POLYMER-ION-PERMEABLE MEMBRANE, COMPOSITE-ION-PERMEABLE MEMBRANE, BATTERY ELECTROLYTE MEMBRANE, AND ELECTRODE COMPOSITE BODY

摘要

The purpose of the present invention is to provide an ion-permeable membrane that is substantially free of holes and that has excellent ion permeability, heat resistance, strength, and flexibility, to provide a battery electrolyte membrane that uses the ion-permeable membrane, and to provide an electrode composite body. The present invention, which is for achieving said purpose, is a polymer-ion-permeable membrane that has an average radius of free volume of 0.32-0.50 nm.
