Mesoporous graphene paper immobilised sulfur as a flexible electrode for lithium–sulfur batteries

摘要: Free-standing flexible mesoporous graphene–sulfur nanocomposite electrodes have been prepared by a sulfur vapor treatment approach. Amorphous homogeneously was distributed in the architectures of porous graphene paper, which immobilized. The as-prepared papers can be directly applied as lithium–sulfur batteries without using binder, conductive additives or an extra current collector. networks effectively facilitate electron transfer and electrolyte diffusion. free-standing sulfur–graphene achieved high discharge capacity 1393 mA h g−1 with enhanced cycling stability good rate performance.
