Zinc hydroxystannate (ZnSn(OH)(6)) was prepared by a hydrothermal method and proposed as a novel anode active material for Zn/Ni secondary battery. The results of XRD and SEM revealed that the product is pure ZnSn(OH)(6) with cubic structure. As anode material for Zn/Ni secondary battery, ZnSn(OH)(6) exhibits excellent electrochemical properties: a high discharging platform of similar to 1.805 V and a good cycle ability with the retention ratio 98.5% after 800 cycles. These fascinating properties could be attributed to the Sn species can be reduced into Sn metal and it will form a highly conductive network, which is beneficial to improve the electrical contact between active material particles and diminish the polarization of the electrode. These results show that ZnSn(OH)(6) is capable of undergoing an inner redox reaction and can be used as a promising anode candidate for Zn/Ni secondary battery. (C) 2016 The Electrochemical Society.
