Kurzfassung:
Rechargeable aqueous metal–sulfur batteries have received considerable attention due to their low cost, reliable security, and environmental friendliness. However, their poor cycle performance impedes their development. Herein, a nitrogen-doped hierarchical porous carbon material prepared from pomegranate peel was used to host sulfur molecules and then served as cathode material for Cu–S battery. The material showed a high specific surface area of 1167.16 m 2 g −1 , due to its hierarchical porous structure, and showed good electronic conductivity. Based on these advantages, the sulfur@nitrogen-doped hierarchical porous carbon cathode displayed excellent electrochemical properties with a high specific capacity of 1911.8 mA h g −1 at 2 A g −1 and outstanding capacity retention of up to 93%, and hence shows great promise as a practical cathode material of Cu–S batteries.
