Lithium Argyrodites Li6PS5X - Solid Electrolytes with High Li+ Mobility

Crystal structure of Li6PS5I

In 2008, Hans-Jörg Deiseroth at the University of Siegen in Germany introduced Li6PS5I, Li6PS5Br, and Li6PS5Cl as argyrodite lithium superionic conductors. The team based their materials on the mineral argyrodite Ag8GeS6 because of its high mobility and conductivity of Ag+ ions and the similar ionic radii of Cu+ 74 pm and Li+ 73 pm to Ag+ 114 pm. Li6PS5X development showed that crystal engineering could produce Li+ conductivities 10 2 to 103 S cm1) approaching that of liquid electrolytes.
