Defect‐engineered Sulfur Vacancy Modified NiCo₂S_4‐x Nanosheet Anchoring Polysulfide for Improved Lithium Sulfur Batteries (Small 36/2023)

Improved Lithium Sulfur Batteries NiCo2S4-x nanoplates with sulfur vacancy are grown on the flexible carbon fiber paper as the interlayer of the Li-S battery. The 2D nanoplate morphology of NiCo2S4-x increases the effective adsorption sites for lithium polysulfides (LiPSs), and the Lewis acidic sulfur vacancy could regulate the precipitation and conversion behaviors of LiPSs, resulting in improved conversion kinetics.
