Abstract Sn doped ZnFe2O4 samples were prepared by co-precipitation method. It is found that with the increase of Sn content, the phase structure of the prepared samples transformed from single-phase spinel ZnFe2O4 to two-phase ZnFe2O4/SnO2 composite and the particle size of samples decreased; The Sn doped ZnFe2O4 (with Sn/Fe ratio of 0.05) exhibited the best lithium storage performance among the four samples. For example, after 300 cycles at 1000 mA g−1, the Sn doped ZnFe2O4 (with Sn/Fe ratio of 0.05) delivered a reversible capacity of 1163 mA h g−1, much higher than that (715 mA h g−1) of the undoped ZnFe2O4.

具有增强锂存储性能的掺锡 ZnFe2O4 负极材料

摘要 采用共沉淀法制备了Sn掺杂ZnFe2O4样品。发现随着Sn含量的增加，所制备样品的相结构由单相尖晶石ZnFe2O4转变为两相ZnFe2O4/SnO2复合物，样品粒径减小；Sn掺杂的ZnFe2O4（Sn/Fe比为0.05）在四种样品中表现出最好的储锂性能。例如，在 1000 mA g-1 下循环 300 次后，Sn 掺杂的 ZnFe2O4（Sn/Fe 比为 0.05）提供了 1163 mA hg-1 的可逆容量，远高于 (715 mA hg-1)未掺杂的 ZnFe2O4。
