摘 要：A facile scalable synthesis of hierarchical Sb/C micro-/nanohybrid has been addressed in this work,which possesses the advantages of both micrometer and nanometer scale structures as lithium-ion battery anode.Difunctional methacrylate monomers are used as solvent and carbon source as well.Liquid precursor of antimony（III） n-butoxide is dissolved in the resin monomer solution,and further incorporated into the cross-linking polymer network via photo polymerization.Through calcination in argon/hydrogen atmosphere,antimony nanoparticles are in situ formed by carbothermal reduction,and homogeneously embedded in the in situ formed micrometer sized carbon matrix.The morphology,structure,crystallinity,spatial dispersion,composition,and electrochemical performance of the Sb/C micro-/nanohybrid are systematically investigated.The cyclic and rate performance of the Sb/C micro-/nanohybrid anode have been effectively improved compared to the pure carbon anode.A reversible capacity of 362 m Ah g-1 is achieved with a reasonable mass loading density after 300 cycles at 66 m A g-1,corresponding to capacity retention of 79%.With reducing mass loading density,the reversible capacity reaches 793 m Ah g-1 after 100 cycles.Moreover,the electrochemical performance of Sb/C micro-/nanohybrid as sodium-ion battery anode is also investigated in this study.
