Abstracts:

PROBLEM TO BE SOLVED: To provide a wound body of a separator having a thermoplastic polymer coated layer containing a thermoplastic polymer, which is capable of suppressing winding misalignment and wrinkling of a wound body without impairing adhesiveness between a separator and an electrode, (EN) A wound body of a separator for an electric storage device capable of reducing blocking. SOLUTION: The wound body of the electric storage device separator is characterized in that the separator comprises a polyolefin porous base material and a thermoplastic polymer coating layer containing a thermoplastic polymer on at least a part of at least one side of the base material , The winding body has a winding number of 1000 times or more and 10,000 times or less and a peeling strength between the separators in the innermost layer is 0.5 mN / mm or more and 10 mN / mm or less, in the separator for an electric storage device Wound body. 【Selection drawing】 None
