中文摘要：

采用化学共沉淀法制备出层间分别含有SO42-和NO3-的铝取代氢氧化镍样品。利用X射线衍射（XRD）、傅里叶变换红外光谱（FT-IR）和扫描电子显微镜（SEM）对样品的微观结构和表面形貌进行了分析。采用循环伏安（CV）、交流阻抗（EIS）和充放电测试表征了样品的电化学性能。结果表明,层间含有NO3-的铝取代氢氧化镍比层间含有SO2-的铝取代氢氧化镍具有更好的电化学反应可逆性、更高的质子传递系数和放电比容量。

英文摘要：

Al substituted nickel hydroxide with interlayer SO2-4 or NO-3 were synthesized by chemical coprecipitation method and their microstructure and morphology were characterized by X-ray diffraction （XRD）,Fourier transform infrared （FT-IR）and scanning electron microscopy （SEM）.The electrochemical performance of these samples was measured by cyclic voltammetry （CV）,electrochemical impedence spectroscopy （EIS）and charge-discharge test.The results showed that better reaction reversibility,higher proton diffuse coefficient and discharge capacity were obtained for the nickel hydroxide with interlayer NO-3 than for that with interlayer SO2-4.
