(57) Abstract: A porous membrane capable of easily obtaining a separator for an electrochemical element comprising a porous membrane in which voids are filled with a solid electrolyte with high productivity, and an electricity comprising such a separator. It is to provide a chemical element, in particular a battery, a capacitor or a separator for a capacitor. According to the present invention, a reversible gelling agent capable of forming a reversible sol-gel electrolyte composition is supported together with an electrolyte salt and a solvent for the electrolyte salt. A porous membrane for a separator for an electrochemical device is provided. Further, according to the present invention, there is provided a separator for an electrochemical device obtained from such a porous membrane and an electrochemical device including such a separator, particularly such an electrochemical device for a battery, a capacitor or a capacitor. Is done. |
