Abstract
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.
