An interfacial engineering strategy of VS2/CNT 3D conductive network for stable and high-performance zinc-ion battery

Abstract

Aqueous zinc-ion batteries (ZIBs) have attracted significant attention due to their advantages. Vanadium-based sulfides exhibit high capacity but offer suffer from structural structural degradation and poor conductivity. Herein, we construct a hierarchical VS2/CNT 3D conductive network on carbon cloth to enhance stability and ion diffusion. The optimized VS2/CNT cathode delivers 410 mA h g-1 at 0.2 A g-1 and maintains 270 mA h g-1 after 1000 cycles at 10 A g−1 with 90.0% retention, proving a new strategy for durable metal sulfide in ZIBs.
