[0032] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention, and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of it.

[0033] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed or detachable connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0034] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0035] like Figure 1-Figure 5 As shown, the battery storage device of this embodiment is used to store materials. Figure 2 The ab direction is the first direction, the cd direction is the second direction, and the ef direction is the third direction.

[0036] The battery storage device includes a material frame 1 and multiple partitions 2. The multiple partitions 2 are arranged in parallel and sequentially along a first direction within the material frame 1. A material storage space 11 is defined between two adjacent partitions 2. The material storage space 11 is used to accommodate materials. When multiple partitions 2 are provided within a material frame 1, multiple material storage spaces 11 are formed, sequentially along the first direction, allowing for neat storage of multiple materials.

[0037] The first side surface 31 of the material has a first protrusion 311 and a second protrusion 312, and the second side surface 21 of the partition 2 has an anti-fouling limiter. When the material is located in the storage space 11, the first side surface 31 faces the second side surface 21. That is, the first protrusion 311 and the second protrusion 312 are arranged opposite the anti-fouling limiter. When the first end 32 of the material along the second direction corresponds to the second end 22 of the partition 2 along the second direction, the anti-fouling limiter is located between the first protrusion 311 and the second protrusion 312. The anti-fouling limiter does not interfere with the first protrusion 311 and the second protrusion 312, and the material can be inserted into the storage space 11. When the first end 32 of the material along the second direction corresponds to the third end 23 of the partition 2 along the second direction, the fool-proof limit portion interferes with the first protrusion 311 and / or the second protrusion 312, that is, the fool-proof limit portion interferes with the first protrusion 311, or the fool-proof limit portion interferes with the second protrusion 312, or the fool-proof limit portion interferes with both the first protrusion 311 and the second protrusion 312, and the material cannot be inserted into the storage space 11. The second direction is perpendicular to the first direction.

[0038] The battery storage device can prevent materials from being placed upside down in the second direction, which would prevent the materials from being smoothly inserted into the storage space 11 of the material frame 1. The correct storage direction of materials in the battery storage device can prevent the materials from being assembled upside down in the second direction during subsequent assembly, thereby ensuring the yield and efficiency of the battery manufacturing process.

[0039] When the material is lower plastic and the second direction is the length direction of the lower plastic, the battery material storage device can help prevent the lower plastic from being installed upside down along the length direction, ensuring that the lower plastic is assembled correctly, thereby improving the process yield and efficiency of the battery.

[0040] Optionally, the first protrusion 311 has a first inclined surface 3111, and the foolproof limiter has a second inclined surface 2111. When the first end 32 corresponds to the second end 22, the second inclined surface 2111 is arranged relatively parallel to the first inclined surface 3111. The first inclined surface 3111 is parallel to the third direction. The material is inserted into the storage space 11 along the third direction, and the third direction is perpendicular to both the first and second directions. The second inclined surface 2111 not only limits the position of the first inclined surface 3111 when the material is stored in the second direction, but also interferes with the second protrusion 312 when the material is loaded upside down.

[0041] Optionally, the included angle between the first inclined surface 3111 and the first side surface 31 is an obtuse angle, and the included angle between the second inclined surface 2111 and the second side surface 21 is an obtuse angle.

[0042] Optionally, the first inclined surface 3111 is provided along the third direction through the first side surface 31. Optionally, the second inclined surface 2111 is provided along the third direction through the second side surface 21, that is, the limiting effect of the second inclined surface 2111 on the first inclined surface 3111 is consistent everywhere along the third direction, which helps to ensure that the lower plastic is not skewed.

[0043] To prevent the first side 31 of the material from being inserted into the storage space 11 away from the second side 21 of the partition 2, that is, toward the third side 24 of the partition 2, the height of the anti-foolproof limiter along the first direction is a, the larger of the heights of the first protrusion 311 and the second protrusion 312 along the first direction is b, and the width of the storage space 11 at its widest point along the first direction is c, where a+b>c. That is, when the first side 31 of the material is inserted into the storage space 11 away from the second side 21 of the partition 2, the thickness of the anti-foolproof limiter and the first protrusion 311 or the second protrusion 312 need to overlap, and the storage space 11 will be insufficiently wide, preventing the material from being inserted into the storage space 11. This can provide limited protection against the material being placed upside down.

[0044] Optionally, the first side surface 31 of the material further has a liquid injection hole support protrusion 313. When the first end 32 corresponds to the second end 22, the anti-foolproof limit portion does not interfere with the liquid injection hole support protrusion 313. When the first end 32 corresponds to the third end 23, the anti-foolproof limit portion interferes with the liquid injection hole support protrusion 313, which can further prevent the material from being placed upside down at both ends along the second direction.

[0045] Optionally, the foolproof limiter includes a third protrusion 211 and a fourth protrusion 212, wherein the third protrusion 211 is used to limit the first protrusion 311, and the fourth protrusion 212 is used to limit the second protrusion 312. Specifically, the third protrusion 211 and the fourth protrusion 212 are both located between the first protrusion 311 and the second protrusion 312, with the third protrusion 211 positioned closer to the first protrusion 311 and the fourth protrusion 212 positioned closer to the second protrusion 312. When the distance between the third protrusion 211 and the first protrusion 311 is small, and the distance between the fourth protrusion 212 and the second protrusion 312 is small, that is, when the distance between the third protrusion 211 and the fourth protrusion 212 is large, the material can be prevented from moving in the second direction. The injection hole support protrusion 313 is positioned closer to the first protrusion 311. When the material is placed upside down, the fourth protrusion 212 will interfere with the injection hole support protrusion 313.

[0046] Optionally, both ends of the third side surface 24 of the partition plate 2 along the second direction are provided with limiting protrusions 241, and the material in the storage space 11 enclosed by the third side surface 24 is located between the two limiting protrusions 241. In other words, the two limiting protrusions 241 arranged relatively spaced apart along the second direction can further limit the movement of the material in the second direction, ensuring that the third protrusion 211 and the fourth protrusion 212 are located between the first protrusion 311 and the second protrusion 312.

[0047] To reduce the weight of the battery storage device, the partition 2 may optionally have a weight-reducing hollow 201. Alternatively, the bottom plate of the material frame 1 may also have a weight-reducing hollow 201. Alternatively, the bottom plate of the material frame 1 may be composed of two long plates spaced apart, with the gap between the two long plates serving as the weight-reducing hollow 201. Alternatively, the end plates of the material frame 1 at both ends along the first direction may have weight-reducing hollows 201. Of course, in other embodiments, the two side plates of the material frame 1, positioned opposite each other along the second direction, may also have weight-reducing hollows 201.

[0048] In order to prevent the material frames 1 from being placed upside down during the stacking process, optionally, one end of the material frame 1 along the first direction is a first end plate 12, and the two ends of the first end plate 12 along the third direction are respectively provided with matching fifth protrusions 121 and first grooves 122. When multiple material frames 1 are stacked in sequence along the third direction, when the first end plates 12 of two adjacent material frames 1 are at one end, the fifth protrusions 121 are inserted into the first grooves 122. The second end plates 13 of the material frames 1 are arranged opposite to the first end plates 12, and the second end plates 13 are not provided with a second groove matching the fifth protrusion 121, or a sixth protrusion matching the first groove 122. Therefore, if the material frames 1 are placed upside down, that is, when the upper material frame 1 and the first end plate 12 are at the same end as the second end plate 13 of the lower material frame 1, the upper material frame 1 cannot be placed stably, and can be moved relative to the lower material frame 1 along the second direction, so that the problem can be immediately discovered and corrected.

[0049] Optionally, the fifth protrusion 121 is provided on the lower edge of the first end plate 12 and protrudes downward, and the first groove 122 is provided on the upper edge of the first end plate 12 and extends downward. Of course, in other embodiments, the fifth protrusion 121 can also be provided on the upper edge, and the first groove 122 can be provided on the lower edge.

[0050] Optionally, in other embodiments, a concave-convex structure with a different position from that of the first end plate 12 can be set on the second end plate 13. On the one hand, it can further improve the limiting effect between two adjacent material frames 1 when the material frame 1 is placed correctly, and the placement is more secure. On the other hand, it can also ensure that there is an interference prevention effect when the material frame 1 is placed upside down.

[0051] like Figure 6-Figure 7 As shown in the figure, among the three material frames 1, the first material frame 1 on the top is placed in the wrong direction, while the two material frames 1 on the bottom are placed in the same direction. Figure 6 As shown, the fifth protrusion 121 of the second material frame 1 is inserted into the first groove 122 of the third material frame 1, and the two are placed stably. Figure 6 At the end shown in the figure, the first material frame 1 and the second material frame 1 do not interfere with each other. Figure 7 At one end shown in the figure, the first material frame 1 and the second material frame 1 have an interference area 500, that is, this end of the first material frame 1 is higher, causing the first material frame 1 to be uneven and able to move freely relative to the second material frame 1, which is convenient for staff to discover and correct in time.

[0052] Optionally, the material frame 1 includes a positive electrode material frame and a negative electrode material frame, the separator 2 includes a positive electrode separator and a negative electrode separator, and a plurality of positive electrode separators are arranged in the positive electrode material frame to form a positive electrode storage device 100, which is used to store the positive electrode lower plastic 300. Figures 1-4 As shown. A plurality of negative electrode separators are arranged in the negative electrode material frame to form a negative electrode storage device 200, which is used to store the negative electrode lower plastic 400. Figure 5 shown.

[0053] When the material is lower plastic, the battery material storage device includes a positive electrode storage device 100 and a negative electrode storage device 200, respectively storing positive electrode lower plastic 300 and negative electrode lower plastic 400. Of course, the material can also be other battery components such as cover plates. Designing a battery material storage device in this manner can prevent the material from being misplaced, helping to ensure correct assembly during the battery assembly process, thereby improving the yield and efficiency of the battery manufacturing process.

[0054] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
