| 摘 要： | 为了考察阴离子种类对掺杂Co2+纳米Ni(OH)2性能的影响,采用不同镍盐制备出掺杂Co2+纳米Ni(OH)2,并采用X射线衍射(XRD)、透射电子显微镜(TEM)、循环伏安技术(CV)和恒流充放电方法对材料物化性能和电化学性能进行了研究.研究结果表明,掺杂Co2+的纳米Ni(OH)2为β-Ni(OH)2,衍射峰发生明显宽化.样品颗粒的尺寸为60~100 nm,阴离子的变化对制得的Ni(OH)2的表观形貌有影响.恒流充放电实验表明,阴离子为NO3-时,样品的质量比容量较高,0.2 C放电达到了234.6 mAh.g-1.循环伏安测试表明,阴离子为SO42-时,样品有较好的可逆性,阴离子为NO3-或SO42-时有较高的质子扩散系数.

| Abstract: | Co2+-doped nano-Ni(OH)2was prepared with different nickel salts in order to investigate the effects of anions on the performance of nano-scale Ni(OH)2,and XRD,TEM,cyclic voltammetry and charge-discharge technique were applied to study the physicochemical and electrochemical properties of the nano-Ni(OH)2.Results show that the samples prepared are beta-phase Ni(OH)2,and diffraction peaks are broadened.The particle size ranges from 60 nm to 100 nm,and the surface morphology of samples varies with the used nic... |
