Abstract:
An electrode wound element for a non-aqueous electrolyte rechargeable battery includes a belt-shaped positive electrode; a belt-shaped negative electrode; a belt-shaped porous layer between the belt-shaped positive electrode and the belt-shaped negative electrode; and an adhesive layer formed on the surface of the belt-shaped porous layer, wherein the adhesive layer includes a fluorine resin-containing particulate and a binder for an adhesive layer supporting the fluorine resin-containing particulate, the binder comprising at least one of an ionic non-water-soluble binder, a non-ionic water-soluble binder, a non-ionic non-water-soluble binder and an ionic water-soluble binder.
