For example, these ion-conductive liquids are used for electrolytes such as nickel-cadmium batteries and lithium-ion batteries. However, there is a possibility that the liquid may leak out from the device using the ion conductive liquid in a long term, and there is a problem in reliability. In order to overcome this drawback, in recent years, research and development of solid ion conductive materials have been carried out.

However, it has not yet spread as a solid ion conductive composition. In addition, plasticization with a highly polar solvent is considered to be effective in improving ionic conductivity, but on the other hand, there is a high possibility that mechanical strength is reduced, which causes inconvenience when manufacturing and using devices using this. This is not always a good method, as it may occur.
