Claims20
A microporous membrane comprising (a) a hot-melt adhesive, (b) an engineering plastics, (c) optionally a tackifier and (d) optionally a filler.
A method of making a microporous membrane comprising the steps of (a) dissolving hot-melt adhesive, engineering plastics, and optionally a tackifier in an organic solvent, and then adding a pore former and optionally a filler to form a homogeneous slurry, (b) casting the slurry as a film onto a support substrate, (c) evaporating the solvent from the membrane, and (d) washing the resulting microporous membrane with water to form a microporous membrane.
A battery comprising (1) at least one positive electrode, (2) at least one negative electrode, (3) an electrolyte, and (4) a microporous membrane comprising (a) a hot-melt adhesive, (b) an engineering plastics, (c) optionally a tackifier and (d) optionally a filler.
