The ceiling surface (24) includes an exposed area (35) that is not covered with the insulating sheet (31). The insulating sheet (31) includes a projecting portion (34) projecting downward. The projecting portion (34) is disposed between the stack (10) and the exposed area (35) in plan view.

A container system (1) arranged for storing and/or transporting a rechargeable battery (2), such as a lithium-ion battery, wherein said container system (1) comprises a supporting assembly (31) arranged for supporting said container system on a ground surface and comprising a support surface arranged for supporting said rechargeable battery (2), a covering assembly (35), removably attachable to said supporting assembly (31), provided with a receiving space (7) arranged for receiving, via a receiving opening (5) of said covering assembly (35), said rechargeable battery (2) and a method (100) of storing and/or transporting a rechargeable battery, such as a lithium-ion battery , wherein said side wall arrangement (9) is provided with a through hole (11) and a filtering arrangement (13). A method (100) of storing and/or transporting a rechargeable battery (2).

Disclosed is a battery cell, which includes a battery case having an accommodation portion in which an electrode assembly is mounted, and a sealing portion formed by sealing an outer periphery thereof; an electrode lead electrically connected to an electrode tab included in the electrode assembly and protruding out of the battery case via the sealing portion; and a lead film located at a portion corresponding to the sealing portion in at least one of an upper portion and a lower portion of the electrode lead, wherein a gas discharge guiding unit is inserted in the lead film, the sealing portion includes a first sealing portion located on the gas discharge guiding unit and a second sealing portion located at both sides of the first sealing portion, and based on a protruding direction of the electrode lead, a width of the first sealing portion is smaller than a width of the second sealing portion.

A battery pack includes a bottom plate (110), a first beam, (120) a frame (130), and a battery assembly (140) having at least two batteries (141). A height of the frame (130) is greater than a height of the first beam (120), the height of the first beam (120) is a distance between a side of the first beam (120) away from the bottom plate (110) and the bottom plate (110), and the height of the frame (130) is a distance between a side of the frame (130) away from the bottom plate (110) and the bottom plate (110). The battery assembly (140) is disposed at an accommodating portion between the frame (130) and the first beam (120), and has a first end and provided with a first explosion-proof valve (142), and a second end provided with a second explosion-proof valve (143). A distance from the second explosion-proof valve (143) to the bottom plate (110) is greater than that from the first explosion-proof valve (142) to the bottom plate (110).
