摘要： Disclosed is a rechargeable battery for preventing a short circuit of a cell by inducing bending of a case under compression. The rechargeable battery comprises a case comprising a bottom portion and front and rear portions connected to the bottom portion by joint portions including internal curved surfaces, an electrode assembly in the case and a cap assembly closing the case, wherein the curved surfaces define a first portion A1 in a centre portion of the case and second portions A2 on either side of the first portion, wherein the second portions have a higher mechanical strength than the first portion with respect to a compression force applied to the sides of the case.

摘要： A battery pack comprises a first battery cell and a second battery cell; the first and second battery cells each have a size within a manufacturing tolerance. A housing comprises at least one wall defining a first hole and a second hole each for receiving one of the first or second battery cells, each hole having a size corresponding to a minimum size within the manufacturing tolerance. There is a flexibly resilient portion moveable between a rest position and a clamping position whereby the flexibly resilient portion clamps against the first and / or second battery cell when the first and / or second battery cell has a size greater than the minimum size within the manufacturing tolerance.

摘要： A pouch cell includes a generally rectangular cell housing formed of a metal laminated film that includes a box portion and a lid portion that is formed separately from the box portion. The active material including the electrode and an electrolyte is placed into the box portion and the lid portion is welded to the box portion. The box portion and the lid portion are formed and assembled together without using a drawing or a punching process. Instead, the pouch cell housing is formed via a series of folding and welding steps, whereby the pouch cell size is not limited by the draw depth of the metal laminated film.

摘要： A lithium-ion secondary-battery case that allows bonding without weld spatter and has high strength against external force acting on the battery case, and a method for manufacturing the lithium-ion secondary-battery case are provided. Specifically, an austenitic stainless steel foil is used for a cup component (2), and a two-phase stainless steel having an austenite transformation start temperature A C1 in a temperature increase process at 650°C to 950°C and an austenite and ferrite two-phase temperature range of 880°C and higher , is used for a cover component (3), and the diffusion bonding is proceeded while accompanied by grain boundary movement upon transformation of the two-phase steel from a ferrite phase into an austenite phase within a heating temperature range of 880°C to 1080°C.

摘要： The battery case (110) of this square battery (100) comprises a lid member (113) welded to an opening (111h) in a main body member (111). The opening R section (111r) of the opening (111h) has, in the circumferential direction (SH), a support projection (111e) which projects inwards across the entire opening R section (111r) and which supports the lid member (113). Meanwhile, in the circumferential direction (SH) across the entire opening short side (111b), the opening short side (111b) has a low projecting section (111d) which projects inwards at a position lower than the support projection (111e) in the depth direction (FH) of the main body member (111).
