High-powered Electrochemical Energy Storage Devices and Methods for their Fabrication
The present invention relates to electrochemical storage devices, such as supercapacitors, batteries, etc., and more particularly to such devices that comprise an electrochemically active coaxial nanowire. The invention particularly concerns such devices in which the coaxial nanowire comprises an inner core of a transition metal oxide and an axially surrounding outer shell composed of an electroconductive organic polymer, such as poly(3,4- ethylenedioxythiophene) (PEDOT). The invention particularly relates to a facile method for achieving the self-assembly of such coaxial nanowires.
