摘　　要：超级电容器是一类电化学能量储存装置,被广泛应用于混合动力汽车、新能源收集转换、大功率工程机械和移动电子设备等领域。超级电容器的电极材料要求具备有效可控的多孔结构和比表面积,合理的孔径分布以及良好的导电性和易成型。纳米多孔铜是一类具有高导电性、高比表面积、孔径可控以及良好电容特性的多孔材料,可作为超级电容器的集流体负载更多的活性物质,进而大大提高超级电容器的能量密度。此外,改性纳米多孔铜可增强多孔铜基底的物化稳定性并且保留了更多活性位点,为超级电容器的电极可控设计提供了一定的思路。Supercapacitors are widely used as an energy storing device in a wide range of communication, transportation and daily life,including hybrid electric vehicles, new energy collection and conversion, high-power construction machinery, mobile electronic equipment,and so forth. The electrode materials of supercapacitor require effective, controllable porous structure, specific surface area, a reasonable pore size distribution, good electrical conductivity and easy molding. Nanoporous copper is a kind of porous material with high conductivity, high specific surface area, controllable aperture and good capacitance. It can be used as a current collector loading more active materials for supercapacitor, thus greatly improving the energy density of supercapacitor. In addition, the modified nanoporous copper can enhance the physical and chemical stabilities of porous copper substrate and retain more active sites. It offers a kind of idea for controllable electrode design of supercapacitors.
