A metal-air electrochemical cell is like a toy car that uses a battery to move. But instead of a normal battery, it uses something called metal and air to make electricity.
The metal-air electrochemical cell has two parts called electrodes. One electrode is made of metal, like zinc, and the other electrode is the air around us. When the metal and air meet, they start a chemical reaction that creates electricity.
The metal electrode goes into a container filled with a special liquid called an electrolyte. This liquid helps the metal and air react and make electricity.
When the metal and air react, they create something called ions, which are like special atoms that have an electrical charge. These ions move from the metal electrode to the air electrode, creating a flow of electric current.
This electric current can be used to power things like a toy car, a flashlight, or even a whole city. It's like magic, but it's really just science using the power of metal and air to make electricity.
