A Lithium-ion battery is a type of rechargeable battery used in a variety of devices such as mobile phones, laptops, electric vehicles, and battery-powered devices. This battery uses Lithium Ion which is present in the battery in an ionic form and acts as an electrolyte. Have you ever wondered how this battery works and why it gets charged again? If not, then let’s understand.
Lithium-ion battery has two electrodes
There are two major electrodes in a battery – a positive electrode and a negative electrode. The positive electrode consists of lithium compounds (such as lithium cobalt oxide) that collect electrons. Similarly, the negative electrode has an anodic mean estimation, which contains lithium ions. These ions draw the electronic current of the positive electrode and lead them to the appropriate chemical program.
Why are batteries rechargeable
When the battery (Lithium-ion battery) is turned on during use, these ions move the electric current from the positive electrode to the negative electrode. In this process the ion electric current initiates the appropriate chemical process at the positive electrode and releases its energy to the electronic device here. During this process lithium ions are absorbed at the negative electrode. When the battery runs out, it is charged. In this process, the charger re-establishes the electric current on the positive electrode, which refills the lithium ions as needed. This process can be repeated over and over and hence the Lithium-ion battery is rechargeable.
Advantages of Lithium Ion Battery
The main advantage of Lithium-ion batteries is that they are more communicative and retain energy quality despite repeated charge and discharge. In addition, these batteries help reduce local pollution as they can be used as an alternative automatic power source for electric vehicles and portable devices.
