Porous film, rechargeable battery separator and rechargeable battery |
| abstract |
An object of the present invention is to provide a porous film having high adhesiveness to an electrode and having excellent thermal dimensional stability and battery characteristics. A porous film formed by laminating a porous layer composed of inorganic particles and organic resin particles on at least one surface of a porous base material, and the mass content α of the inorganic particles contained in the porous layer is 50 mass. % Or more and 95% by mass or less, and when the maximum value when the surface elastic modulus of the porous layer is measured 50 times is γ, the ratio of the number of times the surface elastic modulus is measured within the range of γ / 2 or less. Is a porous film having a value of 30% or more and less than 100%. |
