采用柠檬酸盐溶胶-凝胶法制备了组成为Li1+2xZn1-xPO4 (x=0,0.1, 0.14,0.2,0.3,0.4,0.5)的固体粉末和烧结体。对其结构的研究结果表明，在这样的组成范围内，采用溶胶-凝胶法得到了一系列 α-LiZnPO4（x=0）、Li9Zn6(PO4)7(x=0.14)、α-Li4Zn(PO4)2(x=0.5)单相以及由 α-LiZnPO4+Li9Zn6(PO4)7、α-Li4Zn(PO4)2+ Li9Zn6(PO4)7 两相构成的混合相，用这种合成方法得到的样品的生成温度较传统的固相合成样品降低了约 400 ℃。用交流阻抗技术测定了样品的导电性，其中 α-LiZnPO4、Li9Zn6(PO4)7 在室温下不显示导电性，而 α-Li4Zn(PO4)2 具有较高的导电性，t=25℃时，σ=1.66×10-6 S*cm-1。
The samples of Li1+2xZn1-xPO4(x=0,0.1,0.14,0.2,0.3,0.4,0.5) were prepared by citrate sol-gel method. The results on structure research show that the system contains several new phases:α-LiZnPO4(x=0),Li9Zn6(PO4)7 (x=0.14) and α-Li4Zn(PO4)2(x=0.5). Formation temperature of the samples prepared by this way was much lower than those prepared by solid state reaction. Ion conductivity of the sample was measured by ac-impedance spectrum, α-LiZnPO4,Li9Zn6(PO4)7 do not appear the property of ion conductivity at room temperature, however, the sample of α-Li4Zn(PO4)2 had a high Li cationic conductivity of 1.66×10-6 s*cm-1 at 25℃.
