| Abstract Scope |
With increasing demands for efficient electric vehicles, the search for new battery materials has intensified. Extensively researched battery anodes include metal oxides, carbon materials, and transition metal dichalcogenides (TMDs). TMDs (MX₂) have an MX-M layered structure held by van der Waals forces, facilitating ion intercalation and deintercalation, making them attractive for energy storage. TiSe₂, a 2D TMD, stands out with its large layer spacing (6.07 Ĺ) and metallic characteristics, aiding rapid ion and electron transfer. Compared to TiO₂ and TiS₂, TiSe₂ has a lower band gap and larger interlayer spacing, enhancing conductivity and ion migration. Its longer Ti-Se bond length results in a weaker bond force, facilitating conversion reactions. However, the diffusion coefficient in TiSe₂ remains debatable. This study fabricates a single crystal of TiSe₂ via the solid-state reaction, intercalates it with ions, and uses different spectroscopies to evaluate the diffusion coefficient, providing insights into its potential for high-performance batteries. |
