摘要： Novel or improved microporous single or multilayer battery separator membranes, separators, batteries including such membranes or separators, methods of making such membranes, separators, and/or batteries, and/or methods of using such membranes, separators and/or batteries are provided. 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： Disclosed herein is an asymmetric porous membrane having two outer layers and at least one inner layers. The outer layers may be asymmetric in thickness, pore size, porosity, tortuosity, or combinations thereof. In some embodiments, the asymmetric porous membrane has two outer layers and no inner layers. The thickness of one of the outer layers to the other of the outer layers is from 1.1 to 25:1, preferably from 1.1:1 to 10:1, 1.1:1 to 5:1 or 4:1 to 10:1. In some embodiments, both outer layers are PP-containing layers and in some embodiments, one outermost layer may be a PE-containing layer and the other may be a PP-containing layer. The asymmetric porous membrane may be used as or to make a battery separator. In some embodiments, the battery separator may include an asymmetric porous membrane having the thinner of the two outer layers or the layer facing the anode coated with a coating such as a ceramic coating. The battery separator may be used in a liquid electrolyte secondary battery. In the battery, the thicker of the outer layers and/or the PP-containing layer faces or is closest to the cathode and the thinner of the two outer layers and/or the PE-containing layer faces or is closest to the anode. The outer layer facing the anode may be coated with a coating such as a ceramic coating. The battery separators described herein may have electrochemical stability voltage equal to or above 4.2 v.s. Li/Li+.
