摘要：
A novel structure of core-shell MnO2/S composite was designed as cathode materials for Li-S batteries. This structure could efficiently inhibit the polysulfide dissolution and improve the conductivity at the same time. As a result, the cycle performance of Li-S battery was greatly improved due to the presence of core-shell MnO2/S composite. The results show that the specific capacity of core-shell MnO2/S composite is 1200 mAh g(-1) at 0.1 C. After 100 cycles, the specific capacity remains 715 mAh g(-1) at 0.5 C, showing perfect cycle performance.
