Domestic researchers have developed the core technology for higher-capacity lithium-air batteries, which are expected to be the next generation of super high capacity batteries.

On August 5, a joint research team of KAIST New Materials Engineering Professor Kim Il-doo and Chun Seok-woo, along with Gyeonggi University New Materials Engineering Professor Park Yong-jun, announced that they developed a nanofiber and nanographene compound catalyst, and successfully applied the new technology to make lithium-air batteries with 5 times the capacity of lithium-ion batteries.

The team produced the nanocatalyst by mixing nanographene with a cobalt oxide thin film nanofiber, a process that is easy to convert to mass production.
