The present disclosure relates to a sheath material for secondary battery including a moisture permeation preventing layer, a protective layer disposed on the first surface of the moisture permeation preventing layer wherein the protective layer includes a functional layer having a plurality of patterns and a resin layer disposed on the second surface of the moisture permeation preventing layer, and a secondary battery including the same.

A battery capable of changing its form safely is provided. A bendable battery having a larger thickness is provided. A battery with increased capacity is provided. For an exterior body of the battery, a film in the shape of a periodic wave in one direction is used. A space is provided in an area surrounded by the exterior body and between an end portion of the electrode stack that is not fixed and an interior wall of the exterior body. Furthermore, the phases of waves of a pair of portions of the exterior body between which the electrode stack is located are different from each other. In particular, the phases are different from each other by 180 degrees so that wave crest lines overlap with each other and wave trough lines overlap with each other.

A cooling arrangement for cooling at least one first and/or second battery module of a high-voltage battery for a motor vehicle. The cooling arrangement has a line arrangement which includes a feed connection, a first and second opening respectively associated with the first and second battery module, and which is designed as branched, so that a cooling medium provided at the feed connection can be led via a first line branch to the first outlet opening and via a second line branch to the second outlet opening and can be led selectively out of the first outlet opening or the second outlet opening.

A battery pack protects the internal battery pack components from the heat, e.g., heat generated during a sterilization process of an autoclave. The battery pack prevents the heat of the autoclave from damaging the battery cells and other electronic components within a battery pack housing. The battery pack may include a multi-layer thermal protection portion lining an inside surface of the walls of the battery pack housing with a combination of materials designed to limit the amount of heat to which the internal components of the battery will be exposed for the duration of a traditional autoclave sterilization cycle. Additionally, the battery pack may include a thermal protection casing around connection elements, such as wires and contacts, between a battery pack contact and the battery cells, to limit the heat rise from the heat of the autoclave in or on the connection elements of the battery pack.

An electrochemical cell module includes a plurality of electrochemical cells stacked on one another and each including an electricity generator and a casing, and a housing accommodating the plurality of electrochemical cells. The casing includes a peripheral portion without overlapping the electricity generator as viewed in the stacking direction. The peripheral portion is bent and has its main surface in contact with an inner side surface of the housing.
