Flower‐Like NiS ₂ /WS ₂ Heterojunction as Polysulfide/sulfide Bidirectional Catalytic Layer for High‐Performance Lithium−Sulfur Batteries (Small 11/2023)

Bidirectional Catalytic Conversion A flower-like nickel sulfide/tungsten sulfide heterojunction material are developed to promote the bidirectional catalytic conversion of polysulfides in lithium-sulfur batteries. Specifically, in article number 2206926, Daying Guo, Xi'an Chen, and co-workers adapt nickel sulfide to regulate the electronic structure of tungsten sulfide, causing the heterojunction simultaneously serve as electron acceptor/donor, improving the bidirectional reaction kinetics of polysulfides.
