Abstract: The powdered Zn2SnO4 with nanoparticles were hydrothermally synthesized with SnCl4 · 5H2O, ZnCl2 and N2H4 · H2O as starting materials. The crystal structure, morphology and electrochemical properties of the powdered Zn2SnO4 were investigated by XRD, TEM and galvanostatic charge-discharge test. The results showed that when the molar ratio ZnCl2:SnCl4:N2H4 · H2O=2:1:8 and hydrothermal synthesis was done at 180°C for 24 h, the pure powdered Zn2SnO4 present the well-growing crystal form and good electrochemical properties. The initial discharging and charging capacity of powdered Zn2SnO4 are 1634 mA·h/g and 709.7 mA·h/g, respectively, and its discharging capacity after 30 cycles is 483.7 mA·h/g.
