Porous membrane, method for producing the same, and lithium ion secondary battery using the same |
abstract |
PROBLEM TO BE SOLVED: To provide a separator for a lithium ion secondary battery excellent in a balance between shutdown characteristics and meltdown characteristics. A porous film having a glass transition temperature of 70 ° C. or higher, a logarithmic viscosity of 0.5 dl / g or higher, and a polyamideimide resin layer containing an isophorone structure as an amine component and having a total film thickness of 5 to 100 μm. About. The present invention also relates to a lithium ion secondary battery in which the porous membrane is interposed as a separator between a positive electrode and a negative electrode capable of inserting and extracting lithium ions.
