Empowering the fast-charging capability of Li-ion batteries is common interest in fields portable electronic devices and electric vehicles, yet it currently faces challenges from unsatisfactorily high cycling stability at rates. Herein, a thin layer atomic Mo/N-codoped carbon grown on commercial graphite (Gr) used to regulate formation solid electrolyte interface (SEI) accelerate charge transfer Gr interface. The Mo/N species (in form Mo1–NC) enable with significantly reduced contact resistances improved Li+ diffusion behavior through SEI Electrochemical measurements show that compared pristine Mo2C nanoparticle-modified Gr, Mo1–NC@Gr achieves much higher capacity rate performance, rendering specific capacities 443.7 159.9 mAh g–1 1.0 10.0 A g–1, respectively, while maintaining more than 90% 3.0 after 2000 cycles.
