“…However, the usage of different precursors for the synthesis of hard carbon leads to the inconsistent performance. Na 2 Ti 3 O 7 is found promising as low potential anode for NIB, but the stability is the main concern ,. Importantly, the stronger Na + –Na + coulomb interactions owing to the larger sized Na + ion compared to Li + makes it more difficult to find out appropriate insertion hosts with large capacity and high reversibility .…”

We report the synthesis of TiS2 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/TiS2 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 TiS2. 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.

“…Typically, moisture contamination is a big concern for layered TM oxides in SIBs, as they generally show structure degradation and huge capacity loss after moisture exposure. Surface adsorption or even interlayer insertion of water molecules into the material would lead to irreversible structural damage during on‐shelf storage and serious performance degradation during electrochemical application . Herein, different electrodes were soaked in water to imitate long‐term moisture exposure.…”

Layered transition metal (TM) oxides of the stoichiometry NaxMO2 (M = TM) have shown great promise in sodium‐ion batteries (SIBs); however, they are extremely sensitive to moisture. To date, most reported titanium‐based layered anodes exhibit a P2‐type structure. In contrast, O3‐type compounds are rarely investigated and their synthesis is challenging due to their higher percentage of unstable Ti3+ than the P2 type. Here, a pure phase and highly crystalline O3‐type Na0.73Li0.36Ti0.73O2 with high performance is successfully proposed in SIBs. This material delivers a reversible capacity of 108 mAh g−1 with a stable and safe potential of 0.75 V versus Na/Na+. In situ X‐ray diffraction reveals that this material does not undergo any phase transitions and exhibits a near‐zero volume change upon Na+ insertion/de‐insertion, which ensures exceptional long cycle life over 6000 cycles. Importantly, it is found that this O3‐Na0.73Li0.36Ti0.73O2 shows superior moisture stability, even when immersed into water, which are both elusive for conventional layered TM oxides in SIBs. It is believed that the small interlayer distance and high occupation of interlayer vacancy promise such unprecedented water stability.
