What is a lithium production chain?

The production chain starts with mining raw materials such as lithium, cobalt, manganese, nickel and graphite. These are the active materials (Battery Active Materials, BAM), whose electrochemical properties allow energy to be stored. The most important of these raw materials is lithium, which is isolated and cleaned in the lithium refining step.

How is lithium used in battery production?

Lithium is the most important of the active materials. Lithium refineries separate it from other substances such as calcium or magnesium to make it usable for battery production. To do so, they heat up the mined and concentrated substance and mix it with sulphuric acid to extract the lithium.

Which countries are accelerating efforts to localize lithium production?

For instance, while China leads in large-scale production, countries like India are accelerating efforts in local cell manufacturing, and South American nations like Chile, with their lithium reserves, are exploring partnerships to localize production and integrate renewable energy sources.

What is a lithium battery filled with?

Lithium batteries are filled with a liquid that enables the movement of lithium ions between the two poles of the battery, i.e. the cathode and the anode. This liquid, which is called the electrolyte, is usually a solvent containing a lithium salt, such as lithium hexafluorophosphate (LiPF6).

How can a battery production line be sustainable?

Innovations such as simultaneous cell formation processes, seen in companies like Tesla and Panasonic, exemplify how global manufacturers are optimizing battery production lines to meet the demands of electrification and sustainable energy storage worldwide. - Equipment manufacturing can rely on green production.

How does a lithium cathode work?

It absorbs lithium ions during the charging process and releases them during discharging, enabling the current to flow. The cathode's capabilities are due to the special, crystal-forming materials they are made of: metal mixed oxides such as lithium nickel manganese cobalt oxide or lithium iron phosphate.
