A　lithium-sulfur　battery,　a　potential　next-generation　secondary　battery,　is　affected　by　poor　conductivity　of　sulfur　and　the　dissolution　of　intermediate　polysulfides.　Here　we　report　a　lithium-sulfur　battery　with　ultrahigh　sulfur　loading　and　excellent　cycling　stability　using　porous　graphitic　carbon　(PGC)　as　a　high-conductivity　carrier　of　sulfur　and　carbon　fiber　with　crisscross　conductive　framework　as　an　electric　attachment　site　of　sulfur.　PGC　is　fabricated　through　a　simple　and　environmentally　friendly　synthesis　process　involving　high-temperature　graphitization　in　a　N-2　atmosphere　followed　by　an　annealing　process　in　air.　Due　to　the　presence　of　porous　graphitic　structure,　with　C-O　termination　groups,　PGC　endows　the　lithium-sulfur　battery　system　with　excellent　cycling　performance.　The　lithium-sulfur　battery　cathode　constructed　by　PGC　with　a　sulfur　loading　of　2.5　mg　cm(-2)　still　retains　a　high　specific　capacity　of　734.4　mA　h　g(-1)　after　200　cycles.　Meanwhile,　an　ultrahigh　sulfur　loading　of　12.8　mg　cm(-2)　for　a　CR2025　coin　cell　is　achieved,　which　is　the　highest　sulfur　loading　reported　in　the　literature　for　the　coin　cell.　The　ultrahigh　sulfur　loading　cell　also　shows　good　electrochemical　properties,　profiting　from　the　mesopores　terminated　with　C-O　groups,　high　specific　surface　area　of　1129.9　m(2)　g(-1)　and　high-conductivity　graphitic　structure.
