Abstract
The flower-like ZnMn2O4 hollow microtubules were synthesized by a hydrothermal method and calcination method. The composition and morphology were characterized. The results showed that flower-like hollow microtubules were obtained through calcination treatment. The as-prepared ZnMn2O4 electrochemical properties of flower-like hollow microtubules anode material for lithium-ion batteries were investigated. The first charge and discharge capacity was measured at 2152/1263 mA h g−1 when the current density at 400 mA g−1. After 300 cycles, the capacity kept 515 mA h g−1 corresponding to the coulombic efficiency of 99%, which exhibited preferable cycling performance. The stability of the structure has been shown by rate performance, which had been tested under different current density. The results suggest a promising application of the ZnMn2O4 as anode material for lithium-ion batteries.
