Electroplated Thick Manganese Oxide Films with Ultrahigh Capacitance

Electroplated Thick Manganese Oxide Films with Ultrahigh Capacitance 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advanced Energy Materials Wiley

Abstract

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.
