Notes:
When fine-sized 45ZnO·55P2O5 or 50ZnO·50P2O5 glass powders were mixed withdistilled water, hydration immediately occurred, resulting in the formation of viscous hydrogels. 31PMAS-NMR spectra showed that the hydrogels contain orthophosphates and long-chain phosphates;no significant differences in their structures between the hydrogels were shown. The 45ZP gel and50ZP gel showed high conductivities (e.g., 9.9 and 2.8 mS/cm, respectively, at 30°C). Theconductivities were related to the proton amount in the hydrogel; the amount in the 45ZP gel waslarger than that in the 50ZP gel. Electric double-layer capacitors (EDCs) were prepared usingelectrolytes consisting of the hydrogels. The specific capacities of the EDC cell for the 45ZP gel and50ZP gel were 2.40 and 2.06 F/g, respectively. The possibility as an EDC electrolyte may be related toproton conductivities of the hydrogels
