Lithium sulfur is considered as one of the most potential candidate cathode material using in high-energy lithium ion batteries. In this work, the N-doped porous carbon spheres with an appropriate N doping (4.33wt%) were synthesized by Pyrrole through the sulfuric acid triggered polymerization and carbonized directly. The diameter of obtained N-doped porous carbon spheres was in the range of 100-500nm, with the pore size of 2-20nm. Nitrogen-doped carbon/Sulfur cathode with 61.8wt% sulfur content exhibits excellent performance in high-energy lithium sulfur battery. The specific capacity reached 1660mAh g (-1) at 0.05 C and about 500mAh g(-1) at 2 C.
