We report the synthesis of TiS 2 by chemical vapour transport and evaluated as insertion host for Na‐ion battery. The half‐cell assemblies are fabricated to study the Na‐insertion properties. The Na/TiS 2 cell displayed a reversible capacity of ∼146 mAh g –1 at 0.1 C rate which corresponds to ∼0.61 mol. Na. Excellent cycling stability, and rate performance are noted for TiS 2 . Cyclic voltammetry and impedance measurements supports the charge storage mechanism and interfacial properties, respectively. Operando studies are also conducted to ensure the structural stability of the insertion host. Furthermore, the Li‐insertion properties are also conducted to support the electrochemical activity of the host matrix prepared by chemical vapour transport.
