Study on the design and construction of β-ZnMoO4 microstructures and their enhanced electrochemical performance as anodes for lithium-ion batteries

Abstract

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.
