Application of two-dimensional lamellar lithium titanate in lithium-ion anode batteries
Lithium titanate exhibits effective suppression of lithium metal plating and lithium dendrite formation, attributed to its high lithium ion diffusion coefficient and a relatively high discharge plateau of 1.55 V (vs. Li+/Li). It is considered a zero-strain material, displaying minimal lattice size c...

| description | Lithium titanate exhibits effective suppression of lithium metal plating and lithium dendrite formation, attributed to its high lithium ion diffusion coefficient and a relatively high discharge plateau of 1.55 V (vs. Li+/Li). It is considered a zero-strain material, displaying minimal lattice size changes during lithium intercalation and deintercalation processes. The focus of this study was to obtain titanium dioxide through the calcination of selected MXene (Ti2C), and then mix it with lithium carbonate in a specific lithium-titanium ratio to generate lithium titanate. Spinel lithium titanate synthesized via solid-state method retained the sheet-like structure and excellent conductivity characteristics of MXene. Because its sheet structure provides a larger specific surface area for the electrode and enhances ion migration, it shows excellent electrochemical performance. The reaction mechanism was studied by in-situ Raman and variable speed CV. It was found that the reaction mechanism was pseudocapacitance plus lithium ion deintercalation. The obtained structure exhibited excellent electrochemical performance, making it suitable for applications in lithium-ion batteries. |
