Abstract

The precursors of ZnMn₂O₄ were synthesized by different methods (the rheological phase reaction method or the mixed solvothermal method). The precursors were heat-treated at a suitable temperature to obtain the expected product (ZnMn₂O₄). The synthesized samples were characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The electrochemical properties of the samples were also investigated. The results show that ZnMn₂O₄ was synthesized successfully. The particles of ZnMn₂O₄ were irregular quasi-spheres with sizes of about 50 nm. The ZnMn₂O₄ nanoparticles synthesized through the mixed solvothermal method were clustered together to form microspheres about 1 μm in diameter. The electrochemical testing results showed that the ZnMn₂O₄ synthesized through the mixed solvothermal method featured higher reversible capacity and better cycling performance than the sample synthesized by the rheological phase reaction method. The ZnMn₂O₄ synthesized through the mixed solvothermal method could be a promising anode material for lithium ion battery application.
