With　the　aim　to　obtain　high　performance　cathode　materials　for　lithium-sulfur　batteries,　composite　of　mesoporous　carbon　(MC)　loaded　with　ZnS　(ZnS/MC)　was　prepared　through　ultrasonic　dispersion　and　heat　treatment.　The　as-prepared　composite　was　blended　with　elemental　sulfur　by　heating,　then　cathode　materials　(ZnS/MC/S)　was　obtained.　The　ZnS/MC　composite　was　characterized　by　XRD,　SEM,　EDS　and　N2　adsorption-desorption　isotherms.　The　results　showed　that　ZnS　particle　was　uniformly　loaded　to　the　surface　of　MC　through　ultrasonic　dispersion　when　content　of　ZnS　was　less　than　17wt%.　ZnS　nanoparticles　aggregated　to　form　sphalerite　ZnS　by　heat　treatment　or　increasing　content　of　ZnS.　Cyclic　voltammetry　test　showed　that　ZnS　accelerated　the　oxidation　process　of　polysulfides.　Charge/discharge　tests　indicated　that　the　initial　discharge　specific　capacity　was　1354.6　mAh/g,　while　the　coulombic　efficiency　of　the　first　charge　and　discharge　was　98.7%.　The　capacity　still　remained　650　mAh/g　after　50　cycles.
