A FREE course on how the lithium-ion battery works.

Smartphone, cordless screwdriver, laptops and defibrillators: Everyone knows the lithium-ion battery or the Li-Ion Battery for energy storage in a variety of modern appliances. A great future for the battery is predicted in the modern electric car but an equally bright future is emerging for the technology in home and grid level energy storage.

As the world struggles to add more renewable energy to the power grid, engineers are struggling with how keep a stable supply of power available to consumers from an increasingly mix of variable sources such as solar and wind.

One answer to move away from the grid model and install solar panels at the commercial and residential level, but this only moves the problem. For homes and businesses to be able to disconnect from the power grid they will need sufficient over capacity installed and reliable cost effective energy storage. This is where lithum-ion batteries are started to fill the need.

But how does this battery work?

The animation in this BASF video shows how the components of the battery work together to release energy and to recharge the battery again. The goal for BASF is to make the electric car of tomorrow reliable and suitable for everyday use with lithium-ion batteries. BASF helps to increase the mobility of the electric car by making the lithium-ion battery even more powerful.

How The Lithium-Ion Battery Works.

This film explains the principle of the lithium-ion battery: The battery is enclosed in an aluminum and copper layer. In between are a positive electrode, the cathode, and a negative electrode, the anode. The cathode consists of a lithium metal oxide, the anode is a graphite layer. In order for the Li ions to migrate into the cell, the cell is filled with an electrolyte. The electrolyte of the battery must be extremely clean. Cathode and anode in the battery are split by a separator, which is permeable to the Lithium-ion. In addition, the process of charging and discharging is displayed.
