The invention relates to the field of A lithium ion battery and discloses a buckle-type lithium ion battery case and a buckle-type laminated lithium ion battery. The case comprises a first pole case.A first end cover is arranged at one end of an annular shape formed by a first annular shell piece, and the other end is an annular opening. A second pole shell provided with a second end cover at oneend of the annular shape formed by the second annular shell sheet and an annular opening at the other end; Insulating sealing ring, A second annular shell is sleeved over the first annular insulator,Between that second annular insulator, The first pole shell and the second pole shell are oppositely sleeved to form a sealed cavity, the first annular shell segment covers the second annular insulator, the annular opening of the second annular shell wrapped by the insulating sealing ring abuts on the inner wall of the first pole shell, and the insulating sealing ring is in an elastic deformationstate under the action of the first pole shell and the second pole shell. The application of the scheme is favorable for improving the capacity of the button battery.
