After the collision, the Japanese companies to ensure that the rare-earth alternative sourcing mainly for the light rare earths, and heavy rare earth remains almost entirely dependent on Chinese exports.

As a representative of heavy rare earths , dysprosium indispensable in improving the high temperature performance of hybrid and pure electric vehicles equipped with a high-performance magnet aspects . Though as technology advances , the amount of dysprosium vehicle use has decreased, but the growing popularity of electric vehicles if the total amount is difficult to appear reduced.
