电极构造体及其制造方法和电池及其制造方法
摘要：
本发明提供了一种电极，能够抑制电学性能的变动从而稳定电池性能和提高产品良率。本发明提供的一种电极构造体包括：包括集电体和设置在集电体上的活性材料层的电极；和设置在活性材料层上的电极引线，其中一个孔贯穿电极和电极引线，并且电极和电极引线在该孔周围向离开该孔的方向折回使得电极被置于内侧，并且在未设置电极引线的区域的活性材料层的厚度是均一的，在设置电极引线的区域的活性材料层的厚度是不均一的。
摘要（英）：

An electrode capable of preventing variations in electrical performance to stabilize performance and improve yields is provided. An electrode structure includes: an electrode including an current collector and an active material layer arranged on the current collector; and an electrode lead arranged on the active material layer, wherein a hole is arranged so as to penetrate the electrode and the electrode lead, and the electrode and the electrode lead are folded back around the hole in a direction away from the hole so that the electrode is placed inside, and the thickness of the active material layer in a region where the electrode lead is not arranged is uniform, and the thickness of the active material layer in a region where the electrode lead is arranged is nonuniform.
