The Inside Cover picture shows a gold nanowire electrode (top), and a coaxial nanowire electrode with nanowires that have a gold core and a polypyrrole shell (bottom). The coaxial nanowire electrode has the ability to store a large amount of energy through the pseudocapacitance of the outer polypyrrole layer, and charge can be transferred to the inner gold core at fast rates, making it ideal for use in pseudocapacitors. This coaxial structure is effective at reducing the internal resistance of the electrode and the energy density is increased without a noticeable deterioration of power density.
