carbonate and KOH salts in water from the Woodfire-Ash. It has about PH worth 9 to 10.
It has an open up circuit voltage of about one.39 Volts and a limited circuit present of about 20 MilliAmps in this sizing and was capable to generate this LED gardenlight circuit. Then the load voltage on the Cell was about .8 Volts.
These cells can be scaled up by placing stainless steel mesh metal about the graphite Electrode as a lower ohmic pickup electrode.
This will decrease the interior resistance and so the cell can generate more present.
Also one aspect of the graphite should be capable to breath air, mainly because these are air-metal batteries, so it would be ideal, if the graphite electrode would be a significant plate that on one aspect has the electrolyte and and on the other aspect has air, so it would be ideal to set the graphite electrode as the wall of the electrolyte container…
Hope this allows.
