| 摘 要： | 在水热条件下，以碳球为模板合成了Mn2O3空心球，并用作锂硫电池的载硫基底材料。测试结果表明载硫量为51%的Mn2O3-S复合材料显示了较高的比容量，良好的循环稳定性和倍率性能。循环100圈后，最终可逆容量仍保持657 mA·g-1，证明该Mn2O3空心球是一种有潜力的载硫基底材料。

| Abstract: | Uniform Mn2O3 hollow spheres were synthesized by using carbon spheres as the hard template and were used as holder for Li-S batteries. The Mn2O3-S composites showed a high specific capacity, good cycling stability and rate performance. The final reversible capacity can remain at 657 mA·g-1 after 100 cycles at the current density of 0.9 A·g-1 with the 51% sulfur loading, which demonstrates that Mn2O3 hollow spheres could be a promising matrix for Li-S batteries. |
