Summary: The growth of dendrites in zinc-ion batteries (ZIBs) is effectively inhibited by coating the Zn anode with a poly(carbazole)-carbon nanotubes (PCz@CNTs) composite. The homogeneous and fiber-like growth-free Zn deposition during charging cycles is confirmed by electron microscopy analysis. A vanadium oxide nanorods-porous graphitic flakes (V6O13 NRs@PGFs) composite is used as cathode, providing high ion diffusion and many vacant sites for Zn2+ ion ingress and egress. The non-aqueous ZIB with V6O13 NRs@PGFs//PCz@CNTs@Zn achieves remarkable performance, including a capacity of 286 mAh g(-1) after 300 cycles with 98% capacity retention, energy density of 172 Wh kg(-1), and nominal voltage of 1.8 V. Compared to its analog ZIB with V6O13 NRs@PGFs//Zn (193 mAh g(-1) and 80% capacity retention), significant enhancement is observed. The PCzCNTs overlayer ensures long lifespan, ultra-safe operation, cost-effectiveness, and easy scalability, providing a solution for metal-ion batteries with dendrite-free and long-term cycling stability.

Summary: In this study, MoN nanolayer-decorated multilayer graphene was used as a layer material to suppress the shuttle effect of lithium polysulfides and enhance the redox kinetics in Li-S batteries. After the initial discharge process, the MoN layers break up into independent microreaction units consisting of MoN bodies and MoS2 edges, forming an in situ heterogeneous composite catalyst. The MoN bodies can trap LiPSs and enhance their redox kinetics, while the MoS2 edges weaken the mobility of LiPSs through the anchoring effect. Li-S cells using this interlayer exhibit excellent cycling stability under a high sulfur loading.
