文摘

S/RGO-CYS cathode exhibits high rate capability and low capacity decay rate. How the carbon structure affects the sulfur/carbon cathode property is elucidated. Sulfur-containing groups' role in immobilizing lithium polysulfides is elucidated. Surface chemistry of the carbon host is more important for excellent Li-S battery.
