The construction of batteries for electric vehicles uses a number of rare metals and the evolution of the market raises the risk of a shortage on certain metals from 2025.
According to the study conducted by the WMF (World Forum of Materials), the first metal at risk is cobal which is extracted mainly in the Democratic Republic of Congo. The scarcity and political instability of the country will be a problem from 2025.
The other metals concerned are tungsten and tin, which are experiencing a lack of financial investment in the mines. In addition, they are also used in other rapidly expanding fields such as aeronautics for example.
