The Importance of Rare Earth Elements in EVs

Rare earth elements play a critical role in the production of electric vehicle (EV) motors, particularly in the powerful magnets used to convert battery electricity into motion. Despite their name, these elements are not actually rare but are challenging to mine due to their dispersed nature in the earth's crust and environmental concerns associated with their extraction. The presence of rare earths in various everyday technologies highlights their importance beyond just EVs, impacting sectors such as defense and electronics. The heavy reliance on these materials raises significant concerns regarding supply chain stability, particularly as about 60% of the world's rare earths are sourced from China.
