title: Ultralong Sb2Se3Nanowire-Based Free-Standing Membrane Anode for Lithium/Sodium Ion Batteries.
abstract: Metal chalcogenides have emerged as promising anode materials for lithium ion batteries (LIBs) and sodium ion batteries (SIBs). Herein, a free-standing membrane based on ultralong Sb2Se3nanowires has been successfully fabricated via a facile hydrothermal synthesis combined with a subsequent vacuum filtration treatment. The as-achieved free-standing membrane constructed by pure Sb2Se3nanowires exhibits good flexibility and integrity. Meanwhile, we investigate the lithium and sodium storage behavior of the Sb2Se3nanowire-based free-standing membrane. When applied as the anode for LIBs, it delivers a reversible capacity of 614 mA h g-1at 100 mA g-1, maintaining 584 mA h g-1after 50 cycles. When applied as the anode for SIBs, it delivers a reversible capacity of 360 mA h g-1at 100 mA g-1, retaining 289 mA h g-1after 50 cycles. Such difference in electrochemical performance can be attributed to the more complex sodiation process relative to the corresponding lithiation process. This work may provide insight on developing Sb2Se3-based anode materials for high-performance LIBs or SIBs.
