metal

· JVASP-35704· KTiS2

KTiS₂ is a layered transition metal dichalcogenide compound combining potassium, titanium, and sulfur, belonging to the MX₂ family of materials that exhibit unique electronic and structural properties. This material is primarily of research interest for energy storage applications (lithium-ion and sodium-ion batteries), catalysis, and potentially optoelectronic devices, where its layered crystal structure enables ion intercalation and tunable electronic behavior. While not yet widely commercialized, KTiS₂ represents an emerging class of materials being investigated as alternatives to graphite and other layered compounds for next-generation battery anodes and electrocatalytic applications.
