[0057] As shown in FIGS. 1 and 2, a battery storage container (10) according to one embodiment of the present invention having a rope-type discharge portion may largely include a cover portion (100), a main body portion (200), and a discharge portion (300b).

[0058] Here, in order to more easily explain the arrangement of the emission unit (300b), FIG. 2, FIG. 4 to be described later, and FIG. 5 to be described later, only the frame of the cover unit (100) is shown so that the sealed space in which the first space of the cover unit (100) and the second space of the main body unit (200) are merged can be confirmed.

[0059] As shown in the drawing, the cover part (100) may have a first space formed therein, and the first space may be provided to face the second space of the main body part (200) to be described later.

[0060] The main body (200) has a second space formed therein for accommodating a battery, and can be combined with the cover part (100) described above to form a sealed space in which the first space and the second space are combined.

[0061] In other words, the cover part (100) and the main body part (200) each have an internal space, and a battery can be accommodated in the space of the main body part (200), and then a cover can be placed on top of the cover part (100) to seal the internal space.

[0062] At this time, the main body (200) can form a space for accommodating a battery by combining multiple banded iron plates to strengthen the internal sealing force, thereby minimizing the area where multiple plates are combined by welding or fastening.

[0063] For example, the first and second iron plates can be bent into a “ㄷ” shape to form the bottom and side surfaces in the same shape.

[0064] Here, when the bottom surface of the first steel plate that has been folded is placed on the ground, a portion of the side facing the top of the first steel plate becomes open. At this time, when the bottom surface of the second steel plate is placed on the bottom surface of the first steel plate so that a portion of the closed side of the second steel plate that has been folded in the same shape is positioned on the open side of the first steel plate, and when the two plates are joined by welding or fastening, a main body (200) with an open top can be formed.

[0065] Finally, the gap at the corner can be welded or fastened with a frame to form a second space.

[0066] Additionally, a space may be provided on the outer lower part of the main body (200) so that the battery storage container can be stably hung on a transport means such as a forklift or other transport vehicle, so that the transport vehicle can stably transport the battery storage container.

[0067] The cover part (100) can also be formed by combining multiple banded iron plates with the main body part (200) to form a first space.

[0068] Here, the discharge unit (300b) discharges the extinguishing agent (310b) into a sealed space in which the first space and the second space described above are combined, and the discharge unit (300b) can discharge the extinguishing agent (310b) into the sealed space when the preset temperature is reached.

[0069] For example, in order to quickly extinguish a fire, it would be desirable for the discharge unit (300b) to extinguish the fire by discharging the fire extinguishing agent (310b) located inside the receiving member (320b) into a closed space within a few seconds through the micro-holes (321ba) formed in the receiving member (320b) when the internal temperature of the battery reaches the design temperature.

[0070] This emission section (300b) may be formed in the shape of a long rope in one direction and may be provided along the perimeter of the sealed space.

[0071] When the discharge unit (300b) is provided along the side perimeter of the sealed space, it can be provided on the inner surface of the main body (200) so as to have a preset height from the floor surface of the sealed space, as shown in the aforementioned Fig. 1.

[0072] The preset height at this time may vary depending on various environments or the type of battery being accepted.

[0073] In addition, the batteries may be arranged in a puzzle-like shape inside the sealed space or may be stacked in multiple layers to correspond to the stacking method of the batteries inside the sealed space, but by arranging them higher than the height of the upper surface of the batteries accommodated in the main body (200) by a preset interval based on the lowest surface of the sealed space, that is, the floor surface, the speed at which the fire extinguishing agent (310) released when a fire occurs reaches the batteries and the amount of the fire extinguishing agent (310b) reaching them can be improved.

[0074] At this time, the preset height may be equal to or greater than the height from the bottom surface of the second space of the main body (200) to the top surface of the battery (B), and may be equal to or less than the maximum height of the second space of the main body (200).

[0075] Therefore, as shown in the drawing, when the fire extinguishing agent (310b) is discharged through the discharge portion (300b) provided around the side of the sealed space, the fire extinguishing agent can quickly cover the entire battery and extinguish the fire.

[0076] Also, although not shown in the drawing, the preset height may be a height lower than the height at which the lower surface of the battery (B) is located based on the second space floor surface of the main body (200).

[0077] Therefore, if a fire breaks out at the bottom of the battery (B), the fire can be quickly extinguished.

[0078] For example, the lower surface of the battery (B) can be fixed to a stand that protrudes at a predetermined height from the bottom surface of the second space of the main body (200).

[0079] At this time, the ratio of the height of the pedestal and the total height of the second space described above may be 1:5.5.

[0080] And the height ratio of the above-mentioned pedestal and the height of the battery can be in the range of 1:3.8 to 1:3.9.

[0081] As described above, the discharge unit (300b) is provided at a height where the lower surface of the battery (B) is located in the second space, so that even if a fire occurs at the lower surface of the battery, the fire extinguishing agent (310b) can be quickly discharged between the bottom surface of the sealed space and the lower surface of the battery.

[0082] The above-described discharge unit (300b) can increase the amount of extinguishing agent (310b) directed toward the battery by arranging a plurality of unit members provided along the inner circumference of the main body (200) at regular intervals on the inner surface of the main body (200) as shown in FIG. 2.

[0083] For example, in the case where a plurality of unit members provided along the inner circumference of the main body (200) are arranged at regular intervals on the inner surface of the main body (200), one unit member is provided at a first height that is lower than the height at which the lower surface of the battery (B) is located based on the bottom surface of the second space of the main body (200) along the inner circumference of the main body (200), and another unit member is provided above the first height that is higher than the height to the uppermost surface of the battery (B) based on the bottom surface of the second space of the main body (200) and lower than the maximum height of the second space of the main body (200), thereby improving the extinguishing performance relative to the time at which the extinguishing agent is discharged.

[0084] In addition, since the above-described unit members are arranged at regular intervals on the inner surface of the main body (200), the fire extinguishing agent (310b) can reach the battery at regular intervals, thereby improving the extinguishing performance.

[0085] For example, a plurality of unit members may be provided at the first height and the second height, and a plurality of unit members may be arranged at regular intervals between the first height and the second height.

[0086] In addition, as shown in Fig. 4, even if only one unit member is arranged along the inner circumference of the main body (200), the emission section (300b-1) is within the scope of the present invention.

[0087] Furthermore, as illustrated in FIG. 5, at least one discharge unit (300b-2) may be provided on the lower surface of the main body (200) so that the extinguishing agent (310b) is discharged toward the battery accommodated in the main body (200).

[0088] In addition, at least one discharge unit (300b-2) may be provided on one side of the first space of the cover unit (100) so that the extinguishing agent (310) is discharged toward the battery accommodated in the second space.

[0089] For example, the discharge unit (300b-2) can be arranged at a certain interval on the bottom surface of the first space facing the upper surface of the battery accommodated in the main body (200).

[0090] At this time, the emission parts (300b) may be arranged at regular intervals on the lower surface of the main body (200), i.e., the bottom surface of the second space, although not shown in the drawing. At this time, the emission parts (300b) arranged on the bottom surfaces of the first space and the second space may be arranged at the same intervals and may face each other based on the battery, and may be provided along the inner perimeter of the cover part (100).

[0091] Meanwhile, referring to FIG. 6, the discharge unit (300b) may specifically include a receiving member (320b) and an extinguishing agent (310b).

[0092] The receiving member (320b) is made of a flexible rope-shaped vinyl film (321b), and micro-holes (321ba) can be formed on the outer surface of the vinyl film (321b).

[0093] And the digestive agent (310b) is contained in a solid state inside the receiving member (320b), and when the sealed space reaches a preset temperature, it is released into the sealed space through the micro-holes (321a) of the receiving member (320) within a few seconds and can reach the battery.

[0094] The discharge unit (300b) having the above-described configuration may further include a fixing member (340b) for fixing the receiving member (320b) to a preset position in a sealed space, as illustrated in FIG. 7. For example, the fixing member (340b) may have a plurality of through holes (341b) formed in the longitudinal direction so that the extinguishing agent (310b) discharged from the receiving member (320b) can move.

[0095] Furthermore, as illustrated in FIG. 8, the fixing member (340b) may have a rail formed along the longitudinal direction, and the discharge unit (300b) having the above-described configuration may further include an attachment member (350b). For example, the attachment member (350b) is arranged to move along the rail, and the receiving member (320b) is connected to one side of the attachment member (350b), so that a user can easily move and then place the receiving member (320b) from one side to the other side in the longitudinal direction of the fixing member (340b).

[0096] In addition, for ease of maintenance, as shown in Fig. 9, the fixing member (340b) may include a duct (342b) attached to one side of the sealed space, and a cover (344b) fixed to the duct (342b) and having a plurality of holes arranged therein.

[0097] Here, a plurality of through holes (341b) may be formed in the cover (344b), and as shown in FIG. 9, through holes (341ba, 341bb, 341bc) having central axes at different angles with respect to the upper surface of the cover (344b) may be formed.

[0098] In other words, by forming through holes (341ba, 341bb, 341bc) having different angles based on the upper surface of the cover (344b), the angle of emission can be set in various ways, and although not shown in the drawing, each through hole (341a, 341b, 341c) can be opened and closed so that the emission position can be set.

[0099] Furthermore, when the surface to be fixed is curved, the fixing member (340b) can be stably attached by being provided in a shape with a curvature corresponding to the curvature of the surface to be fixed, as shown in FIG. 11, and the fixing member (340b) can also be provided in a flexible structure and arranged to correspond to the shape of the surface to be fixed.

[0100] In addition, the discharge unit (300b) may further include a storage member (360b) for storing a storage member (320b) containing a fire extinguishing agent (310b) as illustrated in FIG. 12, and may be installed at a major ignition point. For example, the storage member (360b) may be positioned in close contact with the lower surface of the battery as illustrated in the drawing.

[0101] At this time, the storage member (360b) may be provided so that at least a portion of the area in contact with the battery has a mesh shape.

[0102] Next, with reference to FIGS. 13 to 18, a battery storage container (20) according to another embodiment of the present invention having a patch-type discharge portion will be described.

[0103] FIG. 13 is a drawing for explaining a discharge portion of a battery storage container according to another embodiment of the present invention, FIG. 14 is a drawing for explaining an example of a battery accommodated in a main body of a battery storage container according to another embodiment of the present invention, FIG. 15 is a drawing for explaining a modified example of a discharge portion of a battery storage container according to another embodiment of the present invention, FIGS. 16 and 17 are drawings for explaining a spacing of discharge portions for batteries in a battery storage container according to another embodiment of the present invention, and FIG. 18 is a drawing for explaining a storage portion of a battery storage container according to another embodiment of the present invention.

[0104] In order to more easily explain the arrangement of the discharge unit (300a), referring to Fig. 13 which shows only the main body (200), a battery storage container (20) according to another embodiment of the present invention may largely include a cover unit (100), a main body (200), and a discharge unit (300a).

[0105] Here, the cover part (100) and the main body part (200) are identical or similar to the cover part (100) and the main body part (200) described above in one embodiment of the present invention, so their description will be omitted and only the other parts will be described.

[0106] The main body (200) having the above-described configuration may additionally include a fixing member (220) so that the battery is accommodated spaced apart from one side of the sealed space, as illustrated in FIG. 13.

[0107] For example, the fixing member (220) may include a lower fixing member (222), an additional fixing member (224), a side fixing member (226), and a central fixing member (228). The lower fixing member (222) is fixed along an edge on the lower surface of the main body (200), and may be provided in a step shape so that the lower surface edge of the battery is secured.

[0108] In other words, the lower fixing member (222) may be arranged to be in contact with a portion of the lower surface and a portion of the side surface of the battery.

[0109] And the additional fixing member (224) can be placed between the lower fixing members (222) as shown in the drawing, and can be provided in a form in which it protrudes upward from the lower surface of the main body (200) and its upper surface completely touches the lower surface of the battery.

[0110] In addition, the side fixing member (226) can fix the side of the battery so that, when multiple batteries are accommodated in a closed space, the batteries can be stably fixed with a gap between each other in the accommodation space.

[0111] In addition, when a side fixing member (226) is provided, the fixing member (220) may further include a central fixing member (228) to assist in maintaining spacing between batteries.

[0112] Additionally, a space may be provided on the outer lower part of the main body (200) so that the battery storage container can be stably hung on a transport means such as a forklift or other transport vehicle, so that the transport vehicle can stably transport the battery storage container.

[0113] As described above, the discharge unit (300a) discharges the extinguishing agent into a sealed space in which the first space and the second space described above are combined, and the discharge unit (300a) can discharge the extinguishing agent into the sealed space when a preset temperature is reached.

[0114] For example, in order to quickly extinguish a fire, it would be desirable for the discharge unit (300a) to extinguish a fire by discharging the fire extinguishing agent located inside the receiving member into a closed space within a few seconds through micro-holes formed in the receiving member when the internal temperature of the battery reaches the design temperature.

[0115] In another embodiment of the present invention, the emission portion (300a) may be formed in a patch shape.

[0116] Specifically, the discharge unit (300a) can be fixed in the form of a patch on at least one side of the above-described sealed space, and the discharge unit (300a) can be fixed on a lower side of the sealed space so that a predetermined distance is provided from the upper side having a flat shape to one side of the battery facing the upper side.

[0117] For example, the emission unit (300a) may include a lower patch (320a) positioned lower than the battery as shown in the aforementioned FIG. 14.

[0118] And, if the emission unit (300a) can have a flat upper surface, it can be said that it falls within the scope of the present invention even if it is changed to the shape of a circular patch (320a-1) as shown in Fig. 13.

[0119] In addition, the emission unit (300a) may include a corner patch (340a) so that it can be placed at the corner of a closed space as shown in FIG. 13, and may also be fixed to the side of the closed space in the form of a side patch (360a).

[0120] And the discharge unit (300a) may be fixed to the upper surface of the sealed space in the form of an upper patch (380a) as shown in FIG. 15, and the discharge unit (300a) fixed to the sealed space in the form of a patch as described above, when the lower surface is fixed to one surface of the sealed space, may be fixed so that a predetermined distance (d) is provided from the upper surface having a flat shape to one surface of the battery facing the upper surface as shown in FIGS. 16 and 17.

[0121] Taking the form of the lower patch (320a) described above as an example, the receiving member of the lower patch (320a) has a surface facing the battery, that is, the upper surface of the receiving member, which is flat, and micro holes can be formed on the outer surface including the opposite surface.

[0122] At this time, the digestive agent is contained in a solid state inside the receiving member of the lower patch (320a), and when the sealed space reaches a preset temperature, it can be released into the sealed space through the micro-holes described above.

[0123] In the case of a metal fire, when a certain temperature is reached during the fire, the internal pressure inside the container increases, causing the container to rupture and releasing the extinguishing agent toward the heat, heat, and flames.

[0124] Since these metal fires, or class D fires, have so many forms and are difficult to extinguish, and the form of the fire varies depending on the characteristics of the battery, the preset interval (d) of the above-described discharge portion (300a) may vary, but as shown in FIG. 17, the preset interval (d) of the discharge portion (300a) may be determined according to the radiation distance and radiation time of the extinguishing agent so that the discharged extinguishing agent can cover the front of the battery.

[0125] In other words, the preset interval (d) of the discharge unit (300a) can be set in consideration of the fluidity and diffusion ability of the fire extinguishing agent, and when the discharge unit (300a) includes both the lower patch (320a) and the upper patch (340a), the preset interval (d) can be set so that the fire extinguishing agent can reach at least the side of the battery.

[0126] Meanwhile, the arrangement of the discharge unit (300a) may vary depending on the arrangement of the batteries housed in the sealed space. For example, in the case where multiple batteries are housed in the sealed space, multiple discharge units (300a) may be provided, and a discharge unit (300a) may be placed for each battery (B).

[0127] Therefore, when there are multiple batteries (B), it is possible to prevent a situation in which the preset distance (d), which is the distance between the batteries (B) and the discharge unit (300a), becomes too far.

[0128] Furthermore, the battery storage container (20) having the configuration described above may further include a storage section (500a) as illustrated in FIG. 18.

[0129] The storage unit (500a) is provided as a polyhedron with at least one open side and is fixed in a sealed space, and a release unit (300a) can be attached to the inner space.

[0130] At this time, the open surface may be provided so that it can be opened and closed, a mesh net may be formed on the open surface, and the discharge unit (300a) may be provided so that it can be attached and detached in a closed space so that it is easy to replace.

[0131] When replacing, it will be easier to maintain if the distance from the inner upper surface of the storage unit (500a) to the upper surface of the discharge unit (300a) is set to the preset distance (d) described above.

[0132] Below, a battery storage container (30) according to another embodiment of the present invention, which includes a sealing portion (1300) in the configuration of a battery storage container (10, 20) according to one embodiment or another embodiment of the present invention described above, will be examined.

[0133] FIG. 19 is a drawing showing the overall appearance of a battery storage container according to another embodiment of the present invention, FIG. 20 is a drawing for explaining the combination of a battery storage container according to another embodiment of the present invention, FIG. 21 is a drawing for explaining the configuration of a sealing part in a battery storage container according to another embodiment of the present invention, and FIG. 22 is a drawing showing a vent member provided between packing members in a battery storage container according to another embodiment of the present invention.

[0134] A battery storage container (30) according to another embodiment of the present invention, which includes the cover portion (100), main body portion (200), and discharge portion (300b or 300a) described above, may further include a sealing portion (1300).

[0135] At this time, the cover part (100) may be formed in a rectangular shape, with a long axis formed and a short axis formed perpendicular thereto, and a hanging member for transporting the battery storage container (30) may be provided on the upper part of the cover part (100).

[0136] As long as the hanger can be stably hung on a transport means such as a forklift's forklift so that the transport vehicle can stably transport the battery storage container (10), its shape and material can be varied, and it is obvious that the scope of the present invention is not limited due to this.

[0137] However, for a more detailed explanation, if the transport vehicle is a forklift, for example, the hook may be bent in a “ㄷ” shape and connected to the upper part of the cover part (100), so that the forklift leg can be inserted between the hook and the upper part of the cover part (100).

[0138] Additionally, the battery described in the present invention may be a rechargeable secondary battery, and may be any one of a lead-acid battery, a nickel-cadmium battery, a nickel-hydrogen battery, and a lithium-ion battery.

[0139] Preferably, the battery referred to in the present invention may be a lithium-ion battery.

[0140] At this time, the hooks can be arranged at preset intervals along the long axis of the cover portion (100). For example, as illustrated in Fig. 19, the long axis can be divided in half, and a plurality of hooks arranged in the direction in which the fork is introduced can be combined in one area, and another plurality of hooks arranged in the direction in which the fork is introduced can be combined in another area as well.

[0141] The main body (200) is provided to accommodate a battery inside as described above, and can be combined with the cover part (100) described above.

[0142] Next, referring to FIGS. 20 and 21, the sealing portion (1300) will be examined in detail as follows.

[0143] The sealing member (1300) may specifically include a packing member (1320) and a vent member (1340).

[0144] The packing member (1320) is provided between the cover part (100) and the main body part (200) as shown in the drawing, and can seal the space between the cover part (100) and the main body part (200).

[0145] The packing member (1320) can be combined with the cover part (100) or the main body part (200), and if it can perform a sealing function, it will be understood that the scope of the present invention is not limited by being combined with either the cover part (100) or the main body part (200).

[0146] However, for a more detailed explanation, referring to FIG. 22, the packing member (1320) includes a plurality of unit packings arranged at preset intervals along the lower surface edge of the cover part (100), and the vent member (1340) can be arranged between adjacent unit packings.

[0147] At this time, the packing member (1320) may be made of a material such as Teflon and may be provided to have high tensile strength and elasticity and to withstand a compressive load between the cover part (100) and the main body part (200).

[0148] In addition, the packing member (1320) is formed higher than the vent member (1340) based on the surface that is coupled to the cover member (100) or the main body member (200), so that even if compressed by the cover member (100) and the main body member (200), the load of the cover member (100) or the main body member (200) may not be transferred to the vent member (1340).

[0149] The vent member (1340) can discharge air to the outside when the internal pressure of the space where the battery is accommodated exceeds a preset pressure.

[0150] As described above, the vent member (1340) is provided between the packing members (1320), and a path narrowing in one direction can be formed. For example, the vent member (1340) can be provided in a form in which the width narrows from the outlet to the inlet by forming an inclined surface.

[0151] At this time, the vent member (1340) may be arranged to open according to preset conditions while at least one of the inlet and outlet is closed, and the preset conditions may be the internal pressure of the main body (200) in which the battery is accommodated.

[0152] The sealing portion (1300) may be provided to open under a preset pressure condition as described above, or alternatively, the sealing portion (1300) may be provided to open according to the user's selection while the flow path is sealed.

[0153] For example, the sealing member (1300) may further include a pressure member that opens the inlet port in a sealed state according to an electrical signal, and may be provided with a button electrically connected to the main body (200) or cover (100), so that the user may press the button to drive the pressure member, thereby opening the inlet port by the pressure member.

[0154] Finally, let us look at a battery storage container (40) according to another embodiment of the present invention, which includes a vent part (2300) in the configuration of the battery storage container (10, 20) according to one or another embodiment of the present invention described above.

[0155] FIG. 23 is a drawing for explaining the overall appearance of a battery storage container according to another embodiment of the present invention, FIG. 24 is a drawing for explaining a side view of a battery storage container according to another embodiment of the present invention, and FIG. 25 is a drawing for explaining a vent part of a battery storage container according to another embodiment of the present invention.

[0156] A battery storage container (40) according to another embodiment of the present invention including the cover portion (100), main body portion (200), and discharge portion (300b or 300a) described above may further include a vent portion (2300).

[0157] Here, the cover part (100), main body part (200), and discharge part (300b or 300a) are the same as described above, so the same drawing number is given and only the different parts are described.

[0158] The main body (200) may have an exhaust hole formed on one side to exhaust air to the outside, and may be connected to a vent part (2300) to be described later through the exhaust hole.

[0159] As described above, the vent part (2300) can be connected to the main body part (200) so that air can be discharged to the outside when the internal pressure of the main body part (200) increases.

[0160] Specifically, the vent section (2300) may include a body (2301) and a vent channel (2320).

[0161] The body (2301) is provided so that one side faces the main body (200) and may have a shape that is elongated in one direction. For example, the body (2301) may be provided in a rectangular shape that is elongated in one direction as illustrated in the drawing.

[0162] At this time, the vent channel (2320) may be provided to penetrate the above-described body (2301) in a diagonal direction based on the longitudinal direction of the above-described body (2301).

[0163] In other words, assuming that a virtual reference axis is formed along the longitudinal direction of the body (2301), the longitudinal axis of the vent channel (2320) may have a different direction from the above-described virtual reference axis.

[0164] Therefore, even if the length of the vent channel (2320) increases, there is an advantage in that the shape of the body (2301) can be formed so that the width is always constant in the direction perpendicular to the longitudinal direction of the body (2301) by only changing the angle inside the body (2301) based on the above-described virtual reference axis.

[0165] At this time, the vent channel (2320) can be connected to the exhaust hole formed in the main body (200) described above on one side of the body (2301) that is in contact with the main body (200).

[0166] Specifically, the vent channel (2320) has an inlet formed at one end in the longitudinal direction and an outlet formed at the other end, so that the internal air of the main body (200) can be discharged along the discharge hole of the main body (200) described above, and can be introduced into the inlet formed on the first surface of the body (2301) that faces the main body (200) and discharged through the outlet formed on the second surface of the body (2301) that is different from the first surface.

[0167] Here, assuming that the first surface of the body (2301) is a surface that faces the main body (200), the second surface of the body (2301) may be the opposite surface of the body (2301) in the width direction of the body (2301) based on the first surface described above.

[0168] In order to improve the air discharge speed, a protrusion is formed inside the vent channel (2320). At this time, the protrusion may be formed with a tip by narrowing the width in the direction of protrusion, and a plurality of protrusions may be arranged in the longitudinal direction of the vent channel (2320).

[0169] The distance between the tips of the protrusions described above can be set so that the vortex formed by the protrusions is not entrained, thereby further improving the speed at which the air is discharged.

[0170] These vent channels (2320) may be arranged to open according to preset conditions when at least one of the above-described inlets and outlets is closed, and the preset conditions may be the internal pressure of the main body (200) containing the battery.

[0171] For example, the vent channel (2320) is closed when a membrane is formed at the outlet or inlet, and when the internal pressure of the main body (200) increases above a preset pressure, air tears and penetrates the membrane of the outlet or inlet, allowing the air inside the main body (200) to be discharged to the outside of the main body (200) through the vent channel (2320).

[0172] The vent channel (2320) having the configuration described above may be configured to be opened according to the user's choice by further including a pressurizing member that opens the sealed inlet port according to an electrical signal.

[0173] Having described preferred embodiments of the invention, it will be apparent to those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or scope thereof, in addition to the embodiments described above.

[0174] Therefore, the above-described embodiments should be considered as illustrative rather than restrictive, and accordingly, the present invention is not limited to the above description but may be modified within the scope of the appended claims and their equivalents.

[0175] Even if the battery storage container (30, 40) according to another embodiment of the present invention, specifically described above, is mixed and includes both a sealing portion (1300) and a vent portion (2300), it will be said that both fall within the scope of the present invention.
