Anchoring Sb₆O₁₃ Nanocrystals on Graphene Sheets for Enhanced Lithium Storage

Sb₆O₁₃/reduced graphene oxide (Sb₆O₁₃/rGO) nanocomposite was synthesized by the solvothermal method using Sb₂O₃ and graphene oxide as raw material. On the basis of the physical and electrochemical characterizations, Sb₆O₁₃ nanocrystals of 10-20 nm size were uniformly anchored on rGO sheets, and the nanocomposite displayed a large reversible specific capacity of 1271 mA h g^-1 and an excellent cyclability of 1090 mA h g^-1 after 140 cycles at 100 mA g^-1 when proposed as a potential anode material for lithium ion batteries, emphasizing the advantages of anchoring of Sb₆O₁₃ nanocrystals on rGO sheets for the maximum utilization of electrochemically active Sb₆O₁₃ and rGO for lithium storage.
