Abstract:
Zinc ferrite (ZnFe
2O
4) is used as a new anode material for the lithium ion batteries due to its excellent performance. However, ZnFe
2O
4 has the poor electrical conductivity and the serious volume effects during the charging and discharging, which results in the low cycle stability, fast capacity decay, and poor rate performance, limiting its application. Several methods for preparing the nano-ZnFe
2O
4 and ZnFe
2O
4 composites were introduced in this paper. The morphology and microstructure of the nano-scale ZnFe
2O
4 were studied by scanning electron microscope (SEM). The electrochemical performance of the products produced by the hydrothermal method, solvothermal method, electrospinning technology, co-precipitation method, and solid-phase reaction method were analyzed, and the real reasons that limited the ZnFe
2O
4 development were summarized.
