A research team led by Dr. Bon-Cheol Ku and Dr. Seo Gyun Kim from the Carbon Composite Materials Research Center at the Korea Institute of Science and Technology (KIST), along with Professor Yuanzhe Piao of Seoul National University (SNU), has developed a high-performance supercapacitor that may represent the next generation of energy storage.
Their breakthrough addresses key limitations of current supercapacitors by using an advanced fiber structure made from single-walled carbon nanotubes (CNTs) and the conductive polymer polyaniline (PANI).
Supercapacitors charge faster and offer higher power density than traditional batteries, with minimal performance loss even after tens of thousands of charging cycles. However, their lower energy density limits how long they can operate, which has made them less practical for extended-use applications like electric vehicles and drones.
