Synthesis and electrochemical properties of cubic-like ZnMoO4 anode materials

Abstract

We prepared cubic-like ZnMoO4 anode material via precipitation-freeze drying method and calcining directly in the air using zinc acetate and ammonium molybdate tetrahydrate as raw materials. Through various characterization methods, the structure, morphology and electrochemical properties of cubic-like ZnMoO4 were studied. By comparing the structure and morphology of cubic-like ZnMoO4 and ordinary ZnMoO4, cubic-like ZnMoO4 had a smaller particle size and good dispersibility. In addition, compared with ordinary ZnMoO4, the electrochemical performance of cubic-like ZnMoO4 was improved. When accepted as an anode material for lithium-ion secondary batteries, the cubic-like ZnMoO4 provided a discharge capacity of 457.7 mAh g−1 at a current density of 0.1 A g−1 after 100 cycles. Moreover, it exhibited excellent electrochemical properties even at high current densities. The electrochemical results indicated that the cubic-like ZnMoO4 has high capacity, good rate ability, and outstanding cycle stability.
