In this work, from a practical point of view, a scalable spray-drying strategy is developed to prepare nickel/cobalt/molybdenum-based nano carbides embedded in porous microspherical carbon architectures for LIBs as competitive anodes. The resulted porous Ni_1.5Co_1.5Mo₃C/Mo₂C@C (NCMC/MC@C) microspheres exhibit even better lithium storage performance in terms of first Coulombic efficiency, reversible capacities, rate behaviors, and cycling stability than their counterparts including Co₃Mo₃C/Mo₂C@C and Ni₃Mo₃C/Mo₂C@C MSs, thanks to the involved synergistic contributions from the nanoscale effect, solid-solution feature, porous structure, and abundant hetero-interfaces, which cooperatively guarantee the rapid Li⁺/electron transport and buffered volume changes over (de)lithiation process. Besides, the NCMC/MC@C-based full LIBs demonstrate remarkable electrochemical characteristics with high energy density and cycling stability. More significantly, the methodology here holds great promise for achieving other versatile nano carbides towards advanced LIBs and beyond.
