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.
