摘要： Disclosed herein is a jelly-roll type electrode assembly (“jelly-roll”) of a cathode/separator/anode structure, wherein the jelly-roll is constructed in a structure in which each electrode has active material layers formed on opposite major surfaces of a sheet-type current collector, the loading amount of an active material for the inner active material layer, constituting the inner surface of each sheet when each sheet is wound, is less than that of an active material for the outer active material layer, constituting the outer surface of each sheet when each sheet is wound, and the loading amount of the active material for the inner active material layer gradually increases from the central region of each wound sheet to the outermost region of each wound sheet.

摘要翻译： 本文公开了阴极/分离器/阳极结构的胶卷式电极组件（“胶卷”），其中胶卷被构造成其中每个电极具有形成在相对主表面上的活性材料层的结构 构成片材每个片材的内表面的构成内部活性物质层的活性物质的负载量小于外部活性物质层的活性物质的负载量，构成 每个片材被卷绕时的每个片材的外表面，并且用于内部活性材料层的活性材料的负载量从每个缠绕片材的中心区域逐渐增加到每个缠绕片材的最外部区域。
