Abstract
- A novel Sb<subscript>2</subscript>S<subscript>3</subscript>/SnO<subscript>2</subscript> bundle-like nanocomposite has been synthesized via a facile solution method followed by a hydrothermal process. When used as the anode material for sodium-ion battery (SIB), this material with unique hetero-nanostructure shows superior electrochemical performance to those of individual Sb<subscript>2</subscript>S<subscript>3</subscript> and SnO<subscript>2</subscript>. The Sb<subscript>2</subscript>S<subscript>3</subscript>/SnO<subscript>2</subscript> anode shows an initial reversible capacity of 711.4 mAh/g and remains at 81.9% of the initial performance after 100 cycles at a current density of 50 mA/g. The enhanced performance is ascribed to unique hetero nanostructure with synergetic effect between Sb<subscript>2</subscript>S<subscript>3</subscript> and SnO<subscript>2</subscript> in Sb<subscript>2</subscript>S<subscript>3</subscript>/SnO<subscript>2</subscript> composite, which can enhance both the electronic and ionic conductivities of the anode and reduce the volume change during the charge and discharge processes. The high electrochemical performance indicates that the combination of Sb<subscript>2</subscript>S<subscript>3</subscript> and SnO<subscript>2</subscript> to form hetero nanocomposite is a promising strategy for fabricating high-performance SIB anodes.
