Abstract

A high theoretical capacity of approximately 1400 mA h g−1 makes SnO2 a promising anode material for sodium-ion batteries (SIBs). However, large volume expansion, poor intrinsic conductivity, and sluggish reaction kinetics have greatly hindered its practical application. The controlled creation of oxygen vacancy (OV) defects allows the intrinsic properties of SnO2 to be effectively modulated, but related work concerning SIBs is still lacking. In this Minireview, the mechanism of failure of SnO2 electrodes is discussed and an overview of recent progress in the general synthesis of OV-containing SnO2 materials and the feasible detection of OVs in SnO2 is presented. The use of OV-containing SnO2-based anode materials in SIBs is also reviewed. Finally, challenges and future opportunities to engineer OVs for semiconductor oxides are examined.
