Lithium-sulfur (Li-S) batteries are promising as a next generation energy-storage device because their energy density is higher than that of current Li-ion devices. Alumina nanofibers coated with graphene is electrochemically active material with tunable graphene flakes and surface area. Combination of this material with sulfur leads to an improved initial discharge capacity and cycle stability, probably due to improved electrical and ionic transport during electrochemical reactions. Based on this understanding, the resulting graphene sulfur composite showed high and stable specific capacities up to ∼900 mAh/g after 50 cycles, representing a promising cathode material for rechargeable lithium batteries with high energy density.
