In accordance with at least certain embodiments, a multilayer dry process polyethylene/polypropylene/polyethylene microporous separator which is manufactured using the inventive process which includes machine direction stretching followed by transverse direction stretching and a subsequent calendering step as a means to reduce the thickness of the multilayer microporous membrane, to reduce the percent porosity of the multilayer microporous membrane in a controlled manner and/or to improve transverse direction tensile strength. In a very particular embodiment, the inventive process produces a thin multilayer microporous membrane that is easily coated with polymeric-ceramic coatings, has excellent mechanical strength properties due to its polypropylene layer or layers and a thermal shutdown function due to its polyethylene layer or layers. The ratio of the thickness of the polypropylene and polyethylene layers in the inventive multilayer microporous membrane can be tailored to balance mechanical strength and thermal shutdown properties.

摘要： A new or improved microporous monolayer, bilayer, trilayer, or multilayer membrane, separator membrane, separator, or coated separator is disclosed. The membrane is preferably made up of at least one resin or polymer and at least one additive. The additive may comprise at least one material that improves adhesion of the microporous membrane to a coating, including a polyaramid-containing coating and a PCS coating, or to a different material such as a metallic surface, including an electrode surface. Improvements in adhesion are based on comparisons to similar microporous membranes without the at least one additive. In some preferred embodiments, the at least one additive may comprise, consist of, or consist essentially of a functionalized polymer or the combination of a functionalized polymer and an elastomer. In some embodiments, the functional group of the functionalized polymer may be maleic anhydride (MAH).
