摘要/Abstract

摘要： 应用无模板水热法成功制备了由超薄氧化镍纳米片组装而成的具有分级结构的多孔氧化镍，并研究了其电容性能。结果表明：扫速为20 mV?s-1时，质量比电容值435 F?g-1,循环1000周期之后，电容值基本没有衰减；电流密度为10 A?g-1时，质量比电容值为367 F?g-1。该材料是一种非常有前景的超级电容器材料。

Abstract: A facile and template-free hydrothermal method is proposed to successfully synthesize porous NiO hierarchical structure, which is found to be assembled from ultrathin NiO nanosheets. As for electrochemical pseudocapacitor application, the obtained material exhibits not only high specific capacitances of 435 F?g-1 at 20 mV?s-1 and 367 F?g-1 at 10 A?g-1, but also holds a good electrochemical stability over 1000 cycles at a current rate of 20 mV?s-1. These results suggest that the hierarchical structured porous NiO is a promising supercapacitor electrode material.
