- a plurality of the cells may be arranged inside the housing, and the fire extinguishing sheet may cover the upper surfaces of the cells and also cover the side surfaces around the cells.
- the fire extinguishing sheet may be attached to the upper surface inside the housing and the inner surface of the side surface of the housing.
- One aspect of the present invention provides a battery package comprising a rack and the plurality of battery modules described above arranged in the rack.
- the rack may have a lid, a fire-extinguishing sheet may be placed inside the lid, and the fire-extinguishing sheet may be placed above the unit cells in the housing across a plurality of modules.
- FIG. 1 is a perspective view (A) and a cross-sectional view (B) taken along the line AA schematically showing an example of the configuration of a battery module according to an embodiment of the present disclosure
- FIG. 1 is a perspective view schematically showing an example of a battery package in which a plurality of battery modules of the present disclosure are mounted
- FIG. 1A and 1B are a perspective view (A) and a cross-sectional view (B) taken along the line BB, schematically showing an example of the configuration of a conventional battery module.
- FIG. 1 is a perspective view schematically showing an example of a battery module according to an embodiment of the present disclosure.
- a battery module 10 of the present disclosure has eight cells 1 arranged inside a housing 2 .
- a fire extinguishing sheet 4 is placed on the upper side of the cell 1 .
- the fire extinguishing sheet 4 is, for example, a sheet material kneaded with a fire extinguishing agent. Specifically, the fire extinguishing sheet 4 is kneaded with an amount of fire extinguishing agent necessary for extinguishing the fire of the ignited cell 1 .
- the fire extinguishing sheet 4 is preferably thin. The thinner the fire extinguishing sheet 4, the smaller the size of the package.
- the space 3 is provided above the single cell 1 .
- This space 3 has been an obstacle to miniaturization.
- such a space is not provided, and miniaturization is achieved by adopting a thinner fire extinguishing sheet 4 (see FIG. 1).
- FIG. 2 is a perspective view showing an example of a battery package 100 in which a plurality of battery modules 10 of the present disclosure are mounted.
- battery package 100 has rack 5 .
- a rack 5 houses a plurality of battery modules 10 .
- a large number of battery modules 10 are usually housed in a narrow space. Therefore, if one module catches fire, the fire may spread.
- the battery module 10 has the fire extinguishing sheet 4 as described above. Therefore, when the unit cell 1 catches fire, the fire extinguishing agent of the fire extinguishing sheet 4 melts out and extinguishes the fire. Therefore, the spread of fire to other battery modules 10 can be suppressed.
- the fire extinguishing sheet 4 may be placed on the cell 1.
- the fire extinguishing sheet 4 may be attached to the inside of the top cover (not shown).
- An upper lid is provided on the rack 5 as an example.
- the fire extinguishing sheet 4 may cover multiple modules 10 .
- a top cover to which the fire extinguishing sheet 4 is attached may cover the modules 10 . That is, the fire extinguishing sheet 4 may be arranged not only on a single module but also on a package of a plurality of modules.
- the form of the battery package 100 is not limited to the illustrated one, and may be another form.
- a package in which the modules are arranged vertically as shown in FIG. 2 is preferable.
- a plurality of battery modules 10 may be arranged in the horizontal direction and the battery modules 10 may be connected to each other.
- Such an assembled battery may be provided in the floor portion of the vehicle body.
- the fire extinguishing sheet 4 may cover not only the upper surface side of the cell but also the side surfaces (front side, rear side, left side, right side). This configuration also has the desired effect and is useful. In addition to square packages, there are also cylindrical and pouch packages.
- the module of the present disclosure and its package can also be applied to a configuration of a cylindrical or pouch type package. There may be a gap (space) between the fire extinguishing sheet on the upper surface side or the side surface side of the unit cell 1 and the unit cell. Another functional sheet or the like may be interposed between the cell 1 and the fire extinguishing sheet 4 .
- the cell 1 used in the present disclosure may be a secondary battery or a primary battery. From the standpoint of susceptibility to ignition, the present invention is more effective due to the configuration using a secondary battery. Any secondary battery may be used.
- the secondary battery may be a lithium-ion battery, a nickel-cadmium battery, a nickel-hydrogen battery, a sodium-sulfur battery, or the like.
- the structure of the cell 1 is not particularly limited, as an example, the cell 1 has a negative electrode active material arranged on one side and a positive electrode active material arranged on the other side, and both are separated by a solid electrolyte (not shown). It may be a structure. Solid electrolytes are selectively permeable to ions such as lithium ions or sodium ions. Charging and discharging are performed by the movement of the ions on the walls of the solid electrolyte.
- the extinguishing agent may be, for example, sodium hydrogen carbonate, potassium hydrogen carbonate, phosphoric acid compounds (ammonium dihydrogen phosphate), a combination of potassium hydrogen carbonate and urea, and the like.
- the fire extinguishing sheet 4 kneaded with a potassium compound or a sodium compound is preferred, and the fire extinguishing sheet 4 kneaded with a potassium compound is more preferred.
- the fire extinguishing sheet 4 is arranged so as to be in direct contact with the cell 1 .
- Other functional sheets or the like may be placed between the cell 1 and the fire extinguishing sheet 4 as necessary.
- the fire extinguishing sheet 4 is arranged on the unit cells 1 arranged in each battery module 10 . Therefore, even if a fire breaks out in any module, it is possible to prevent the fire from spreading to other modules. Therefore, even in the unlikely event of a fire, the fire will be contained inside the module, and there is no risk of a large-scale fire.
- the fire is immediately extinguished by the fire extinguishing agent, thus enhancing safety.
- the size of the housing 2 is smaller than that of the conventional one that requires a space 3, and the volumetric energy density is increased. That is, according to the battery module of the present disclosure, both high safety and high volumetric energy density can be achieved.
- the fire extinguishing sheet 4 may cover only part of the upper surfaces of the plurality of cells 1 instead of all of them, as shown in FIG. Passages through which gas or smoke flows are formed in areas inside the housing 2 where the fire extinguishing sheet 4 does not cover the upper surfaces of the plurality of cells 1 (areas on the right and left sides of the fire extinguishing sheet 4 in FIG. 1). may
- the fire extinguishing sheet 4 may be arranged so as to cover the upper surfaces of the plurality of unit cells 1 and also cover the side surfaces around the plurality of unit cells 1 .
- the fire extinguishing sheet 4 may be attached to any member, but may be attached to the upper surface inside the housing 2 and the inner surface of the side surface of the housing 2, for example.
