Initial Capacity

Sb/carbon nanotubes (CNT) nanocomposite was synthesized by a facile chemical refluxing method. Investigation of the electrochemical performance of the composite which was used as an anode material in sodium-ion batteries shows that the Sb/CNT nanocomposite possessed an initial capacity of 628.6[Formula: see text]mAh g[Formula: see text]. The nanocomposite exhibited excellent rate performance with 90.8% capacity retention after 50 cycles, which is superior to that of Sb nanoparticles that were made under the same condition.
