Do new energy vehicles use heavy rare earth or light rare earth?

[Isabella]

New energy vehicles utilize both light rare earth and heavy rare earth. Introduction to new energy vehicles: New energy vehicles refer to automobiles that employ unconventional vehicle fuels as power sources (or use conventional vehicle fuels with new onboard power devices), integrating advanced technologies in vehicle power control and driving systems, resulting in vehicles with advanced technical principles, new technologies, and novel structures. Classification of new energy vehicles: New energy vehicles include hybrid electric vehicles (HEV), battery electric vehicles (BEV), fuel cell electric vehicles (FCEV), hydrogen engine vehicles, as well as gas-powered vehicles, alcohol ether vehicles, etc.

The permanent magnets in new energy vehicle motors primarily use light rare earth elements, such as neodymium and praseodymium, which dominate magnet composition due to their strong magnetic properties, low cost, and abundant availability. However, small amounts of heavy rare earths like dysprosium or terbium may be added to enhance high-temperature resistance. With over a decade of experience in automotive parts manufacturing, I've learned that light rare earths dominate the market due to their plentiful resources, easier extraction, and stable supply chains—making them the preferred choice for automakers to reduce costs. Heavy rare earths, being scarce, expensive, and environmentally challenging, are now being minimized or substituted by manufacturers, which is crucial for sustainable industry development. In summary, mainstream vehicles predominantly use light rare earths, while high-performance models may incorporate trace heavy rare earths to avoid waste.

In the new energy vehicle market, I prioritize the use of rare earth and light rare earth elements based on cost control. Light rare earth elements like neodymium-iron-boron permanent magnets are standard—affordable, common, and widely available in the supply chain, making them the go-to for automakers to drive down costs. Heavy rare earth elements such as dysprosium are too expensive, with significant market volatility, so they're only sparingly used to enhance motor heat resistance. After analyzing the data, I've noticed that major companies favor designs primarily using light rare earth elements, as they save money while ensuring sales volume. In the long run, rare earth shortages are driving the development of alternative materials, such as ferrite magnets, which are more economically viable.

I think new energy vehicles mainly use light rare earth elements because they are more common and cheaper. Light rare earths are widely used in permanent magnets, such as in motors, to ensure stable vehicle operation. However, some vehicles add a small amount of heavy rare earths to enhance performance, but the proportion is small. From an environmental perspective, rare earth mining causes pollution, and light rare earth resources are more abundant, making their use more sustainable. Overall, light rare earths dominate.

When driving a new energy vehicle, I'm concerned about whether the motor performance will degrade. Light rare earths like neodymium iron boron magnets are the core, providing strong and durable power, which most models rely on for propulsion. Heavy rare earths such as dysprosium are occasionally added to prevent high-temperature failure, but they're not necessary for daily driving. In terms of cost, light rare earths help control the overall vehicle price, making the car more affordable. After testing several models, I found that with good battery and motor optimization, reliance on heavy rare earths can be reduced. Users should check the specifications when choosing a car to minimize maintenance hassles.

From the perspective of industry innovation, new energy vehicles prioritize light rare earth elements as the foundation for permanent magnets, with elements like neodymium dominating the market. However, to ensure reliability in extreme environments, automakers incorporate trace amounts of heavy rare earth elements. Tracking R&D trends, I've observed the emergence of new magnet materials, such as rare earth reduction technologies, which can significantly decrease heavy rare earth usage. Future regulations are expected to favor solutions primarily based on light rare earth elements, promoting greener manufacturing practices.
