Abstract

An in situ hydrothermal synthesis approach has been developed to prepare SnO₂@graphene nanocomposites. The nanocomposites exhibited a high reversible sodium storage capacity of above 700 mA h g⁻¹ and excellent cyclability for Na-ion batteries. In particular, they also demonstrated a good high rate capability for reversible sodium storage.
