POROUS FILM, METHOD FOR MANUFACTURING THE SAME, AND CELLU THE LITHIUM-ION SECONDARY MANUFACTURED WITH SAID FILM |
| abstract |
[PROBLEMS] To provide an inexpensive separator satisfactory in shutdown properties and meltdown properties and having excellent insulating properties. [MEANS FOR SOLVING PROBLEMS] A porous film having a thickness of 5 to 100 µm, characterized by comprising a porous layer of a polyamide-imide resin which has a glass transition temperature of 70°C or higher and an inherent viscosity of 0.5 dl/g or higher and comprises units represented by the following structural formula (I), the amount of the units being 20 mol% or more based on all repeating structural units. Also provided is the porous film which is characterized in that the porous polyamide-imide resin layer has an amide bond/imide bond ratio of from 10/90 to 45/55. Furthermore provided is a lithium-ion secondary cell which comprises a positive electrode and a negative electrode which are capable of occluding/releasing lithium ions and either of the porous films disposed as a separator between the electrodes. |
