| 摘 要： | 采用水热法制备锌铝铈水滑石（Zn-Al-Ce-LDHs），并且将其作为锌镍二次电池的新型负极材料。利用红外光谱（FTIR）、X射线衍射仪（XRD）和扫描电镜（SEM）对制备的Zn-Al-Ce-LDHs进行了形貌和微观结构的分析。通过循环伏安曲线（CV）、Tafel极化曲线和恒电流充电放电测试研究了Zn-Al-Ce-LDHs作为锌镍电池负极材料的电化学性能。XRD和SEM分析发现，制备的Zn-Al-Ce-LDHs结晶度完好、分散均匀并且呈现出了规则六边形片状结构。电化学性能研究结果表明，Zn-Al-Ce-LDHs应用到Zn-Ni二次电池中表现出了很好的循环可逆性能和抗腐蚀性能；恒电流充电放电测试结果分析可知，Zn-Al-Ce-LDHs电极表现出了较为优异的循环稳定性以及充放电特性，经过80次循环后，循环保持率可以达到95.1%。 |

| Abstract: | Zn-Al-Ce-LDHs was prepared by hydrothermal method and then used as a new negative material for Zn-Ni secondary battery. The morphology and microstructure of Zn-Al-Ce-LDHs were analyzed by FTIR, XRD and SEM. The electrochemical properties of Zn-Al-Ce-LDHs as the negative electrode materials for Zn-Ni secondary battery were studied by cyclic voltammetry (CV), Tafel polarization curve and constant current charge discharge test. XRD and SEM analysis showed the prepared Zn-Al-Ce-LDHs had nice crystallinity, uniform dispersion and a regular hexagonal sheet structure. The electrochemical tests showed that the Zn-Al-Ce-LDHs had good cycle reversibility and corrosion resistance when it was applied in Zn-Ni secondary battery. The galvanostatic charge and discharge tests also indicated that Zn-Al-Ce-LDHs electrode had excellent cycle stability and charge-discharge characteristics. After 80cycles, the cycle retention rate was 95.1%. |
