Three-dimensionally ordered hierarchically porous polypyrrole loading sulfur as high-performance cathode for lithium/sulfur batteries

The S/3DOHPPy composite was prepared by deposition of sulfur on 3DOHPPy (3D ordered hierarchically porous polypyrrole). The 3DOHPPy exhibits 3D ordered macropores with mesopores on the walls, and the S/3DOHPPy demonstrates high specific capacity and stable cycling performance as a cathode for the Li/S batteries.392
