Oxygen Reduction Activity of Carbon-Conductive Polymer-Silver Composite Electrodes

Abstract

Preparation, characterization, and electrochemical activity of a novel three-component composite electrode consisting of a carbon substrate with conductive polymer and silver coatings are described here. The composite electrode concept is described and the composite electrode is evaluated as a cathode for non-aqueous oxygen reduction. Improvement of cathode oxygen reduction activity will increase current capability and power output of metal air batteries, facilitating future development of small, lightweight, long-life power sources.
