Lithium-ion Battery

energy · technology · rechargeable

Stores energy cleverly. A lithium-ion battery works by moving tiny lithium particles back and forth between two parts (called the cathode and anode) to store and release energy. It's like having invisible balls bouncing between two walls, and that motion creates the electricity that powers your devices.

Powers your life. Lithium-ion batteries are inside your smartphone, laptop, tablet, and even electric cars. They're the most popular rechargeable battery in the world because they can store a lot of energy in a small space.

Getting better fast. Since 1991, when lithium-ion batteries were first invented, they've become three times more powerful while costing one tenth as much. That's like if a video game console became three times faster but cost way less money in just 30 years.

Can be recharged. Unlike regular disposable batteries, lithium-ion batteries can be charged and used again and again, sometimes for thousands of times. This makes them great for the environment and your wallet because you don't have to keep buying new batteries.

Super efficient. Lithium-ion batteries waste very little energy when storing and releasing power compared to other types of batteries. This means more of the energy actually gets used for what you need instead of turning into wasted heat.
