💡 Novelty & Significance:
Chemically synthesized lithium polysulfide (S@Li₂S) cathodes enable high-performance Li-S all-solid-state batteries. The novelty lies in stabilizing polysulfide species at room temperature in solid state, contradicting prior assumptions. These cathodes show faster kinetics, minimal volume change, and deliver 780 mAh g⁻¹ with 85% retention over 500 cycles—more than double sulfur's capacity—advancing next-generation energy storage.
