利用脱合金纳米多孔金属的开孔性，在一种新型夹心电极中负载大量MnO 2，可以实现超高的比电容和优异的循环保持率。高导电纳米多孔金属作为活性材料的载体和超级电容器的集流体，显著提高了三相界面的电子/离子导电性和电荷转移。
Ultrahigh specific capacitance and excellent cyclic retention of MnO2 can be achieved in a novel sandwich electrode loaded with a large amount of MnO2 by utilizing the open porosity of dealloyed nanoporous metals. The highly conductive nanoporous metals, as both support of active materials and current collector of supercapactior, dramatically enhance the electronic/ionic conductivity and charge transfer at three phase interfaces.
