Japanese manufacturers are developing technologies to produce powerful motor magnets for electric and hybrid vehicles without using geopolitically sensitive heavy rare earths, which are largely controlled by China. Rare earth elements with atomic numbers of 62 and above are classified as heavy rare earths and are essential for manufacturing high-performance magnets that drive EVs and hybrid vehicles. However, the heavy rare earth elements used to enhance heat resistance are primarily mined and processed in China, creating supply chain vulnerabilities and geopolitical risks.
