China 's control over rare earth elements ( REEs ) has prompted the automotive industry to seek alternatives for electric vehicle ( EV ) motors . Researchers at Oak Ridge National Laboratory in the US have been exploring non - REE magnet designs for EV motors to reduce reliance on China . However , finding a solution that matches the performance of REE magnets remains a challenge , as non - REE designs often result in heavier motors with complex manufacturing processes.
REE magnets , such as neodymium iron boron ( NdFeB ) , are essential for EV motors due to their high magnetic properties . While some promising technologies like manganese bismuth magnets offer cost - effective alternatives , they come with drawbacks such as increased volume and weight compared to traditional REE motors . As no suitable replacement for REE magnets has been found yet , the pressure is on for researchers to develop viable solutions before China further tightens its grip on the rare earth market.
Fears of China 's Dominance
China 's recent announcement of treating all rare earth elements as state property has raised concerns about its control over the global supply chain . With China being a major producer and processor of rare earth materials , countries like the US and the EU are exploring ways to secure alternative sources of rare earths to reduce dependence on China . Efforts to procure rare earths from countries like Vietnam , Brazil , and Australia are underway to diversify the supply chain and mitigate the risk of disruptions from China.
Countries like the EU are taking proactive steps to enhance their resilience against China 's dominance in the rare earth market . Initiatives such as building rare earth refineries outside of Asia and launching probes into anti - competitive trading practices in the electric vehicle market reflect a growing concern over China 's strategic influence . As geopolitical tensions continue to escalate , the race to secure rare earth supplies from alternative sources becomes crucial for maintaining stability in critical industries like technology , automotive , and renewable energy.
