摘要： A battery cell closure strip for a battery cell of prismatic or of pouch-type design is disclosed. A main body has a degassing duct which extends along the vertical axis of the battery cell closure strip from an inner side of the battery cell closure strip to the outer side of the battery cell closure strip. The degassing duct is closed by means of a media-operated sealing element during regular operation of the battery cell closure strip. The sealing element opens the degassing duct when a predefined limit pressure of the battery cell is reached. An emergency degassing duct has an opening cross section through which media can flow that is at least 10 times larger than that of the degassing duct and which is closed by a bursting valve which opens the emergency degassing duct when a bursting pressure is reached or exceeded.

摘要： A battery includes a battery cell body and a packaging housing. An edge of the packaging housing has an edge banding. The edge banding has a cross section cut along a thickness direction of the edge banding. The edge banding extends upwardly along a side surface of the battery cell body. A side surface, close to battery cell body, of the edge banding is an inner side surface. A side surface, away from battery cell body, of the edge banding is an outer side surface. A first bonding body is disposed on the cross section. The first bonding body wraps the cross section, a part of the inner side surface, and a part of the outer side surface. A thickness L1 of the first bonding body on the inner side surface is greater than a thickness L2 of the first bonding body on the outer side surface.
