ABSTRACT
This work demonstrates a facile in situ synthesis of cobalt-manganese mixed sulfide (CoMn-S) nanocages on reduced graphene oxide (RGO) sheets by using a crystalline Co-Mn precursor as the sacrificial template. The CoMn-S/RGO hybrid was applied as the anode for Li-ion storage and exhibited superior specific capacity, excellent cycling performance, and great rate capability. In particular, lithium storage testing revealed that the hybrid delivered high discharge-charge capacities of 670 mA h g
