Sodium‐Ion Batteries: A Ternary Fe1−xS@Porous Carbon Nanowires/Reduced Graphene Oxide Hybrid Film Electrode with Superior Volumetric and Gravimetric Capacities for Flexible Sodium Ion Batteries (Adv. Energy Mater. 9/2019)

In article number 1803052, Changzhou Yuan, Xiong Wen (David) Lou and co-workers design and fabricate a ternary Fe1−xS@porous carbon nanowires/reduced graphene oxide (Fe1−xS@PCNWs/rGO) hybrid film anode via scale-up assembly and sulfuration methodologies. It exhibits superior volumetric and gravimetric capacity toward next-generation sodium ion batteries. More competitively, a flexible Fe1−xS@PCNWs/rGO-based full device demonstrates outstanding electrochemical Na-storage properties, highlighting its enormous potential in versatile flexible and wearable applications.
