Abstract: An electrical storage system includes a first electrode, a second electrode, an insulated separator, and an electrolyte. The second electrode is spaced from the first electrode. The insulated separator is disposed between the first electrode and the second electrode. The separator further includes an agar and a fiber material. The electrolyte surrounds the first electrode and the second electrode.

Abstract: A membrane includes a fiber material (e.g., in fabric form) and an agar material distributed so as to surround the fiber material. Another membrane includes an agar material and a fiber material (e.g., non-woven fibers) dispersed in the agar. Moreover, a method for making the membrane includes the steps of: (a) mixing the agar material with water to form a slurry of agar; (b) immerging a fiber material into the slurry of agar to form a pre-composite; (c) molding the pre-composite to form a composite and solidifying the composite to obtain the membrane.
