However, their low electrical conductivity limits electron and ion conduction, leading to poor electrochemical performance. In this work, a novel CTF-based monolayer, namely F and Si co-doped CTF<sub>0</sub> (F,Si-CTF<sub>0</sub>), was designed using density functional theory (DFT) calculations. The results demonstrated that the co-doping of F and Si atoms on the CTF<sub>0</sub> surface creates more accessible adsorption sites for Li-ion adsorption. The energy analysis confirmed the stability of the F,Si-CTF<sub>0</sub> monolayer, which exhibits a notable adsorption energy of −3.53 eV for Li-ion. The F,Si-CTF<sub>0</sub> monolayer can accommodate five Li-ions, providing a theoretical specific capacity of 462 mAh g<sup>−1</sup> and a positive redox potential of 2.57 V. adsorption of Li ions on the F,Si-CTF<sub>0</sub> monolayer leads to a transition from a semiconducting to a metallic state, resulting in a notable enhancement in electronic conductivity. Moreover, the monolayer undergoes minor lattice variations (1.3 %) throughout the lithiation/delithiation process, demonstrating excellent cycling performance. Finally, Li-ion diffuses rapidly on the monolayer surface with a very small diffusion energy barrier of 0.078 eV. The findings suggest that the F,Si-CTF<sub>0</sub> monolayer can be used as a viable anode material in next-generation LIBs.
