A method of manufacturing a battery includes introducing a first material to the battery, providing an anode, a cathode and a separator of the battery; and assembling the anode, the separator and the cathode. The first material is configured and arranged to increase the internal impedance of the battery upon mechanical or thermal loading.

Aspects relate to systems and methods of use for a crash safe battery pack that includes a case, a first battery module located within the case and mounted to the case with at least a breakaway mount, a second battery module located within the case, a frangible connection configured to provide electrical conduction between the first battery module and the second battery module, and a die configured to contact and separate the frangible connection when the crash safe battery pack is impacted with a sufficiently great connection breaking force.

Disclosed is a battery cell having an electrode tab with an enhanced safety, and a battery module, a battery pack and a vehicle including the same. The battery cell includes an electrode assembly including a cell body and an electrode tab provided to at least one of both sides of the cell body, a cell case configured to accommodate the electrode assembly therein, an electrode lead drawn out of the cell case by a predetermined length and connected to the electrode assembly through the electrode tab, and a tab protection module accommodated in the cell case and configured to cover at least a part of the electrode tab.

A thin film battery package includes: a case having an open top side and defining a predetermined space therein, wherein the case has one side at which first and second electrodes formed of a metal material are exposed and electrically connected to the outside; a battery block on which a plurality of unit batteries are stacked so that the plurality of unit batteries is electrically connected between a first terminal and a second terminal, wherein the battery block is seated within the case so that the first and second terminals of the unit battery disposed at one end thereof are electrically connected to the first and second electrodes; and a cover sealed and coupled to the top surface of the case.

A battery management system for a battery module having at least one battery cell provides a current path between poles of the battery module in response to a tripping signal. The current path prevents or terminates an arc in a fuse of the at least one battery cell after the fuse has been tripped. The battery management system can further include an apparatus to trip the fuse and provide the tripping signal in response to identifying the tripping of the at least one fuse. The battery management system can further include an apparatus to receive the tripping signal.

Provided are a secondary battery, a battery module, and a battery pack, which have improved safety. Particularly, since a bulletproof material is disposed on the inside and/or the outside of an exterior part, even when a conductive needle-shaped member penetrates a secondary battery, heating, burning, discharge of evaporated electrolyte, and electrical contact between the needle-shaped member and an electrode can be prevented, thereby improving safety of the secondary battery, the battery module, and the battery pack.

A humidifier block and a method for producing a humidifier block are disclosed. The humidifier block may include a plurality of membranes each having a cavity for passing a through-flow and a jacket surrounding the cavity in a circumferential direction. The jacket may be moisture-permeable. At least one strip-shaped carrier may be fitted with the plurality of membranes, and the plurality of membranes may arranged in a longitudinal direction parallel to one another and adjacent to one another on the at least one carrier. The at least one carrier fitted with the plurality of membranes may be shaped into the humidifier block such that the plurality of membranes are arranged adjacent to one another in a transverse direction running transversely to the longitudinal direction and adjacent in a height direction running transversely to the longitudinal direction and transversely to the transverse direction.

A current interrupt device, which may be included in a battery module, includes first and second connection parts each having one surface on which an inclined surface is formed; wherein the inclined surface of the first connection part and the inclined surface of the second connection part contact each other to form a contact interface, the first connection part and the second connection part are electrically connected to each other, and when an external force equal to or greater than a predetermined force is applied to the inclined surface of the first connection part or the inclined surface of the second connection part, the inclined surface of the first connection part and the inclined surface of the second connection part are dislocated with respect to each other on the contact interface to interrupt electrical connection between the first connection part and the second connection part.

Provided is a thin film battery module. The thin film battery module comprises: a battery module which is configured of unit cells stacked against each other; and a shock absorbing portion which surrounds the space between the unit cells and the battery module. Also provided are a thin film battery package, a thin film battery package manufacturing device, and a thin film battery package manufacturing method.
