Wound electrode assembly for nonaqueous electrolyte rechargeable battery, nonaqueous electrolyte rechargeable battery including the same, and method for manufacturing the same

A wound electrode assembly for a non-aqueous electrolyte rechargeable battery, the wound electrode assembly comprising:

• a positive electrode,
• a negative electrode,
• a porous film between the positive electrode and negative electrode, the positive electrode, the negative electrode, and the porous film each being belt-shaped, and
• an adhesive layer on a surface of the porous film, wherein:
• the adhesive layer includes a fluorine resin-containing particulate, a binder particle supporting the fluorine resin-containing particulate, and a heat resistant filler particle,
• a total volume of the binder particle in the adhesive layer is smaller than a total volume of the fluorine resin-containing particulate in the adhesive layer,
• an average particle diameter of the binder particle is about 100 nm to about 500 nm,
• an average particle diameter of the heat-resistant filler particle is 10 nm to 95 nm,
• the fluorine resin-containing particulate includes polyvinylidene fluoride,
• the heat resistant filler particle includes a metal oxide particle, and
• the average particle diameter of the binder particle and the average particle diameter of the heat-resistant filler particle satisfy at least one of Equations 1 and 2, in which y is the average particle diameter of the binder particle and x is the average particle diameter of the heat-resistant filler particle,
• y<(50/17)*(x+70) (1)
• y>(10/7)*(120−x) (2).
