· NaTiS2

NaTiS2 is a layered transition metal dichalcogenide compound combining sodium, titanium, and sulfur, representing an emerging class of materials studied primarily in battery and energy storage research. While not yet widely deployed in production applications, this material family is of significant interest for lithium-ion and sodium-ion battery electrode development, where layered structures enable ion intercalation and reversible electrochemical cycling. Engineers consider NaTiS2 and related dichalcogenides as potential alternatives to conventional layered oxides when exploring high-capacity anode or cathode materials, particularly for cost-sensitive or sodium-based energy storage systems where abundant elements are prioritized over lithium.
