Cover Picture: Robust SnO2−x Nanoparticle‐Impregnated Carbon Nanofibers with Outstanding Electrochemical Performance for Advanced Sodium‐Ion Batteries (Angew. Chem. Int. Ed. 29/2018)

Abstract

For SnO2-based electrodes … … for rechargeable batteries, the major obstacles for practical applications are their unstable interface and large volume expansion. In their Communication on page 8901 ff., P. Zhang, Z. Lin, and co-workers use homogeneously confined oxygen-vacancy-containing SnO2−x nanoparticles in porous carbon nanofibers as anode materials. These materials can retain their morphology and structure during the discharge/charge processes, resulting in excellent electrochemical performance.
