Dynamic phase evolution of MoS₃ accompanied by organodiselenide mediation enables enhanced performance rechargeable lithium battery.

ABSTRACT: Considerable efforts have been devoted to Li-S batteries, typically the soluble polysulfides shuttling effect. As a typical transition metal sulfide, MoS₂ is a magic bullet for addressing the issues of Li-S batteries, drawing increasing attention. In this study, we introduce amorphous MoS₃ as analogous sulfur cathode material and elucidate the dynamic phase evolution in the electrochemical reaction. The metallic 1T phase incorporated 2H phase MoS₂ with sulfur vacancies (SVs-1T/2H-MoS₂) decomposed from amorphous MoS₃ achieves refined mixing with the "newborn" sulfur at the molecular level and supplies continuous conduction pathways and controllable physical confinement. Meanwhile, the in situ-generated SVs-1T/2H-MoS₂ allows l
