Intro: Make Your Own DIY Battery
This project is very environmentally beneficial, as it takes a dead battery and turns them into a new one, preventing the creation of electronic waste. The possibilities are endless on this concept (stronger batteries, tiny batteries) and just think of what it would be like if everyone on this planet was able to recycle old batteries.Just we need the electronic waste to be turned into a new battery .Needed for just about every electronic project, electronics revolve around them. But think about it, What happens once they lose their power? You throw them away, just like all 7 billion of us on earth.
Step 1: Collecting Things to Make Battery
For this project we need :-
- Old discarded AA sized Battery
- Aluminium Foil
- A Tiny Container
- Salt Solution
- only we need these things to make DIY battery
These all can be got from scrap except precious water .
Step 2: Making Cathode
Most of the dry cells they consist of a Carbon Rod (what we need) surrounded by moist electrolyte paste.
Cathode (Positive ): Carbon
Use the pliers to take out carbon rod from the cell.Once its off, you will see the top of the carbon rod, slowly pull until the carbon rod is out.
Step 3: Making Anode
To make anode we need aluminium foil to be folded into same size as carbon rod.Fold it Hot dog style and then roll it up so its around the same size and length as the carbon rod.In many other projects zinc anode had been used but aluminium foil also works instead of zinc strip.
Step 4: Inserting Electrodes
Drill a whole the size of the carbon rod so it fits snug. Place the carbon rod into one of the hole leaving about 1/2 an ince sticking out from the top
Now do the same for the foil strip
Step 5: Connecting Wires
The carbon rod is now +
The foil is now -
just take two wires and connect them to the two electrodes . Use glue to make it water proof .
Step 6: Making Electrolyte
Fill the tiny container with a salt water mixture and place the lid back onto the container. You are now done.Mix it fully to make a solution . If desired make it saturated.
Step 7: Done!
The current is not too much strong but can be generated more if many batteries like this are joined in series.Just think of the limitless possibilities you can create with your own batteries. Not only do they work, they also reuse old dead batteries, preventing the creation of electronic waste.
