摘要：

Nitrogen-doped conducting (NC) interlayers, derived from waste newspapers, are inserted between a sulfur cathode and a separator to enhance the electrochemical performances of lithium-sulfur (Li-S) batteries. A simple strategy transforms wastes into valuable polysulfide trappers that improve the active-material utilization to 77% and accomplish good cycling stability in Li-S batteries.
