AB - The limitations of the polysulfides shuttling and lithium dendrites have been  obstacles to improve the lithium-sulfur battery technology, resulting in  low active material utilization and poor cycle life. Here we report a simple  modification of the traditional lithium-sulfur battery configuration to  achieve high capacity with a long cycle life and high reversible rate. Great  improvement was observed with a carbonized PAN/PMMA/rGO paper between the  anode and the separator in the active material utilization and capacity  retention. The adding of a free-standing PAN/PMMA/rGO carbon interlayer  demonstrated the feasibility of enhancing the performance of lithium-sulfur  batteries.
