Abstract以Ni(NO_3)_2·6H_2O和NaOH为原料采用化学沉淀法制备了Ni(OH)_2电极材料。采用X射线衍射(XRD)和场发射扫描电子显微镜(FESEM)表征了样品的微观结构,结果表明该样品是具有片状纳米次级结构的β-Ni(OH)_2。采用循环伏安(CV)和电化学充放电测试研究了该β-Ni(OH)_2样品的储锂性能,结果发现该样品作为锂离子电池负极材料具有非常高的储锂活性,在50 mA·g~(-1)电流密度下其第3次循环放电比容量高于1550 mA·h·g~(-1);样品电极中的碳含量对其循环性能和倍率性都有显著影响,通过交流阻抗(EIS)测试分析了样品电极中碳含量的作用机理。
