An ion-permeable membrane is substantially free of holes and has excellent ion permeability, heat resistance, strength, and flexibility, and can form a battery electrolyte membrane that uses the ion-permeable membrane, and an electrode composite. The polymer-ion-permeable membrane has a per-unit-thickness puncture strength of 0.3-3.0 N/&#x3bc;m and a membrane resistance of 3.0-100.0 &#x3a9;&#xb7;cmat 25&#xb0; C.

Polymer-ion-permeable membrane, composite-ion-permeable membrane, battery electrolyte membrane, and electrode composite

An ion-permeable membrane is substantially free of holes and has excellent ion permeability, heat resistance, strength, and flexibility. A battery electrolyte membrane uses the ion-permeable membrane, and can form an electrode composite body. The polymer-ion-permeable membrane has an average radius of free volume of 0.32-0.50 nm.
