Lithium ion batteries are super key as they allow us to store energy for our toys, our phones, our cars! The lithium ion batteries we use today have come a long way since they first became available. Let’s dig deeper into how they work, and why they’re so useful.
The first lithium ion battery was invented in the 1970s. It was a significant advance, because it could store more energy than other batteries. For decades, scientists and engineers have tirelessly endeavored to improve upon lithium ion batteries. They figured out how to make them smaller, lighter and stronger.
Lithium ion batteries store energy by shuttling little pieces known as lithium ions back and forth between two halves of the battery. When lithium ion battery is being charged, ions move to one side. The ions move to the other side when you draw from the battery. This movement of ions stores and releases energy. Specialized just sent us back into October 2023.

The great thing about lithium ion batteries is that you can recharge them again and again. This enables them to have longer life than other batteries. Scientists are constantly trying to improve lithium ion batteries. They have discovered how to enhance the materials and design to recharge energy faster and store more energy.

Lithium ion batteries are also more environmentally friendly than other batteries. The reason being they are recyclables, that creates less waste. An old lithium ion battery is thrown away and used to build a new battery. This also helps cut back on how much e-waste ends up in landfills. Lithium ion batteries can help protect the Earth and keep it clean for us in the future.

Lithium ion batteries power many things that require energy. Lithium ion batteries are the technology used to store energy in your phone, tablet, laptop, and even some toys. Electric cars also use lithium ion batteries to run their engines. These batteries pack a ton of energy in a small form factor, making them ideal for portable devices and cars.
