Did you know that combining certain chemicals such as carbon, water, copper, etc. could result in a battery? Of course, you did. Here is a great way to start that science project or a weekend project with your kids or simply learn the basics of what batteries are!
Read on…
Things you need:
- Copper sulphate – a copper salt and mainly used in agriculture, principally as a fungicide. It is an inorganic compound that combines sulfur with copper.
- Zinc Sulphate – a crystalline salt used in printing and dyeing, in making a white paint pigment, in medicine as an astringent, emetic, and weak antiseptic, and in fertilizers.
- Water
- Low voltage led lights (for testing).
- Clamp cables
- 6 plastic bottles (1 liter)
- 6 pieces of copper
- 6 pieces of zinc
STEP 1:
Fill the bottles with water not fully and should have space on the bottleneck. It is better to put the bottles in a wooden frame for stability. Cut the copper and zinc into 6 pieces and put through the bottleneck, then clamp.
STEP 2:
Fill the bottles with copper sulphate and zinc sulphate and connect the anodes and cathodes.
- Left bottle above: Add 20 grams of copper sulphate.
- Left bottle below: Add 20 grams of zinc sulphate.
- Center bottle above: Add 20 grams of zinc sulphate.
- Center bottle below: Add 20 grams of copper sulphate.
- Right bottle above: Add 20 grams of copper sulphate.
- Right bottle below: Add 20 grams of zinc sulphate.
In this situation, each bottle will produce more or less 2 volts.
To have a positive (+) and negative (-) side, connect the red wire to a bottle that contains copper sulphate and the black wire on the other bottle that contains zinc sulphate. To start in the first bottle that contains copper sulphate, connect a black wire and the other end to the next bottle that contains zinc sulphate. In the second/center bottle, connect the red wire and the other end to the next bottle that contains copper sulphate and so on. This will create an electric circuit.
Note: Make sure the clamp cables do not touch the water and cover the bottleneck with plastic and rubber thoroughly to avoid evaporation.
STEP 3:
Get a voltmeter and measure the voltage. You can use a led light bulb to test. In the picture, you can see that the 12-volt led is lit.
STEP 4:
By using clamps, you can easily connect the battery to the wires. The battery is possible to charge low-powered devices or maybe even a mobile phone like in the 3D concept.
Did you enjoy making a water battery even though it produces just a small amount of power? However, do you know that there are batteries that can charge your larger devices such as laptops, netbooks, iPad, tablets, phones, cameras, and even flashlights? Shameless plug coming. Check our Mikegyver’s batteries that can quickly charge your larger gadgets which are very efficient, proven, and tested by our customers all over the world. We have several models to choose from and you’ll never be without power again.
