A battery module with high impact resistance is provided. A battery module using an elastic body such as rubber for its exterior body covering a battery is provided. A bendable battery module is provided. As the exterior body covering a battery, an elastic body such as rubber is used, and the exterior body is molded in two steps. First, a first portion provided with a depression in which a battery is stored is molded using a first mold. Next, a battery is inserted into the first portion. Subsequently, second molding is performed using a second mold so as to fill an opening of the depression in the first portion, so that a second portion is formed. The second portion serves as a cover for closing the opening of the depression in the first portion. The second portion is formed in contact with part of the electrodes in the battery and part of an end portion of the second exterior body in the battery.

Disclosed herein is a method of manufacturing a battery pack including a battery cell having an electrode assembly received in a battery case, made of a laminate sheet including a resin layer and a metal layer, together with an electrolytic solution.

An energy storage component (ESC) enclosure is provided. The ESC enclosure includes a plurality of ESC modules. Each ESC module includes at least one side portion having a plurality of side fastening mechanisms configured to be coupled to an adjacent ESC module, wherein the plurality of ESC modules is coupled together via the plurality of side fastening mechanisms to form an ESC enclosure. The ESC enclosure further includes a plurality of shelving kits, each shelving kit mounted to one of the ESC modules. The ESC enclosure further includes a roof that is coupled to the plurality of ESC modules, and a plurality of panels coupled to the plurality of ESC modules about a perimeter of the ESC enclosure to form a shared air space within the ESC enclosure.

The invention relates to a power storage module (10) capable of containing a plurality of power storage elements (14), the module including: a housing (16) including at least a plurality of side walls and two end walls (18A; 18B), the side walls consisting of one piece (20) having a closed outline and being sized so as to surround the power storage elements; a wall (22) for supporting the power storage elements, which is separate from the walls of the housing, and which extends essentially parallel to one of the side walls, referred to as a reference wall (20A); a means (24A-24B) for changing the position of the supporting wall (22) between at least an assembly position, in which the supporting wall is located at a first distance from the reference wall (20A), and an operating position, in which the supporting wall is located at a second distance from the reference wall (20A) that is greater than the first distance.

An electrode assembly and a secondary battery having an electrode tab are disclosed. In one aspect, the electrode assembly includes first and second electrodes which are wound with a separator placed therebetween. The first electrode includes a first coated portion, and a plurality of first electrode tabs T1-Tn not coated with an active material and protruding outwardly from the first coated portion, wherein n is greater than 2. The first electrode, when spread in a plane form, includes first to nth portions on which the first electrode tabs T1-Tn are respectively formed, wherein the first and nth portions respectively define the innermost and outermost portions thereof. The distance between the first electrode tab Tn placed at the outermost portion and the first electrode Tn−1 placed at the second outermost portion is greater than any of the distances between two adjacent ones of the other first electrode tabs T1-Tn−1.

Embodiments include a portable rechargeable battery pack, system, and external adapter that allow the portable rechargeable battery pack to both power a host device though a set of host contacts and provide power through a set of charging contacts. The portable rechargeable battery pack includes a charge protection circuit that prevents an excessive discharge current through the charging contacts and allows high charge current when charging the portable rechargeable battery pack. A discharge circuit allows a low level discharge current through the charging contacts to provide power to other devices.

An apparatus includes a plurality of battery cells and a case. The case may be configured to hold the plurality of battery cells. The case generally has at least a first port and a second port configured to allow a cooling liquid to flow through the case with the battery cells submerged in the cooling liquid. The case is generally configured to interlock with one or more other cases to electrically and physically connect the one or more cases into a battery block or battery pack.

A flexible lithium battery includes a flexible pouch and two conductive tabs. The flexible pouch has an accommodating space and a being sealed side, and the two conductive tabs are inserted in the being sealed side and extended to the accommodating space. The being sealed side includes a first sealing area and a second sealing area, the first sealing area and the second sealing area are sealed to form a side seal through a combination means. The first sealing area has a first binding force, and the second sealing area has a second binding force. The second binding force is smaller than the first binding force, and gas accumulated in the accommodating space is discharged from the second sealing area.
