摘要： Problem: The invention provides a separator for a lithium-ion secondary battery exhibiting excellent strength, wettability with nonaqueous electrolyte solutions, voltage endurance and cycle characteristics in lithium-ion secondary batteries, and a method of increasing the puncture depth of the separator. Solution: A separator for a lithium-ion secondary battery is formed of a microporous film comprising a polyolefin resin (A) as a major component, and a resin (B), at least portions of the surfaces of the micropores in the microporous film being coated with resin (B).

摘要： In accordance with at least selected embodiments, a battery separator or separator membrane comprises one or more co-extruded multi-microlayer membranes optionally laminated or adhered to another polymer membrane. The separators described herein may provide improved strength, for example, improved puncture strength, particularly at a certain thickness, and may exhibit improved shutdown and/or a reduced propensity to split.

摘要： Described herein is a multilayer microporous film or membrane that may exhibit improved properties, including improved dielectric break down and strength, compared to prior monolayer or tri-layer microporous membranes of the same thickness. The preferred multilayer microporous membrane comprises microlayers and one or more lamination barriers. Also disclosed is a battery separator or battery comprising one or more of the multilayer microporous films or membranes. The inventive battery and battery separator is preferably safer and more robust than batteries and battery separators using prior monolayer and tri-layer microporous membranes. Also, described herein is a method for making the multilayer microporous separators, membranes or films described herein.
