Abstract: A method of making a polyelectrolyte complex membrane separator for a Lithium-Sulfur battery to support lean electrolyte operation, comprising the steps of: forming polyelectrolyte complex nanoparticles by the addition of polyethylenimine (PEI) to tannic acid (TA); adding bovine serum albumin (BSA); purifying the nanoparticles; re-dispersing the nanoparticles in water to form a nanoparticle suspension; and dipcoating a polyolefin membrane in the nanoparticle suspension.
