| Outline of Final Research Achievements |
In this study, stable gel membranes were prepared from aqueous and organic electrolytes by using silica nanofibers with surface silanol groups and a higher aspect ratio. The nanofiber composite gels prepared from various electrolyte solutions exhibit the maximum ionic conductivities of the order of 0.01 S/cm at room temperature and can be used as stable electrolyte membranes in various electrochemical devices such as electric double layer capacitors, fuel cells, metal anode secondary batteries, and sensitized thermal cells. Furthermore, the formation of interactions between the nanofiber surface and an electrolyte component can improve the device properties
