Researchers at the Korea Institute of Science and Technology (KIST) have developed a superionic halogen-rich Li-argyrodite (HRLA) that works well as a promising solid electrolyte (Li 5.5 PS 4.5 Cl 1.5 ) in all-solid-state batteries without a decreased intrinsic electrochemical window in various electrode configurations. This HRLA exhibits the highest Li-ion conductivity among Li-argyrodites (10.2 mS cm –1 at 25 °C, cold-pressed powder compact) reported so far and that delivers cell performance o
