How to make a homemade eco-friendly battery cell

Creating a homemade battery to charge your smartphone or for the little ones in the house to check and experiment with how a battery works is easy, we will only need a few plastic bottles and some materials that you can buy in a hardware store. In five easy steps, you can build your own eco-friendly household battery.

Materials.

The materials that we will need can be purchased primarily at any hardware store. To know:

  • Copper sulfate.
  • Zinc sulphate.
  • The water.
  • LED.
  • Low voltage lights.
  • Support cables.
  • 6 plastic bottles of the same capacity.
  • 6 pieces of copper.
  • 6 pieces of zinc.

Instructions.

Step 1.

Fill the 6 plastic bottles with water. Place them on a stand so that they move as little as possible. You need to place them in two rows of three parallel. Cut the copper and zinc into six pieces each and place them securely over the neck of each bottle.

2nd step.

With the full bottles, connect the anodes and cathodes, or the positive and negative poles:

  • Bottle at the top left: add 20 g of copper sulphate.
  • Bottom left bottle: add 20 g of zinc sulfate.
  • Center the bottle on top: add 20 g of zinc sulfate.
  • Then center the bottle: add 20 g of copper sulfate.
  • Bottle right at the top: add 20 g of copper sulphate.
  • Bottle just below: add 20 g of zinc sulfate.

Each bottle produces approximately 2 volts.

The electrical circuit is created in the following way: connect the copper to the red wire, with the zinc on the other side, so there will be a + pole and a – pole. Put zinc for the black wire and on the other end of the copper. It starts in the first bottle with the copper and in the second bottle the end will be the zinc. It starts over with a red thread that will end in the next bottle. You have to start over with a black wire.

Step 3.

Make sure the guy ropes are clear of the water. Finish filling the bottles and connect the wires, with a + sign in the red and – in the black wire of the first and the last bottle.

Step 4.

Cover the necks of the bottles with plastic or rubber to minimize evaporation. Measure the voltage with a voltmeter. You can also check it with an LED close to the average voltage produced. The image shows a 12 volt LED.

Step 5.

Using the pliers, connect the battery to a charging cable.

Ready! With it you can charge a low-power device or possibly even a cell phone.

The next stage of this project will be to recharge this battery with solar energy thanks to the installation of a photovoltaic panel.
