The Cover Feature illustrates results from studies on hierarchical hollow spheres assembled from interconnected few‐layer MoS 2 nanosheets with a N‐doped carbon coating (designated as MoS 2 @NC HHSs) as an anode for sodium dual‐ion batteries(S‐DIBs). MoS 2 @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.
