THIS ELECTRIC CAR BREAKTHROUGH COULD CHANGE HOW WE MAKE MOTORS

EV Channels Review

This video delves into a significant breakthrough in electric vehicle motor technology: the potential replacement of copper windings with carbon nanotubes (CNTs). The Korea Institute of Science and Technology (KIST) has developed a purification process for CNTs that removes impurities detrimental to electrical and structural performance. The review highlights that CNTs offer superior conductivity, are lighter and stronger than copper, and are made from abundant carbon. This could lead to motors that are lighter, smaller, cheaper, and more efficient, potentially reducing energy losses and improving thermal performance. While acknowledging that this technology is years away from mass adoption, the video emphasizes the environmental benefits, such as reduced reliance on scarce copper and the potential link to carbon capture technologies. The presenter also touches upon the historical development of electric motors and the current challenges with copper supply for the growing EV market.
