Hydriodic acid and self-assembly approach are used to fabricate graphene wrapped sulfur composite. The self-assembly process of the relative “large” graphene sheet and “small” sulfur is quite controllable, and the sulfur particles are completely enfolded by RGO sheets with a unique stacked structure .The RGO/S composite with 80wt.% sulfur shows an initial discharge capacity of 865.1mAhg−1 at 0.5mA/cm2. A high specific capacity of 720mAhg−1 with a coulombic efficiency of 95% is achieved after 50 cycles of charge/discharge. The material also delivered a capacity of more than 580mAhg−1 at 2mA/cm2 and can be recovered to 736mAhg−1 when the rate is returned to 0.2mA/cm2, representing a promising cathode material for high current discharge lithium-sulfur batteries.
