abstract = "A model of proton transfer and storage in amorphous RuO2.xH2O was proposed to explain the relationship between the specific capacitance and the structure and water content in RuO2.xH2O materials. The morphologies and crystalline structures of RuO2 xH2O annealed at different temperatures were investigated using electrochemical (EC) methods, transmission electron microscope (TEM) and selected area electron diffraction (SAED) techniques, respectively. From EC measurements, it was found that the specific capacitance increased with increasing annealing temperature, and reached the maximum value at a critical temperature, at which the crystalline RuO2.xH2O started to be formed. It was also found from EC measurement that proton conductivity is low for RuO2.xH2O at steady-state. From the SAED patterns, the structure disorder brought about by proton insertion was obtained from a sample annealed at the critical temperature. From 1H nuclear magnetic resonance (NMR) spectroscopy, it was demonstrated that the activation energy of proton in RuO2.xH2O samples is directly associated with the proton transport and storage ability of these materials. The proton intercalation mechanism was proposed.",
