用于非水电解质可再充电电池的电极卷绕元件、其制备方法、和非水电解质可再充电电池
Abstract:
本发明涉及非水电解质用于可再充电电池的电极卷绕元件、其制备方法、和非水电解质可再充电电池。用于非水电解质可再充电电池的电极卷绕元件包括：带状正极；带状负极；在所述带状正极和所述带状负极之间的带状多孔层；和形成于所述带状多孔层的表面上的粘附层，其中所述粘附层包括包含氟树脂的微粒和支持所述包含氟树脂的微粒的用于粘附层的粘合剂，所述粘合剂包括离子型非水溶性粘合剂、非离子型水溶性粘合剂、非离子型非水溶性粘合剂和离子型水溶性粘合剂的至少一种。
Abstract(English):

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.
