Description

Technical Field

[0001] The utility model relates to the technical field of pole piece sample storage, in particular to a pole piece sample storage bag. Background Art

[0002] During battery production, the quality of electrode production is crucial to battery performance. To ensure production quality, battery manufacturers typically sample produced electrode sheets and subject these samples to a series of tests, such as charge and discharge tests. The results of these tests are used to adjust various parameters in the production process to ensure electrode quality and consistency.

[0003] Currently, there are several issues with the storage and transportation of electrode samples. Some companies use stretch film for simple packaging, others use standard ziplock bags, and some even opt for no packaging at all. These methods all have significant drawbacks: during transfer and handling, electrode samples are prone to bending, wrinkling, and other deformations, seriously impacting electrode testing. Furthermore, when electrode samples are exposed to air, especially water or moisture, their performance can be significantly affected, impacting the accuracy of test results.

[0004] For example, the patent with announcement number CN219619799U discloses a pole piece sample storage bag, which is provided by setting a bag body with an opening at one end, and setting a seal at the bag opening, and at the same time setting a structural member for maintaining the shape of the bag body on at least one side of the bag body. This design can protect the pole piece samples to a certain extent and prevent the samples from deforming. However, the applicant found that this design still has some problems during actual use. Specifically, since the bag body is open at only one end, air resistance will be generated in the bag body when the pole piece sample is pushed into the bag body. Since the pole piece material is relatively soft, the pole piece will be affected by the air resistance during the pushing process and will curl and deform. On the one hand, it makes bagging difficult, and on the other hand, it will cause the sample pole piece to bend and be damaged, and its integrity cannot be maintained, which in turn affects the subsequent detection effect. Utility Model Content

[0005] In view of this, the utility model proposes a pole piece sample storage bag, which can easily load the pole piece samples while avoiding bending and deformation of the samples.

[0006] The technical solution of the present utility model is achieved as follows:

[0007] The utility model provides an electrode sample storage bag, comprising a bag body, wherein at least one side of the bag body is provided with a stabilizing member, both ends of the bag body are open, a bag opening is provided at the opening of the bag body, and a bag opening sealing member for closing the bag opening is provided at the bag opening.

[0008] In some embodiments, the area of ​​the stabilizing member is consistent with the side area of ​​the bag body.

[0009] As some other embodiments, the stabilizing member includes a supporting portion and a protecting portion, wherein the supporting portion is provided on the side of the bag body, and the protecting portion is formed by extending from the edge of the supporting portion toward an end of the bag body away from the bag opening.

[0016] On the basis of the above technical solution, preferably, the bag body is a flexible antistatic plastic bag.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) By setting the bag body with openings at both ends and setting the bag openings at the openings of the bag body, the design of openings at both ends not only helps to reduce air resistance, but also makes the operation of bagging and removing samples more convenient and quick. The operator can choose which end to operate from according to actual needs, which is more flexible.

[0026] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 As shown, combined Figure 2 The embodiment of the utility model discloses a pole piece sample storage bag, including a bag body 1 for accommodating pole piece samples. A stabilizing member 2 is provided on at least one side of the bag body 1. Both ends of the bag body 1 are open. A bag opening 3 is provided at the opening of the bag body 1. A bag opening sealing member 4 for closing the bag opening 3 is provided at the bag opening 3.

[0028] In this embodiment, the electrode sample enters the bag body 1 from the bag opening 3, and the bag opening seal 4 is used to seal the bag opening 3 to prevent water vapor and pollutants from entering the bag body 1 to contaminate the electrode, thereby protecting the performance of the sample and the accuracy of the test results.

[0029] The double-ended opening design not only helps reduce air resistance but also makes bagging and removing samples more convenient and quicker. Operators can choose which end to operate from based on their needs, providing greater flexibility. Furthermore, the double-ended opening design reduces air resistance during sample insertion, further preventing curling or bending of the electrode sample during bagging, and improving operational convenience.

[0030] The stabilizer 2 is used to maintain the shape of the bag 1, preventing deformation such as wrinkling, shrinking, and bending. The presence of the stabilizer 2 ensures that the bag 1 remains flat during storage and transportation, preventing deformation due to external forces. Therefore, the electrode sample stored in the bag 1 naturally maintains its shape. This effectively prevents bending or other deformation of the electrode sample during storage and transportation, ensuring the integrity of the sample.

[0031] In order to protect the bag body 1 from deformation, shrinkage and wrinkling, the stabilizer 2 is configured as a hard plate, and its corresponding plastic material includes PP, PE, PVC and other materials.

[0032] In some embodiments, the area of ​​the stabilizer 2 is consistent with the side area of ​​the bag body 1. Thus, the stabilizer 2 completely covers the side of the bag body 1. This design can more effectively prevent deformation of the outer wall of the bag body 1, such as wrinkling, shrinking, and bending, thereby enhancing the overall structural stability of the bag body 1.

[0033] In other embodiments, the stabilizer 2 includes a support portion 21 and a protective portion 22. The support portion 21 is disposed on the side of the bag body 1, and the protective portion 22 extends from the edge of the support portion 21 toward the end of the bag body 1 away from the bag opening 3. The support portion 21 is fixedly connected to the outer wall of the bag body 1, and the protective portion 22 is integrally formed with the support portion 21. The support portion 21 is used to maintain the bag body 1 in a flat and unfolded state, and the protective portion 22 is used to prevent the edge of the bag body 1 from curling.

[0034] When the stabilizer 2 is configured as a plate, the preferred thickness range of the stabilizer 2 is 0.5-3 mm to ensure the strength of the stabilizer 2 and save materials.

[0035] When the stabilizer 2 is disposed on the outside of the bag body 1, it can also block impact to a certain extent, thereby preventing external impact from directly acting on the electrode sample inside the bag body 1. In another embodiment, the stabilizer 2 is disposed on both sides of the bag body 1 to fully protect the electrode sample inside the bag body 1 from external impact.

[0036] After the electrode is placed in the bag 1, the bag 1 must first be squeezed to expel the air inside the bag 1, and then the bag opening 3 and the bag 1 must be sealed. However, this does not guarantee that the air inside the bag 1 is fully exhausted, and may cause the bag 1 to swell or bulge, which is not conducive to maintaining the shape and stability of the bag 1, especially during storage and transportation. At the same time, when there is too much air in the bag 1, there is a risk of oxidation of the electrode due to contact with air.

[0037] Therefore, in this embodiment, a one-way exhaust valve 5 is provided on the outside of the bag body 1. The one-way exhaust valve 5 allows the gas inside the bag to escape, preventing gas accumulation inside the bag, thereby preventing the bag body 1 from expanding or bulging. At the same time, the one-way exhaust valve 5 can prevent external air from entering the bag, helping to prevent external moisture from entering, thereby protecting the electrode sample from the influence of a humid environment and preventing the sample from deteriorating due to moisture.

[0038] In some embodiments, an identification area 6 is provided on the outside of the bag 1 for storing an identification card containing information about the electrode sample. A technician can identify and select the target bag 1 based on the information on the identification card.

[0039] As some preferred embodiments, the bag body 1 is a flexible antistatic plastic bag, which prevents the bag body 1 from sticking, making it more convenient to load or remove the electrode, reducing operational difficulty and time waste.

[0040] In some embodiments, the bag opening seal 4 includes a first adhesive strip and a second adhesive strip that are sealed to each other. The first and second adhesive strips are respectively disposed on the inner side of the bag opening. Both the first and second adhesive strips are coated with adhesive, and the first and second adhesive strips are adhered to each other to seal the bag opening 3. In other embodiments, release paper may be provided on the first and second adhesive strips, and the first and second adhesive strips can be bonded to each other by removing the release paper.

[0041] In some embodiments, the bag opening seal 4 includes an elastic slot and an elastic clip that are sealed and engaged with each other. The elastic clip and the elastic slot are respectively fixedly disposed on the inner side of the bag opening. The elastic slot is slightly smaller than the elastic clip. Both the elastic slot and the elastic clip are made of elastic plastic. The elastic clip can be snapped into the elastic slot to seal the bag opening 3.

[0042] The above two sealing methods can ensure that the bag mouth can be effectively sealed to prevent external air from entering the bag. At the same time, under the action of the one-way exhaust valve, the air in the bag can be completely discharged to ensure that there is no air or as little air as possible inside the bag, thereby ensuring a reliable storage environment for the electrode samples and improving the test results.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
