ABSTRACTHydrous RuO2 is a mixed metallic-protonic conductor that is used as a charge storage material in electrochemical capacitors and as an electrocatalyst. Previous structural analysis by Dmowski, et. al. has shown that RuO2 is a composite of ordered RuO2 nanoparticles that are surrounded by hydrous grain boundaries. In this paper, magnetic susceptibility (MS) is used to show that the hydrous RuO2 has both localized and delocalized electrons. The localized electrons are attributed to Ru3+ defects that decrease in concentration with decreasing water content. The delocalized electrons are represented by a temperature independent paramagnetic (TIP) component of the MS. The magnetic data is consistent with a structure having metallic nanoparticles whose electrons become more itinerant with decreasing structural water. We conclude that hydrous RuO2 stores charge analogously to double-layer capacitors in which charge is stored at the interface of the hydrous grain boundaries and the metallic nanoparticles, and that there is effectively no difference in the charge storage mechanisms of hydrous RuO2 and carbon.

Stretchable conductors are essential components in next-generation deformable and wearable electronic devices. The ability of stretchable conductors to achieve sufficient electrical conductivity, however, remains limited under high strain, which is particularly detrimental for charge storage devices. In this study, we present stretchable conductors made from multiple layers of gradient assembled polyurethane (GAP) comprising gold nanoparticles capable of self-assembly under strain. Stratified layering affords control over the composite internal architecture at multiple scales, leading to metallic conductivity in both the lateral and transversal directions under strains of as high as 300%. The unique combination of the electrical and mechanical properties of GAP electrodes enables the development of a stretchable lithium-ion battery with a charge-discharge rate capability of 100 mAh g−1 at a current density of 0.5 A g−1 and remarkable cycle retention of 96% after 1000 cycles. The hierarchical GAP nanocomposites afford rapid fabrication of advanced charge storage devices.
