A heat-activated fire-suppression system is provided. The system can include one or modules installed in an exterior panel of a building. The one or more modules can include a shape memory alloy wire that deforms upon heating to cause the module to release a pressurized substance. The system can include an alarm module that emits an auditory alarm. The system can include a fire-suppression module that releases a fire-suppressing substance upon the shape memory wire deforming in response to heating.

A battery pack includes a battery pack case configured to receive one or more battery modules and a heat sink located above the battery modules, wherein each of the battery modules includes a plurality of battery cells, a water tank located above the plurality of battery cells, and a module case configured to receive the plurality of battery cells and the water tank, whereby, when fire breaks out in the battery cell, it is possible to rapidly and accurately prevent spread of flames of the ignited battery cell.

A battery pack includes a battery module housing configured to receive a plurality of battery cells, a battery pack case configured to receive one or more battery module housings, a water tank located above the battery module housings, and a heat sink located under the battery module housings. The battery module housing is configured to wrap the plurality of battery cells. In a battery pack including a plurality of battery modules, it is possible to prevent thermal spread between adjacent battery modules when fire breaks out in a battery cell.

Embodiments of the present application provide a battery, a power consumption device, and a method and device for producing a battery. The battery includes: a battery cell, the battery cell including a pressure relief mechanism configured to be actuated when an internal pressure or temperature of the battery cell reaches a threshold, to relieve the internal pressure; a fire-fighting pipeline configured to accommodate a fire-fighting medium and discharge the fire-fighting medium toward the battery cell when the pressure relief mechanism is actuated; and an accommodating part configured to accommodate the fire-fighting medium discharged from the fire-fighting pipeline to lower a temperature of the battery cell. According to technical solutions of the embodiments of the present application, the safety of the battery could be enhanced.

Embodiments of the present application relates to a battery, a power consumption device, and a method and device for producing a battery. The battery includes: a battery cell, the battery cell including a pressure relief mechanism; a fire-fighting pipeline configured to accommodate a fire-fighting medium, the fire-fighting pipeline including a first region corresponding to the pressure relief mechanism and a second region located at a periphery of the first region, the first region being configured to be damaged when the pressure relief mechanism is actuated, such that the fire-fighting medium is discharged; and a protective component disposed between the fire-fighting pipeline and the battery cell and configured to protect the second region. The battery, the power consumption device, and the method and device for producing the battery in the embodiments of the present application could improve the safety performance of the battery.

Fire protection and suppression apparatus, materials, systems, and methods of use thereof are disclosed. In fire extinguishing applications, aerosol extinguishing agent in sheets, panels or other forms can be placed in a variety of implementations, including one or more of, but not limited to, inside an enclosure that contains a fire hazard, in an interior of a fire hazard itself, incorporated into a structure of a fire hazard. Once initiated, the aerosol extinguishing material will burn to create and directly disperse the aerosol particulate that can extinguish the fire. Initiation of the aerosol agent can be by flames or heat from an unwanted fire. Alternative methods of initiation include electric initiators that are signaled by automatic fire detection systems, electric manual methods, or mechanical/thermal initiators.
