摘要： 以SnCl4·5H2O,ZnCl2和N2H4·H2O为原料,用水热法制备Zn2SnO4纳米粉体.利用XRD,TEM和循环伏安等测试手段研究Zn2SnO4材料的结构、形貌及电化学性能.结果表明,当原料配比n(Zn)∶n(Sn)∶n(N2H4.H2O)=2∶1∶8时,180℃下水热合成24 h,得到晶型发育良好的纯相Zn2SnO4纳米材料.其首次放电和充电容量分别为1 634和709.7 mA.h/g,循环30次之后放电容量为483.7 mA.h/g,表现出较好的电化学性能.

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.
