[0038] Please refer to Figures 1 to 7 In some embodiments, the battery 100 includes: a shell 200, a pole 300, a cover plate (not shown in the figure), a battery cell 400 and an insulating member 500. The shell 200 has a storage cavity 210, and the shell 200 includes a first surface 220, a second surface 230, a third surface 240, a fourth surface 250 and a fifth surface 260. Among them, the first surface 220 and the second surface 230 are arranged opposite to each other, the third surface 240 and the fourth surface 250 are arranged opposite to each other, and the first surface 220, the second surface 230, the third surface 240 and the fourth surface 250 are connected to the fifth surface 260 together to form a storage cavity 210. The pole 300 is connected to the first surface 220, and one end of the pole 300 protrudes relative to the shell 200. That is, the pole 300 passes through the shell 200 so that it can be connected to the outside world. Among them, when the shell 200 and the negative pole ear 430 are connected, in order to avoid the shell 200 and the pole 300 from short-circuiting, the pole 300 and the shell 200 can be insulated. The cover plate is connected to the shell 200. The cover plate can be connected to the shell 200 by welding, and the cover plate and the fifth surface 260 are arranged relative to each other, so that the cover plate closes the opening of the storage cavity 210. The battery cell 400 is arranged in the storage cavity 210. The battery cell 400 refers to the core component for providing power to equipment such as power supply or power tools. It is the main body 410 part of the battery 100 and plays the role of storing and releasing electrical energy. The battery cell 400 is composed of a positive electrode, a negative electrode, an electrolyte and a diaphragm, etc., and can store and release electrical energy in a chemical reaction. The working principle of the battery cell 400 is to generate electrical energy by using the chemical reaction between the positive electrode and the negative electrode, thereby realizing the storage and release of charge. When the battery 100 is used, the positive electrode releases electrons, and the negative electrode absorbs electrons. The electrons generate current output through the load, so that the electrical appliance can work. During charging, the power source outputs current to the battery 100, prompting the positive and negative electrodes to react chemically in reverse, and storing the charge again inside the battery cell 400. The battery cell 400 includes a main body 410, a positive electrode ear 420, and a negative electrode ear 430. The two ends of the positive electrode ear 420 are respectively connected to the main body 410 and the pole 300, and the two ends of the negative electrode ear 430 are respectively connected to the main body 410 and the shell 200. In this way, the positive electrode of the battery cell 400 is connected to the outside world through the pole 300, and the negative electrode of the battery cell 400 is connected to the outside world through the shell 200. The material of the shell 200 can be aluminum alloy, stainless steel, etc.

[0039] Please refer to Figures 1 to 4, the insulating member 500 is disposed between the main body 410 and the first surface 220. The insulating member 500 is provided with a negative electrode hole 530, a positive electrode hole 520 and a first through hole 510, the positive electrode ear 420 is disposed in the positive electrode hole 520, and the negative electrode ear 430 is disposed in the negative electrode hole 530. Specifically, the insulating member 500 is located between the main body 410 and the first surface 220, and the insulating member 500 can play an insulating role, wherein the negative electrode hole 530, the positive electrode hole 520 and the first through hole 510 are provided on the insulating member 500, the negative electrode hole 530 can be used for the negative electrode ear 430 to pass through, and the positive electrode hole 520 can be used for the positive electrode ear 420 to pass through, and the specific reference can be made to Figure 6 and Figure 7 Specifically, since the first through hole 510 is provided on the insulating member 500, the weight of the insulating member 500 can be reduced by providing the first through hole 510 on the insulating member 500, thereby further effectively reducing the weight of the battery 100. That is, the battery 100 can have the characteristic of being lighter in weight.

[0040] Among them, by providing the first through hole 510 on the insulating member 500, the weight of the insulating member 500 can be reduced. The shape of the first through hole 510 is not specifically limited, and the shape of the first through hole 510 can be circular, square, triangular or polygonal. It can be imagined that the larger the area of ​​the first through hole 510, the lighter the weight of the insulating member 500. Punching the first through hole 510 on the insulating member 500 can be done by mechanical punching or laser punching.

[0041] Further, in some embodiments, the material of the insulating member 500 is one of polyetheretherketone, polyimide, polyetheretherketone composite material, thermoplastic elastomer and polyphenylene sulfide. Polyetheretherketone (PEEK) is a high-performance thermoplastic plastic material with a certain elasticity, which can be deformed within a certain range and return to its original state after the external force disappears. Polyimide (PI) is a special engineering material with excellent high temperature resistance. The polyetheretherketone composite material is based on polyetheretherketone resin and is reinforced by adding other materials (such as fibers). Since the matrix material PEEK itself has a certain elasticity, the composite material will also show certain elastic properties. Thermoplastic elastomer (TPE) has both the high elasticity of traditional cross-linked vulcanized rubber and the characteristics of convenient processing of ordinary plastics. Its elastic properties are significant, and it can be freely deformed within a certain range and return to its original state. Polyphenylene sulfide (PPS) also has a certain elasticity. Specifically, when the insulating member 500 is made of one of the above materials, the insulating member 500 has good elasticity and insulation, so the insulating member 500 can insulate the battery cell 400 and the housing 200 on the one hand, and can also play a buffering role on the other hand. In addition, the above materials are all resistant to high temperatures. Since the battery cell 400 generates heat during charging and discharging, the high temperature resistance can also prolong the service life of the insulating member 500.

[0042] Furthermore, the Shore hardness of the material of the insulating member 500 is ≤90 degrees. If the Shore hardness of the insulating member 500 is greater than 90 degrees, the insulating member 500 may pierce the battery cell 400 due to its excessive hardness when dropped, causing damage to the battery cell 400. The Shore hardness of the insulating member 500 may be 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees or 90 degrees.

[0043] Further, in some embodiments, along the length direction of the battery 100, the projection of the insulating member 500 falls within the projection range of the main body 410. Specifically, one end of the insulating member 500 abuts against the main body 410, and the other end abuts against the first surface 220. Compared with the way that the insulating member 500 is sleeved on the main body 410, the way that the insulating member 500 abuts against the main body 410 is not easy to damage the battery cell 400.

[0044] Furthermore, in some embodiments, the insulating member 500 is provided with a placement cavity. Specifically, the provision of the placement cavity makes the insulating member 500 a hollow structure. After the insulating member 500 forms a hollow structure, the insulating member 500 can further reduce the weight, thereby making the battery 100 lighter.

[0045] Further, in some embodiments, the insulating member 500 is provided with a placement cavity, and the cavity wall of the placement cavity includes a first wall, a second wall and a third wall arranged oppositely, and a fourth wall and a fifth wall arranged oppositely. The second wall, the third wall, the fourth wall and the fifth wall are connected to the first wall together to form a placement cavity. Among them, the positive electrode hole 520, the negative electrode hole 530 and the first through hole 510 can be located on any one of the wall surfaces. The following is one of the ways. The first wall is provided with a positive electrode hole 520 and a negative electrode hole 530, and the first through hole 510 is located on one of the second wall, the third wall, the fourth wall and the fifth wall. That is, the positive electrode hole 520 and the negative electrode hole 530 are arranged on the first wall, the first through hole 510 can be located on the second wall, the first through hole 510 can be located on the third wall, the first through hole 510 can be located on the fourth wall, and the first through hole 510 can be located on the fifth wall. The weight of the insulating member 500 can be reduced by the arrangement of the first through hole 510.

[0046] For further information, please refer to Figure 1 In some embodiments, the insulating member 500 is provided with a placement cavity, and the cavity wall of the placement cavity includes a first wall, a second wall and a third wall arranged oppositely, and a fourth wall and a fifth wall arranged oppositely. The second wall, the third wall, the fourth wall and the fifth wall are connected to the first wall together to form a placement cavity. Among them, the positive electrode hole 520, the negative electrode hole 530 and the first through hole 510 can be located on any wall surface. The following is one of the ways. The first wall is provided with a positive electrode hole 520, a negative electrode hole 530 and a first through hole 510. That is, the first through hole 510, the positive electrode hole 520 and the negative electrode hole 530 are arranged on the first wall. The way of arranging the first through hole 510, the positive electrode hole 520 and the negative electrode hole 530 on the same wall surface can facilitate the manufacturing and processing of the staff. When punching holes on the insulating member 500, the processing can be completed by punching holes on one wall surface of the insulating member 500, without moving the insulating member 500 to allow other wall surfaces to be processed.

[0047] Further, in some embodiments, the first wall is provided with a positive electrode hole 520, a negative electrode hole 530 and a first through hole 510, and the second wall, the third wall, the fourth wall and the fifth wall are provided with a first through hole 510. In this way, by providing a plurality of first through holes 510, the insulating member 500 can be made lightweight.

[0048] Further, in some embodiments, the first surface 220 is provided with a liquid injection hole connected to the storage cavity 210, and the first wall is further provided with a liquid passing hole 560, the liquid injection hole and the liquid passing hole 560 are arranged opposite to each other, and a plurality of first through holes 510 are provided, and the plurality of first through holes 510 surround the periphery of the liquid passing hole 560. Specifically, the liquid injection hole is used to inject electrolyte into the interior of the battery 100, that is, into the storage cavity 210. After the electrolyte passes through the liquid injection hole, the electrolyte will pass through the liquid passing hole 560 and thus contact the battery cell 400. Among them, after the plurality of first through holes 510 surround the periphery of the liquid passing hole 560, after the electrolyte enters the storage cavity 210 from the liquid injection hole, the electrolyte will pass through the plurality of first through holes 510 and the liquid passing hole 560, which can accelerate the speed of the electrolyte infiltrating the battery cell 400. That is, the plurality of first through holes 510 and the liquid passing hole 560 cooperate with each other to enable the electrolyte to quickly enter the pole piece of the battery cell 400.

[0049] Furthermore, generally speaking, the purpose of providing the positive electrode hole 520 and the negative electrode hole 530 on the insulating member 500 is to facilitate the passage of the positive electrode ear 420 and the negative electrode ear 430. That is, when installing the battery 100, the position of the positive electrode hole 520 needs to be aligned with the position of the positive electrode ear 420, so that the positive electrode ear 420 can pass through the positive electrode hole 520. In some embodiments, the first through hole 510 is connected to the positive electrode hole 520 to form a second through hole 540. That is, when processing the insulating member 500, a second through hole 540 can be directly punched out, and the area of ​​the second through hole 540 is equal to the sum of the area of ​​the first through hole 510 and the area of ​​the positive electrode hole 520. Please refer to Figure 3 , Figure 3 The middle positive electrode hole 520 is indicated by a dotted line. The width of the insulating member 500 is L1, the length of the second through hole 540 is L2, the width of the second through hole 540 is L3, 1mm≤L2≤10mm, 1mm≤L1-L3≤10mm. Specifically, the shape of the positive electrode ear 420 can be a rectangle, and the shape of the second through hole 540 can also be a rectangle, so that the second through hole 540 is adapted to the positive electrode ear 420. Among them, when the length and width of the second through hole 540 respectively meet 1mm≤L2≤10mm, 1mm≤L1-L3≤10mm, it can be imagined that the length of the second through hole 540 is much greater than the width of the positive electrode ear 420, and the width of the second through hole 540 is much greater than the thickness of the positive electrode ear 420, which can provide greater fault tolerance when the positive electrode ear 420 passes through the second through hole 540, thereby accelerating the installation efficiency of the battery 100. Wherein, L2 may be 1 mm, 2 mm, 4 mm, 5 mm, 8 mm or 10 mm. L1-L3 may be 1 mm, 2 mm, 4 mm, 5 mm, 8 mm or 10 mm.

[0050] It is described above that the second through hole 540 can be formed by connecting the first through hole 510 and the negative electrode hole 530, so as to facilitate the positive electrode ear 420 to pass through. Similarly, the first through hole 510 and the negative electrode hole 530 can also be connected. Specifically, in some embodiments, the first through hole 510 is connected with the negative electrode hole 530 to form a third through hole 550, that is, when processing the insulating member 500, a third through hole 550 can be directly punched out, and the area of ​​the third through hole 550 is equal to the sum of the area of ​​the first through hole 510 and the area of ​​the negative electrode hole 530. Please refer to Figure 3 , Figure 3 The middle negative electrode hole 530 is indicated by a dotted line. The width of the insulating member 500 is L1, the length of the third through hole 550 is L4, the width of the third through hole 550 is L5, 1mm≤L4≤10mm, 1mm≤L1-L5≤10mm. Specifically, the shape of the negative electrode ear 430 can be rectangular, and the shape of the third through hole 550 can also be rectangular, so that the third through hole 550 is adapted to the negative electrode ear 430. Among them, when the length and width of the third through hole 550 respectively meet 1mm≤L4≤10mm, 1mm≤L1-L5≤10mm, it can be imagined that the length of the third through hole 550 is much greater than the width of the negative electrode ear 430, and the width of the third through hole 550 is much greater than the thickness of the negative electrode ear 430, which can provide greater fault tolerance when the negative electrode ear 430 passes through the third through hole 550, thereby accelerating the installation efficiency of the battery 100. Among them, L4 can be 1mm, 2mm, 4mm, 5mm, 8mm or 10mm. L1-L5 can be 1mm, 2mm, 4mm, 5mm, 8mm or 10mm.

[0051] The manufacturing method of the battery 100 is described below. In some embodiments, the manufacturing method of the battery 100 includes the following steps:

[0052] Punching a negative electrode hole 530 , a positive electrode hole 520 and a first through hole 510 on the insulating member 500 ;

[0053] The insulating member 500 and the battery cell 400 are placed in the housing 200 .

[0054] Specifically, after the first through hole 510 is provided on the insulating member 500, the weight of the insulating member 500 can be reduced, thereby further reducing the weight of the battery 100. In this way, the battery 100 can have the characteristic of being light in weight.

[0055] Among them, the specific steps of the manufacturing method of the battery 100 may be to process the shell 200, the battery cell 400 and the insulating part 500, punch out the negative electrode hole 530, the positive electrode hole 520 and the first through hole 510 on the insulating part 500, place the insulating part 500 and the battery cell 400 into the shell 200, weld the positive electrode ear 420 and the pole 300, weld the negative electrode ear 430 and the shell 200, weld the cover plate to the shell 200 to close the storage cavity 210, and inject the electrolyte into the storage cavity 210 from the injection hole, thereby completing the manufacture of the battery 100.

[0056] Further, in some embodiments, punching the negative electrode hole 530, the positive electrode hole 520 and the first through hole 510 on the insulating member 500 further includes the following steps: connecting the positive electrode hole 520 with the first through hole 510 to form the second through hole 540, and connecting the negative electrode hole 530 with the first through hole 510 to form the third through hole 550. Specifically, after the second through hole 540 is formed by connecting the first through hole 510 and the positive electrode hole 520, the size of the positive electrode hole 520 can be indirectly increased, so that the positive electrode ear 420 can pass through the second through hole 540 conveniently. Similarly, after the third through hole 550 is formed by connecting the first through hole 510 and the negative electrode hole 530, the size of the negative electrode hole 530 can be indirectly increased, so that the negative electrode ear 430 can pass through the third through hole 550 conveniently. In this way, since the sizes of the second through hole 540 and the third through hole 550 are large, it is convenient for the positive electrode ear 420 and the negative electrode ear 430 to pass through respectively, which can improve the manufacturing efficiency.

[0057] In some embodiments, an electronic device includes the battery in the above embodiments. Specifically, since the first through hole 510 is provided on the insulating member 500, the weight of the insulating member 500 can be reduced by providing the first through hole 510 on the insulating member 500, thereby further effectively reducing the weight of the battery 100. That is, the battery 100 can have the characteristic of being light in weight. Further, the electronic device having the battery 100 is light in weight.

[0058] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
