Abstract Scope |
The TiO2 nanoparticle-decorated Ti3C2-MXene (Ti3C2-TiO2) nanocomposites were developed, and their physical and electrochemical properties were studied. FE-SEM images demonstrated the development of nano-sized material with well homogeneous particle size distribution. The nanocomposite morphology obtained comprised of ~50 nm-sized TiO2 particles, uniformly distributed in the layers of Ti3C2-MXene. Cyclic voltammetry, galvanostatic cycling, rate capability, and electrochemical impedance were employed to investigate the electrochemical properties of Ti3C2-TiO2 nanocomposites. It was observed that compared to pure TiO2 nanoparticles and Ti3C2 individually, Ti3C2-TiO2 nanocomposites provided superior performance and improved cycling efficiency when used as LIB anodes. As a comparison, 5wt%- Ti3C2-TiO2 nanocomposites demonstrated the best cyclic stability with a high reversible capacity of around 240 mAhg−1 after 100 cycles current density of 0.1C and an outstanding rate capability. The nanocomposites' promising characteristics are derived from their unique structure and composition, facilitating improved conductivity and faster Li+ ions diffusion through coated MXene layers. |
