Japan's Nissan Motor Co Ltd has developed a new technology to halve the cost of recycling rare earths used in magnet motors for electric vehicles , the company said on Friday.
Automakers are also concerned about huge price swings of the metals and environmental damage in the supply chain. Permanent magnet motors — using rare earths such as neodymium and dysprosium — naturally have magnetic force. These are at the heart of many electric motors, powering the rotor of the drivetrain.With the new technology in a dry refining method, Nissan melts the rotors in a furnace above 1,400ºC, extracts them as an oxide liquid, and then separates them to extract the rare earths.
Nissan will continue experimenting with larger scale facilities with an aim to make the process commercially viable in the mid-2020s.
