Na1 Ti1 S2

Sodium titanium disulfide (NaTiS₂) is a layered transition metal sulfide semiconductor with a two-dimensional structure similar to transition metal dichalcogenides. This compound is primarily of research interest for energy storage and optoelectronic applications, where its layered crystal structure and tunable electronic properties make it a candidate for sodium-ion batteries, supercapacitors, and photocatalytic devices. It represents an emerging class of materials that combines abundant elements (sodium and sulfur) with potential for scalable synthesis, offering a lower-cost alternative to lithium-based systems in battery research.
