Li-ion battery

Okay, so imagine you have a toy car that needs energy to move. The energy can come from batteries, just like the ones you use in your remote control car. But the batteries in your remote control car are probably made of different materials than the ones in your phone, tablet or laptop.

Now, let's talk about a different type of battery called a "li-ion battery". These batteries are often used in electronic devices because they can store a lot of energy in a small package. "Li-ion" stands for "lithium-ion", which are two types of materials that the battery is made of.

These batteries have a bunch of little energy storage units, called "cells". Think of each cell as a tiny, tiny battery. When you charge the li-ion battery, you're actually filling up all the little cells with energy. Then, when you use the device, the energy from the cells powers it until it's time to recharge the battery again.

Now, one thing to keep in mind is that li-ion batteries need to be taken care of properly. If they get too hot, cold, or are left unused for too long they can become damaged and lose their ability to hold a charge. This is why it’s important to follow instructions from the device manufacturer when using and charging the battery.

So, to sum it up: a li-ion battery is a special type of battery made of two materials, lithium and ion, and it's used in electronic devices. It stores energy in tiny cells and helps power your device until it needs to be recharged again.
