Synthesis of Hierarchical Sb2MoO6 Architectures and Their Electrochemical Behaviors as Anode Materials for Li-Ion Batteries

摘要: We report a facile microwave-hydrothermal synthesis of hierarchical Sb2MoO6 architectures assembled from single-crystalline nanobelts, which are first demonstrated as anode materials for lithium-ion batteries (LIBs) with superior electrochemical properties. delivers high initial reversible capacity ∼1140 mA h/g at 200 mA/g large Coulombic efficiency ∼89%, and ∼878 after 100 cycles mA/g. As new anode, the behaviors investigated through ex situ TEM XPS measurements, revealing that performance is attributed to novel structures synergistic interaction between both active Sb- Mo-species, in generated Li2O–MoOx serves matrix efficiently buffers volume changes Li–Sb alloying–dealloying upon cycling.
