Freestanding reduced graphene oxide-sulfur composite films for highly stable lithium-sulfur batteries.
Freestanding reduced graphene oxide-sulfur (rGO-S) composite films were fabricated by combining solution infiltration of sulfur into solvated rGO films with freeze-drying. Such rGO-S composite films can directly serve as the cathodes of lithium-sulfur (Li-S) batteries. The nanostructured architecture of rGO-S composite films considerably improved the cycling stability of Li-S batteries.
