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 how does this battery work? The animation shows how the components of the battery work together to release energy and to recharge the battery again. The goal: BASF wants 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.
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.
