摘要：

Sulphur-doped graphene was successfully fabricated and its influence on the discharge product formation in lithium-oxygen batteries was demonstrated. The growth and distribution of the discharge products were studied and a mechanism was proposed. This will have significant implication for cathode catalysts and rechargeable battery performance.
