The search for new pseudocapacitor materials has led researchers into the field of metal oxides. Ruthenium oxide, in particular, exhibits high energy density while maintaining the high power density of traditional capacitors. Building this material into various nanostructures can maximize efficiency, but is difficult due to its brittle nature. Recent discoveries have shown that when combined with organic polymers such as PEDOT or polypyrrole, structural stability can be vastly improved without compromising the high energy or high power properties. Herein we report the synthesis, characterization and electrochemical properties of RuO2/PEDOT composite nanotubes and discuss their relevance to current energy storage technologies.
