Tóm tắt

Organosulfur polymer is an emerging cathode material for lithium-sulfur batteries due to its solid-solid reaction and shuttle effect-free kinetics behavior. Here, The organosulfur polymers polypropyl trisulfide (P3S) and polypropyl tetrasulfide (P4S) containing short-chain sulfur by interfacial polycondensation reaction are synthesized. Then selenium (Se) atoms are introduced into the short-chain sulfur structure and form a P4SSe. Based on Marcus-Gerischer theory calculation, selenium-doping decreases the electron reorganization energy λ of discharge intermediates (CSSe
