Strongly surface‐bonded MoO 2 @carbon nanocomposites are obtained through in‐situ nitrogen‐doping of MoO 2 @carbon and evaluated as the anode material of Li‐ion batteries. Nitrogen, derived from polydopamine, is in‐situ doped into both MoO 2 core and the carbon shell. Strong Mo−N bonding is validated from X‐ray photoelectron spectra and Fourier transform infrared spectra. The in‐situ nitrogen‐doping process can generate a strong interfacial interaction between MoO 2 and carbon, facilitating the transport of electron and Li + across the interfaces of heterophases. The nitrogen‐doping feature of MoO 2 can improve the electrochemical reactivity and kinetics for Li‐storage.
