Zn 3 Mo 2 O 9 with various morphologies were constructed using hydrothermal, solvothermal, and high-temperature solid-phase strategies and used as negative electrodes of lithium-ion batteries firstly. The Zn 3 Mo 2 O 9 obtained by high-temperature solid-state method (ZMO-t) is constructed by lots of small nanosheets, which has relatively uniform size and small particles among three samples. The unique morphology is beneficial for electrolyte permeation and further promotes the migration rate of lithium ions. At various current densities, test results can illustrate that the ZMO-t exhibited the best electrochemical performance than those of Zn 3 Mo 2 O 9 obtained by solvothermal method (ZMO-s) and hydrothermal way (ZMO-h) materials at the same rates. Based on these results, the Zn 3 Mo 2 O 9 synthesized via high-temperature solid-state strategy has the potential to become a novel negative electrode for Li-ion batteries going forward.
