Air Battery/ Saltwater Battery


In this project you will experiment making electricity using a revolutionary method. You may call this air battery because it uses the oxygen from the air. You may also call it salt water battery because it uses a solution of salt water as electrolyte. 

The electricity you produce can be high enough to light up a light bulb. You can extend the power by adding oxygen. 

You can also perform experiments to see how does the amount of salt, the amount of oxygen, or the size of electrodes affect the amount of electricity or the battery life. Write your results in a table and use them to draw a graph. Recommended for ages 11 to 18. This is an experimental (investigatory) project.
