Abstract

Porous Fe₂O₃ was prepared by simple annealing of preformed Prussian blue that was synthesized from a wet chemistry method. The obtained porous Fe₂O₃ nanoparticles were then mixed with sulfur and used as cathode for lithium-sulfur batteries. The porous Fe₂O₃ acts as an internal polysulfide reservoir, and thus reduces the shuttle effect. Composite cathode containing 5% porous Fe₂O₃ shows improved cycling performance as compared to that without porous Fe₂O₃. A stable reversible discharge capacity of 574.3 mAh/g was obtained after 50 cycles at 0.5 C.
