    摘要: An improved multilayer laminated microporous battery separator for a lithium ion secondary battery, and/or a method of making or using this separator is provided. The preferred inventive dry process separator is a tri-layer laminated Polypropylene/Polyethylene/Polypropylene microporous membrane with a thickness range of 12 μm to 30 μm having improved puncture strength and low electrical resistance for improved cycling and charge performance in a lithium ion battery. In addition, the preferred inventive separator's or membrane's low Electrical Resistance and high porosity provides superior charge rate performance in a lithium battery for high power applications.
