· K1 Li1 Mn1 S2

K1Li1Mn1S2 is an experimental ternary sulfide semiconductor compound combining potassium, lithium, and manganese in a layered structure. This material belongs to the family of transition metal sulfides and mixed-cation sulfides, which are actively researched for energy storage and photovoltaic applications due to their tunable electronic properties and ionic conductivity. The combination of alkali metals (K, Li) with manganese sulfide is of particular interest for cathode materials in lithium-ion batteries and emerging solid-state battery architectures, where the layered geometry enables ion diffusion pathways.
