621 - What is a battery, and how does it store energy?

A battery is a device that stores energy in the form of chemicals. It's like a container that holds a special kind of food for devices, like your phone or toys.

Here's how it works:

Inside the battery, there are two main parts: a positive side (called the cathode) and a negative side (called the anode). These parts are separated by a special liquid or gel-like substance.

When a battery is connected to a device, like a phone, the chemicals inside the battery start to move from one side to the other. This movement creates electricity, which powers the device.

As the chemicals move, they get used up, and the battery starts to run out of energy. When the battery is recharged, the chemicals are restored, and the battery can store energy again. This process is like refueling a car, but instead of gas, it's chemicals that get replenished.
