The invention provides an electrode assembly, a cylindrical battery cell, a battery pack, and a vehicle. An electrode assembly according to an embodiment of the present disclosure is a winding core type having a structure in which a first electrode and a second electrode each having a sheet shape and a separator interposed between the first electrode and the second electrode are wound in one direction. Each of the first electrode and the second electrode includes: an uncoated portion not coated with an active material layer and formed on a longer edge end portion; and a coated portion coated with the active material layer and formed on a region other than the uncoated portion. The first electrode includes at least one insulating layer simultaneously covering at least a portion of the uncoated portion and at least a portion of the coated portion.

    本发明提供电极组件、圆柱形电池单元、电池组和车辆。根据本公开的实施方式的电极组件是具有如下结构的卷芯型,在该结构中,在一个方向上卷绕均具有片材形状的第一电极和第二电极以及插设在所述第一电极和所述第二电极之间的隔膜。所述第一电极和所述第二电极中的每一者均包括:未涂覆有活性材料层并且形成在较长的边缘端部上的未涂覆部分;以及涂覆部分,所述涂覆部分涂覆有活性材料层并且形成在除所述未涂覆部分之外的区域上。所述第一电极包括同时覆盖所述未涂覆部分的至少一部分和所述涂覆部分的至少一部分的至少一个绝缘层。
