Abstract: In an embodiment of the disclosure, a separator utilized in a lithium battery is provided. The separator includes a non-woven polyester support, a porous layer of polyvinylidene fluoride (PVDF) or its derivatives formed on the non-woven polyester support, a layer of UV-curing or thermal-curing polymers formed on top of the porous layer of polyvinylidene fluoride (PVDF) or its derivatives.

Abstract: Provided is a low water-vapor permeable composite film, which includes a 3-layered co-extruded biaxial-oriented film formed of polyester films or polypropylene films including a first layer, a second layer and a third layer stacked in sequence. The first layer further includes an anti-block agent. An alternate structure including a plurality of organic protection layers and a plurality of inorganic layers are formed on the 3-layered co-extruded biaxial-oriented film. The plurality of organic protection layers and the plurality of inorganic layers are stacked alternately. The inorganic layers are formed by atom layer deposition.

Abstract: A multilayer battery separator is provided. The multilayer battery separator includes a porous polyethylene (PE) film, and a porous thermal resistant film selected from a group consisting of: a weight ratio of polyvinylidene fluoride (PVDF) and cellulose of 90/10-40/60; a weight ratio of polyvinylidene fluoride and polyethylene glycol (PEG) of 99/1-85/15; and polyimide (PI), and combinations thereof. A method for manufacturing the multilayer battery separator is also provided.

Abstract: The invention provides a oriented white polyester film, which includes at least one polyester film with a cavitation additive, wherein the cavitation additive includes poly(methyl methacrylate-co-methyl methacrylamide), a copolymer of sulfophthalate salt and nylon, polyarylate (PAR), ethylene methacrylate (EMA), ethylene methacrylate acrylic acid terpolymer (EMAAA), polyetherimide (PEI), metallocene catalyzed cyclic olefin copolymer (mCOC) or combinations thereof.
