▎ 摘　　要

Thermally reduced graphene oxide (rGO)-wrapped ZnMn2O4 nanorods have been successfully fabricated via a facile bottom-up approach. Characterization results show that porous ZnMn2O4 nanorods are uniformly wrapped by ultrathin rGO sheets. The unique structure of this rGO-ZnMn2O4 composite could facilitate both ion and electron diffusion, thus providing suitable characteristics of an anode material for high performance lithium-ion batteries. Specifically, the conductive rGO sheets could act as an efficient buffer to relax the volume changes from Li+ insertion/extraction, and enable the structural and interfacial stabilization of ZnMn2O4 crystals. As a consequence, a high and stable reversible capacity (707 mA h g(-1) at 100 mA g(-1) over 50 cycles) and an excellent rate capability (440 mA h g(-1) at 2000 mA g(-1)) are achieved with this composite material.
