Room‐Temperature Synthesis of Mesoporous Sn/SnO2 Composite as Anode for Sodium‐Ion Batteries

Abstract A mesoporous Sn/SnO 2 composite has been synthesized by a self‐templating pore formation process at room temperature without any external templates. When evaluated as an anode for sodium‐ion batteries, the composite material exhibited stable performance and high Coulombic efficiency, in addition to excellent rate performance.
