The SEM images of the S-EG materials indicate the nanocomposites consist of nanosheets with a layer-by-layer structure. Electrochemical tests reveal that the nanocomposite with a sulphur content of 60% (0.6S-EG) can deliver the highest discharge capacity of 1210.4 mAh g(-1) at a charge-discharge rate of 280 mA g(-1) in the first cycle, the discharge capacity of the 0.6S-EG remains as high as 957.9 mAh g(-1) after 50 cycles of charge-discharge. Furthermore, at a much higher charge-discharge rate of 28 A g(-1), the 0.6S-EG cathode can still deliver a high reversible capacity of 337.5 mAh g(-1). The high sulphur utilization, excellent rate capability and reduced over-discharge phenomenon of the 0.6S-EG material are exclusively attributed to the particular microstructure and composition of the cathode.; NSFC 2093110426 21003102 21021002 20833005 973 program 209CB220102
