In this communication, flower-like tetragonal ZnMn2O4 superstructures are synthesized by a facile low temperature solvothermal process. Characterizations show that these ZnMn2O4 superstructures are well crystallized and of high purity. The product exhibits an initial electrochemical capacity of 763mAhg−1 and retains stable capacity of 626mAhg−1 after 50 cycles. Its stable capacity is significantly higher than that of nanocrystalline ZnMn2O4 synthesized by a polymer-pyrolysis method. It is found that the higher capacity retention can be attributed to three-dimensional superstructural nature of the as-prepared flower-like ZnMn2O4 material. This study suggests that the solvothermally synthesized flower-like ZnMn2O4 is a promising anode material for lithium-ion batteries.
