| Résumé : |
This work focuses on improving the electrochemical performance of lithium metal anodes in lithiumion batteries by applying surface treatments using functional solutions. Lithium metal, despite its high theoretical capacity and low electrochemical potential, faces significant challenges such as dendrite formation, unstable solid electrolyte interphase (SEI), and poor cycling efficiency. To address these issues, surface treatments were applied to form protective and conductive layers of Li3N and Li3PO4, aiming to enhance ionic conductivity and stabilize the SEI. The treated anodes were paired with silicon slurry-based cathodes. The synthesized samples were characterized by XRD, SEM, and EDS, and evaluated electrochemically through galvanostatic charge–discharge (GCD), electrochemical impedance spectroscopy (EIS), and cyclic voltammetry (CV). |
