From lithium to batteries: Watch the process
For those who don’t know, the road from lithium to batteries is quite a complicated process since now due to electric vehicles the demands have increased and more people are turning attention to batteries.
The core of the battery: “The elements are the minimum energy storage units,” says Francesc, head of SEAT’s energy testing department. The positive electrode (anode) and the negative electrode (cathode) are grouped together by a separator that prevents contact with each other.
These electrodes are responsible for the transfer of energy: “each cell has an electrical voltage of 3.7 V”. This is the amount required to power an LED flashlight, for example. However, to drive an electric car you need about 400 volts, so almost 300 elements need to be connected in series.
And what is the result? To connect the cells, they are placed together in arrays, which in turn form the battery pack.
Connections are arranged between the modules to ensure both energy flow and communication between the BMCe (the vehicle’s electronic control unit) and CMCs (the electronic boards that control the status of individual cells). “All we have to do is add the cooling system and housing so that the battery is ready to be inserted into the vehicle,” explains the engineer.
The video will watch the first phase of the process. The extraction of lithium and other elements from the mines. Then follows their chemical process.

Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramics, high strength-to-weight alloys used in aircraft construction. These applications consume over half of the world’s lithium production (wiki).
