A method includes applying to a substrate a solution including a polymeric compound to form a release layer on the substrate; applying ion-conducting elements on the release layer; applying a matrix polymer on the release layer, wherein the matrix polymer surrounds at least some of the ion-conducting elements; and removing the release layer to separate the matrix polymer from the substrate such that the ion-conducting elements remain embedded in a carrier layer of the matrix polymer and form an ion-conducting membrane.

An energy storage device includes an anode; a cathode; an electrolyte in contact with both the anode and the cathode; and an electrically non-conductive separator between the anode and the cathode. The separator includes a membrane having a plurality of voids, wherein at least some of the voids are partially filled with inorganic particles, and wherein the inorganic particles exhibit a shear modulus greater than the shear modulus of the membrane.
