Ternary metal oxides are considered as promising anode materials for lithium-ion batteries (LIBs), because they can circumvent the shortcomings of single-component oxides. Herein, a facile hydrothermal route combined with calcination is used to fabricate manganese cobalt oxide (MnCo2O4) hollow spheres comprised of many mesoporous nanosheets. When used as anode material, the MnCo2O4 hollow spheres display excellent electrochemical properties. A specific capacity of 1023mAhg(-1) can be achieved after 200cycles at a current density of 200mAg(-1). Even at a high current density of 5000mAg(-1), a reversible discharge capacity as high as 755mAhg(-1) can be achieved.
