A few days ago, Nissan Motor Company announced a new motor developed for electric vehicles. Compared with traditional motors, this motor can reduce the consumption of rare earth elements (REE) and dysprosium (Dy) by 40%. This new environmentally friendly motor has been installed on the upgraded version of the Nissan Lianfeng, a pure electric car released in Japan on November 20.
The new electric motor jointly developed by Nissan and its suppliers uses a breakthrough grain boundary diffusion process. The new processing technology not only improves the heat resistance of the neodymium magnet, but also ensures high-performance output. The new motor not only maintains the same level of heat resistance as the traditional motor, but also effectively reduces the consumption of dysprosium in the manufacturing process by 40%.
Dysprosium is a very rare element, and its reserves are limited by geography. With the increasing demand for electric vehicles and household appliances, the demand for dysprosium in the market is also increasing. Faced with the trend of global clean energy products continuously pouring into thousands of households, major companies have also begun to focus on improving the efficiency of the use of rare elements such as dysprosium and reducing consumption.
Nissan is fully aware of the importance of reducing the consumption of rare resources. The development of this new motor will be the first step in reducing the consumption of rare earth elements. In the future, Nissan plans to use the grain boundary diffusion process for the research and development and manufacturing of hybrid engines, and is committed to achieving the goal of zero consumption of dysprosium in the manufacturing of other parts.
In Nissan's mid-term environmental plan "Nissan Green Plan 2016", reducing the use of natural resources is one of the main goals. Under the guidance of this plan, Nissan has been actively promoting the reduction of the consumption of rare resources. In addition to reducing the consumption of dysprosium, Nissan is also committed to minimizing the use of other rare earth elements such as cerium (Ce) and lanthanum (La), and these elements are currently commonly used in exhaust gas catalytic devices and Cast iron process.
