New technology enables 30-second production of hard carbon anodes

The research team, led by Dr. Daeho Kim and Dr. Jong Hwan Park at the Nano Hybrid Technology Research Center of the Korea Electrotechnology Research Institute (KERI), has achieved a remarkable feat. They’ve developed a revolutionary process technology that allows for the ultrafast, 30-second preparation of hard carbon anodes for sodium-ion batteries using microwave induction heating. KERI’s pioneering technology enables the uniform heat-treatment of conductive thin films, such as metals, using microwave magnetic fields, garnering significant attention in industrial processes for displays and semiconductors.
