WOUND ELECTRODE ASSEMBLY FOR NONAQUEOUS ELECTROLYTE RECHARGEABLE BATTERY, NONAQUEOUS ELECTROLYTE RECHARGEABLE BATTERY INCLUDING THE SAME, AND METHOD FOR MANUFACTURING THE SAME

摘要

A wound electrode assembly for a non-aqueous electrolyte rechargeable battery, the wound electrode assembly including a positive electrode, a negative electrode, and 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 the surface of the porous film. The adhesive layer includes a fluorine resin-containing particulate, a binder particle supporting the fluorine resin-containing particulate and having a smaller total volume than that of the fluorine resin-containing particulate, and a heat-resistant filler particle. 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 about 10 nm to about 100 nm.
