| Nanostructured mesoporous architectures created by sol-gel chemistry consist of bicontinuous networks of solid and pores and combine high surface area with molecular accessibility. These three-dimensional architectures exhibit enhanced electrochemical properties for charge-storage devices such as batteries and ultracapacitors. We synthesize nanoarchitectures based on hydrous manganese dioxide and vanadium pentoxide as candidates to explore how control of the pore-solid architecture and controlled preparation of vacancies can improve the electrochemical performance of energy-storage materials that avoid the use of nickel- and cadmium-based chemistries. We also create new inorganic/organic hybrid nanoarchitectures with improved properties by the electrodeposition of ultrathin conformal polymer coatings directly on the oxide surface. |
