摘要：

The precursor of Zn-Mn oxides were synthesized by a facile hydrothermal method and subsequently calcined at different temperature of 400℃, 500℃, 600℃ and 700℃ in air in order to synthesis the hierarchical porous ZnMn2O4 microspheres assembled by a lot of nanosheets. The ZnMn2O4 microspheres synthesized by calcining precursor in air at 500℃ (ZMO-500) display rich hierarchical porous structures, and when used as the anode material of lithium ion batteries, ZMO-500 microsphere anode material exhibits a high discharge capacity of 1 132 mAh/g after 500 cycles at a current density of 500 mA/g. It is believed that the outstanding electrochemical performance of ZMO-500 microsphere anode material benefits from the hierarchical porous structure that can not only increase the contact area between the electrode and the electrolyte to facilitate the transfer of Li+, but also provide sufficient space for volume expansion of the electrode during the cyclic process. © 2020, Editorial Board of JBUAA.
