Porous membrane, method for producing the same, and lithium ion secondary battery using the same |
| abstract |
PROBLEM TO BE SOLVED: To provide an inexpensive separator having good shutdown characteristics and meltdown characteristics and excellent insulating properties. SOLUTION: A polyamideimide resin having a glass transition temperature of 70 ° C. or higher, a logarithmic viscosity of 0.5 dl / g or higher, and containing 20 mol% or more of the following structural formula (I) when all repeating structural units are 100 mol%. The present invention relates to a porous film having a total film thickness of 5 to 100 μm, including layers. 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. [Formula 4] [Selection figure] None |
