摘要： A battery separator for a lithium battery is disclosed. The separator has a microporous membrane and a coating thereon. The coating is made from a mixture of a gel forming polymer, a first solvent, and a second solvent. The first solvent is more volatile than the second solvent. The second solvent acts as a pore former for the gel-forming polymer.

摘要： A separator for a high energy rechargeable lithium battery including a ceramic composite layer and a polymeric microporous layer. The ceramic layers includes a mixture of inorganic particles and a matrix material. The ceramic layer is adapted, at least, to block dendrite growth and to prevent electronic shorting. The polymeric layer is adapted, at least, to block ionic flow between the anode and the cathode in the event of thermal runaway.

摘要： A microporous battery separator is provided having a first co- extruded multilayered portion and a second co-extruded multilayered portion. The two portions are bonded together. In a preferred embodiment, the battery separator has two substantially identical multilayered portions bonded together face-to-face. Each of the two multilayered portions has at least one strength layer and at least one shutdown layer. Methods for making the battery separators are also provided. Preferably, a tubular multilayered film is extruded, and collapsed onto itself to form a multilayered battery separator precursor. The precursor is then bonded and annealed before it is stretched to form a microporous multilayer battery separator.

摘要： A split resistant microporous membrane is provided for use in preparing a battery separator. The microporous membrane has a TD tensile strength to MD tensile strength ratio of from about 0.12 to about 1.2, preferably from about 0.5 to about 1. The microporous membrane is made by a process which includes the steps of preparing a film precursor by blown film extrusion at a blow-up ratio of at least 1.5, annealing the film precursor, and stretching the resultant annealed film precursor to form the microporous membrane.

摘要： This invention provides a battery separator of improved resistance to splitting and puncture strength having five microporous membranes laminated together. The first, third, and fifth membranes are strength layers, and preferably are polypropylene. The second and fourth layers are shutdown layers, and preferably are polyethylene. The present invention is based on the discovery that a penta-layer separator having a construction of polypropylene-polyethylene-polypropylene-polyethylene-polypropylene has much greater resistance to splitting than a trilayer separator having a polypropylene-polyethylene-polypropylene construction with the same thickness.
