Separator for Non-aqueous Secondary Battery |
| abstract |
An object of the present invention is to provide a separator for a non-aqueous secondary battery having excellent heat resistance and ion permeability, in addition to shutdown characteristics. 1st this invention is a separator for non-aqueous secondary batteries which consists of a porous composite membrane in which the heat resistant porous layer containing a heat resistant resin was formed in at least one surface of the base material which consists of a polyolefin microporous membrane, The film resistance (A) of a base material The Gurley value (B) of the base material, the film resistance (C) of the porous composite membrane, and the Gurley value (D) of the porous composite membrane satisfy the specific relationship. Moreover, 2nd this invention is characterized by the average pore diameter of the heat resistant porous layer calculated | required by the mercury porosimetry to be 0.1-0.2 micrometer. In a third aspect of the present invention, the average fibril diameter of the heat resistant resin fibrils is 10 to 80 nm, and the average pore diameter of the pores in the heat resistant porous layer is 50 to 250 nm. |
