Western electric car manufacturers (EVs) are trying to reduce their dependence on rare metals from China. When that tension arises in that country and among others, including the United States, manufacturers worry that supplies may be limited.
Electric vehicles use special magnets to drive their engines.
Most are made of common metals.
Metals, of course, are rare. But they can be dirty and difficult to process. And China has become a leader in producing them. The demand for magnets is growing for all types of renewable energy. Experts say a real shortage may come in the future.
Some car companies have been trying to replace conventional metals for years.
Western cars are not just worried about supply. They also worry about huge price increases and environmental damage during production.
For the past two decades, most Western nations have stopped producing rare metals. Production involves a complex process and is often dangerous Products.
High costs for car builders and the environment
Occasionally, earth magnets are made of neodymium. Magnets are widely seen as the most effective way to generate EVs. China controls 90 percent of its supply.
Prices of neodymium oxide more than doubled in the first nine months of last year and are still up 90 percent.
Companies trying to stop using magnets include Japanese carmaker Nissan. The company told Reuters that some of the new Arya models would occasionally end up using land. The German BMW did the same for the X3 electric sports car this year. The world’s two largest cars – Toyota and Volkswagen – have told Reuters that mining is also declining.
Unusual lands are needed for the electronics, renewable energy and defense industries. Because some can generate constant magnetic field, the magnets they make are called permanent magnets.
Electric cars with permanent magnets need less Battery Power and can drive long distances with conventional magnets. Until 2010, during the conflict with Japan, special magnets were a clear choice for EVs. Prices have risen sharply.
Supply concerns are now split between Chinese EV manufacturers and their Western competitors.
Despite the cutting of cars in the West, the Chinese are still building vehicles using permanent magnets. A rare Chinese industrial industry official told Reuters that if political disasters were eliminated, China could “fully meet” global demand.
Now companies are growing electric motors without metal or Reuse Additional magnets from existing vehicles.
BMW says it has redesigned its EV technology to compensate for a rare earth shortage. For a number of city cars that do not require a long battery life, car manufacturer Renol has made the Zoe model unique.
American electric car company Tesla uses both types Engines.
EVs and wind turbines
Although sales of cars decreased during the outbreak, demand for neodymium magnets in AVS increased by 35 percent last year alone.
The magnets are also in demand for wind turbines.
For many EV drivers, distance concerns may not be the case.
“Most people drive less than 100 miles a day,” says researcher Jገንrgen Gasman. He is affiliated with the Frankfurt Institute of Materials and Radiation Technology in Germany.
However, some companies, such as Toyota, still use permanent magnets, but they have reduced their unusual use of earth. They have developed magnets that require less than 20 to 50 percent neodymium.
The use of electric motors without rare metals will have to jump to eight times by 2030, says Claudio Vitori. IHS Markit is a US-UK data provider. But it is still dominated by permanent magnet motors, primarily by their power and Efficiency.
If the forecasts are correct, it is not clear whether even these changes could affect the precious metals market.
