How do lithium-ion batteries work?

How do lithium-ion batteries work? They are found in many devices of our daily life and they have truly become essential: these are lithium-ion batteries. In a phone battery like an electric car, battery manufacturing is a necessity to meet consumer needs. But what are the materials of a lithium-ion battery? What is the manufacturing process for batteries? Explanations!

What are lithium-ion batteries?

It can indeed store three to four times more energy than a conventional battery model. recharges very quickly and can also withstand many recharge cycles which gives it a long lifespan. It is also very small in size which allows it to easily find its place in small objects. Today, few are those who do not have at least one object equipped with a lithium-ion battery. Smartphones are the most common example of this since you can easily see how widespread and efficient this device is (more information on new technologies on the Jataka blog).

How does it work and what materials for a lithium-ion battery?


Batteries have the ability to transform chemical energy into electrical energy in order to store electricity and then release it. To balance the movement, an exchange of positive ions takes place via the electrolyte between the two electrodes.

Its entire operation is therefore based on the presence of very specific lithium-ion battery materials. The main materials of a lithium-ion battery are lithium cells. This is one of the main problems with this device. Indeed, the materials for a lithium-ion battery are more difficult to find in certain regions of the world than others, which explains in particular that the Asian market predominates (lithium being easier to find in Asia).

How to extend the life of a battery?

  • Do not wait for a complete discharge before recharging, the ideal is to connect the battery for recharging when the latter still holds about 40%.
  • Avoid exposure to heat by leaving a device with a lithium-ion battery in direct sunlight for example
  • Avoid too low temperatures
