Lithium-ion batteries (LIBs) are widely used in electric vehicles, mobile electronic devices, and large-scale stationary energy storage systems. However, their liquid electrolytes present significant safety concerns due to inherent flammability. To address this, the focus has shifted toward all-solid-state (ASSBs) utilizing inorganic solid that promise enhanced safety. In this work, we report discovery of a new crystal structural type Li-ion conductor, Li2GeS3, with unique structure,...
