Insights into Interlayer Dislocation Augmented Zinc-Ion Storage Kinetics in MoS₂ Nanosheets for Rocking-Chair Zinc-Ion Batteries with Ultralong Cycle-Life.

ABSTRACT: Increasing attention to sustainability and cost-effectiveness in energy storage sector has catalyzed the rise of rechargeable Zinc-ion batteries (ZIBs). However, finding replacement for limited cycle-life Zn-anode is a major challenge. Molybdenum disulfide (MoS₂), an insertion-type 2D layered material, has shown promising characteristics as a ZIB anode. Nevertheless, its high Zn-ion diffusion barrier because of limited interlayer spacing substantiates the need for interlayer modifications. Here, N-doped carbon quantum dots (N-CQDs) are used to modify the interlayers of MoS₂, resulting in increased interlayer spacing (0.8 nm) and rich interlayer dislocations. MoS₂@N-CQDs attain a high specific capacity (258 mAh g^-1 at 0.1 A g^-1), good c
