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.

摘要： [Problem] To provide a separator for electric storage devices that suppresses dendrite short circuits and has excellent thermal stability.
[Solution] Provided is a separator for electric storage devices including: (A) a microporous layer mainly composed of (X) isotactic polypropylene; and (B) a microporous layer containing (Y) isotactic polypropylene identical or different from the isotactic polypropylene (X), and (Z) thermoplastic resin different from the isotactic polypropylene (Y). The microporous layer (B) has a lower isotactic polypropylene content than the microporous layer (A), and the thermoplastic resin (Z) has a tensile modulus of from 3 MPa to 500 MPa.
