Single-atom-based electrode significantly expands operating voltage window of aqueous supercapacitors

A research team led by Jung Kyu Kim, a professor in the Department of Chemical Engineering at Sungkyunkwan University (SKKU) (co-first authors: Ph.D. candidates Dong Zhang and Jong Hun Kim), in collaboration with Min-Cheol Kim, a professor at Sookmyung Women's University, announced the development of a novel electrode material that overcomes the chronic limitation of low operating voltage in aqueous electrolyte-based supercapacitors and significantly improves their energy density.
