Layered porous film, and non-aqueous electrolyte secondary battery
Abstract:
A laminated porous film includes a porous base material layer containing polyolefin as a main component; a filler layer containing inorganic particles as a main component; and a resin layer containing resin particles as a main component, the resin particles showing an endothermic curve satisfying conditions (1) and (2) below, the endothermic curve being obtained by differential scanning calorimetry. Condition (1): a temperature at which DDSC is not less than 0.10 mW/min/mg is not less than 70° C. Condition (2): endothermic amount calculated from an area of the endothermic curve in a range of not less than 50° C. and not more than 70° C. is not less than −20.0 J/g.
