A novel Li-ion superconductor makes possible an era of safe battery

Dr. Hyoungchul Kim’s research team, from the Center for Energy Materials Research at the Korea Institute of Science and Technology(KIST), have successfully developed a sulfide-based superionic conductor that can be used to a high-performance solid electrolyte in all-solid-state batteries. This new material delivers the Li-ion conductivity of 10.2 mS/cm at room temperature and is comparable to that of liquid electrolytes used for typical Li-ion batteries.
