1. a preparation method for high cycle performance lithium-sulfur cell S-C anode composite material, its concrete steps are as follows:

  • (1) sublimed sulfur and material with carbon element being put into ball mill for dry grinding mixes;

    (2) the good S-C composite powder of ball milling is put on microwave oven specimen rotating holder, after microwave oven body is vacuumized, passed into protection gas, be heated to the melt temperature of sulphur, insulation, makes S-C microwave composite material;

    (3) by the S-C microwave composite material making and conductive agent ground and mixed evenly after, then be dispersed in solvent with binding agent, stir, make slurry;

    (4) slurry modulating is evenly coated on collector thin slice, after vacuumize, makes S-C anode composite material.
