【摘要】 采用化学沉积法制备了表面包覆氧化铟的氧化锌复合材料。利用X射线衍射(XRD)、透射电子显微镜(TEM)、Tafel曲线以及充放电循环(用做锌镍电池的负极材料)等方法,对包覆前后的氧化锌样品进行了表征。结果表明,包覆物的化学成分为氧化铟,该包覆物在氧化锌表面为部分包覆;包覆后的氧化锌材料具有更好的耐腐蚀性能,且电化学循环性能良好,经过179次循环后,放电容量仍保持设计容量的81.17%。更多还原

【Abstract】 Indium compound was coated on the surface of the zinc oxide by chemical deposition.The properties of the samples were characterized by X-ray diffraction(XRD),transmission electron microscope(TEM),Tafel plot and charge-discharge test as the negative electrode materials of Ni/Zn battery.The results show that the chemical composition of coating material,indium oxide.Indium oxide can be partly coated on the surface of zinc oxide.The as-prepared zinc oxide has a better alkali-tolerant performance than pure zinc oxide.Furthermore, this sample shows much better capacity retention,and it can be retained about 81.17%after 179 charge-discharge cycles.更多还原
