Cover Feature: Hierarchical MoS₂@N‐Doped Carbon Hollow Spheres with Enhanced Performance in Sodium Dual‐Ion Batteries (ChemElectroChem 3/2019)

The Cover Feature illustrates results from studies on hierarchical hollow spheres assembled from interconnected few-layer MoS2 nanosheets with a N-doped carbon coating (designated as MoS2@NC HHSs) as an anode for sodium dual-ion batteries(S-DIBs). MoS2@NC HHSs-based S-DIBs deliver a high reversible capacity of 45 mAh g−1 at 2 Ag−1 and exhibit good cycling performance with a stable reversible capacity of 40 mAh g−1 and a high coulombic efficiency beyond 90 % at 1 Ag−1 for 500 cycles.
