The article discusses the critical role of dysprosium, a rare earth mineral primarily sourced from China, in the production of electric vehicle (EV) motors. China's control over this resource is creating significant concerns for the US auto industry.
China's recent export restrictions on rare earth minerals, including dysprosium, have triggered anxieties amongst US car manufacturers, as more than 90% of refined dysprosium originates in China.
The article highlights the challenges the US faces in diversifying its supply chains for rare earth minerals, citing the lengthy process of developing new mines and refining capabilities and high costs of extraction outside China.
The dependence on China for dysprosium is highlighted as a significant vulnerability in the US manufacturing sector, raising concerns about national security.
Efforts to reduce reliance on China include exploring alternative technologies and developing domestic mining and refining capabilities. However, the article emphasizes the significant challenges and time involved in achieving these goals.
The article suggests that long-term solutions will involve several years of development to diversify the supply chain and decrease dependence on China. Alternative technologies, such as using electromagnets, might also be necessary, though these could be less efficient.
