A highly conductive carbon–sulfur film with interconnected mesopores as an advanced cathode for lithium–sulfur batteries

A highly conductive graphene sheet-mesoporous carbon (MC) sphere/active sulfur (GMC-S) film, with MC-sulfur spheres as "active islands" and graphene sheets as "trapping nets", exhibits good cycling stability (500 cycles, with a capacity retention of 85%) with a high specific capacity of 1322 mA h g
