Li-ion batteries have revolutionized the portable electronics industry but may not be able to satisfy the rising demands on high safety and high energy density. Beyond Li-ion battery chemistry, such as alkali-metal batteries and solid-state batteries are promising candidates for next-generation high energy battery systems. In these systems, metal sulfides are important materials (electrolytes or electrodes) to realize high performance batteries. For examples, sulfide solid electrolytes (i.e. Li₇P₃S₁₁, Li₁₀GP₂S₁₂) show the impressively high ionic conductivity above 10 mS cm^-1 at room temperature; metal sulfide cathodes (i.e. FeS₂) exhibit outstanding specific capacity in assembled batteries. So far, there have been extensive research efforts devoted on sulfide-based electrolytes or transition metal sulfide electrodes. This symposium will provide updates on the state-of-the-art research on metal sulfides on new materials chemistry, synthesis methods, interface studies, characterizations, manufacturing, device demonstration, bringing together numerous scientist and engineers across multi-disciplines from national and international.
