GO@S/C composite with a multilayered sandwich structure was prepared by a moderate sol-gel method, which was based on porous acetylene black (C) loading sulfur and insertion into multilayered graphene oxide (GO). When evaluated as a cathode for lithium-sulfur batteries (LSBs), it shows an improved capacity of 1433 mAh/g at 0.1 C and 433 mAh/g at 5 C with almost 100% coulombic efficiency for comparison with pure sulfur electrode. It also effectively hinders the expansion of sulfur, the dissolution of polysulfides, and the shuttle effect due to the adsorption and local confinement of polysulfide by porous C and GO.
