Owing to the synergistic effect between two metals and a high oxidation state, β-ZnMoO4 shows a high theoretical specific capacity and acts as one active material for the design and construction of lithium-ion batteries. In this paper, β-ZnMoO4 structures were formed by one hydrothermal process and characterized with XRD, SEM, Raman and XPS. The electrochemical performance tests demonstrate their excellent lithium storage capacity and cycling stability. At a current density of 2.0 A g−1, the reversible capacities of two formed β-ZnMoO4 microstructures were maintained at 665.5 and 704.6 mA h g−1 after 500 cycles. These characteristics prove that β-ZnMoO4 structures show interesting application prospects in portable energy storage devices.
