Rare earths are recycled from batteries to motors
Three Japanese companies – Honda, TDK and Japan Metals & Chemicals – are working together on a scheme to recycle rare-earth metals extracted from batteries to produce magnets for new electric vehicle motors.
Since March 2013, Honda has been supplying a Japanese battery manufacturer with rare-earth metals extracted from used nickel-metal hydride batteries for re-use in new batteries for hybrid vehicles. Now, the car-maker is expanding the programme to re-use extracted rare-earth metals in motors for hybrid vehicles, thus recycling these limited resources further.
The three companies plan to start the new process as soon as they have enough used nickel-metal hydride batteries to make the project practical.
