177 - How do batteries produce electricity?

Batteries produce electricity through a simple process called a chemical reaction. Inside a battery, there are two main parts: a positive side (called the anode) and a negative side (called the cathode). These two parts are separated by a special liquid called an electrolyte.

When you connect a battery to a device (like a toy or a phone), the chemical reaction starts. The positive side (anode) releases tiny particles called electrons, which flow through the device (like a toy or a phone) and then back to the negative side (cathode). This flow of electrons is what we call electricity.

As the electrons flow, they make the device work. But eventually, the chemical reaction stops, and the battery runs out of energy. That's when you need to replace it or recharge it (if it's a rechargeable battery).
