摘要：

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 center dot g(-1) after 100 cycles at the current density of 0.9 A center dot g(-1) with the 51% sulfur loading, which demonstrates that Mn2O3 hollow spheres could be a promising matrix for Li-S batteries.
