Description

Technical Field

[0001] This utility model belongs to the field of electrode testing technology, and in particular relates to an electrode liquid absorption monitoring device. Background Technology

[0002] Electrolyte uptake rate refers to the rate at which electrolyte is drawn into the battery. It can be used to describe the diffusion process inside the battery and the stability of battery performance. Typically, a porous network exists between the negative and positive electrodes of a battery. The electrolyte moves within these pores and enters the electrode interior, thus providing the raw materials required for the electrode reactions.

[0003] Battery performance is closely related to electrolyte uptake rate. Different batteries use electrolytes with different uptake rates, and the uptake rate affects the electrolyte diffusion rate, thus impacting overall battery performance. Therefore, determining the electrolyte uptake rate is crucial for battery safety, stability, and performance, providing valuable reference information for battery design and optimization.

[0004] For example, the patent "CN 221506615U" discloses an electrode wettability testing device. In this patent, there is a container tank containing electrolyte, and a fixing member is provided on the container tank. The electrode is adhered to the fixing member. In this patent, the electrode is only fixed by adhesive strips. The electrode has a high probability of falling into the container tank, which makes it impossible to accurately observe the electrode's liquid absorption rate. At the same time, the electrode cannot be raised or lowered, so the area of ​​the electrode immersed in the liquid cannot be controlled. Utility Model Content

This device aims to solve the technical problems of existing testing devices being unable to properly fix the electrode and control the electrode immersion area.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms “comprising” and “having”, and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion.

[0036] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0037] The following is in conjunction with the appendix Figures 1-6 The present invention will be described in further detail, but this is not intended to limit the scope of the present invention.

[0038] Example 1

[0039] The electrode 4 liquid absorption monitoring device disclosed in this embodiment includes a detection component 1, a liquid storage component 2 and a positioning component 3. The detection component 1 is used to record the process of the electrode 4 absorbing electrolyte.

[0040] The liquid storage assembly 2 is provided with a liquid storage tank 21, which is used to store electrolyte;

[0041] The positioning component 3 is used to fix the electrode 4 and can raise or lower the electrode 4 so that the electrode 4 is partially immersed in the electrode liquid in the storage tank 21.

[0042] Specifically, the positioning component 3 is used to clamp and fix the electrode 4 to prevent it from falling off. After fixing the electrode 4, it also moves the electrode 4 up and down, coordinating with the liquid storage component 2 to control the area of ​​the electrode 4 immersed in the electrolyte, thus enabling testing of different variables. Since the electrolyte evaporates rapidly when the electrode 4 absorbs the electrolyte, making it difficult for the human eye to observe, a detection component 1 is set up to record the process of the electrode 4 absorbing the electrolyte. Finally, the recorded photos or videos are used to determine the electrolyte absorption performance of the electrode 4.

[0043] In this embodiment, the positioning component 3 includes a moving part 31 and a fixed part 32, which are disposed opposite to each other, and the moving part 31 moves toward the fixed part 32 to clamp the electrode 4.

[0044] Specifically, the moving part 31 and the fixed part 32 are arranged opposite to each other and there is a clamping space between the moving part 31 and the fixed part 32. During operation, the electrode 4 is first placed in the clamping space between the moving part 31 and the fixed part 32. Then, the moving part 31 is activated and moves towards the fixed part 32. The fixed part 32 remains stationary. Finally, the moving part 31 and the fixed part 32 come into contact to clamp the electrode 4. When the moving part 31 moves towards the fixed part 32, the moving part 31 comes into contact with the fixed part 32 or the electrode 4 until the moving part 31 can no longer move. This method can fix the electrode 4 more stably.

[0045] In this embodiment, the moving part 31 has a driving member 313, and the output end of the driving member 313 is provided with an abutment plate 314. The driving member 313 drives the abutment plate 314 to move toward the fixed part 32.

[0046] Specifically, in this embodiment, the driving member 313 on the moving part 31 drives the abutment plate 314 to move towards the fixing part 32. Automatic movement and clamping are achieved by the driving member 313, without the need for manual fixing of the electrode 4. When the abutment plate 314 and the designated functional part clamp the electrode 4, the driving member 313 always pushes the abutment plate 314 towards the fixing part 32, so that the electrode 4 is fixed in the abutment plate 314.

[0047] In this embodiment, the driving component 313 can be a combination of a driving cylinder, a motor and a lead screw, or other structures that can achieve the effect of this application. The driving component 313 is not limited here.

[0048] In this embodiment, the moving part 31 further includes a support plate 311 and a carrier plate 312. The carrier plate 312 is disposed on one side of the support plate 311 and is slidably connected to the support plate 311. The carrier plate 312 is perpendicular to the support plate 311, and the driving member 313 is fixedly disposed on the carrier plate 312.

[0049] The support plate 311 supports the carrier plate 312, allowing the carrier plate 312 to move up and down along the support plate 311. The carrier plate 312 is perpendicular to the support plate 311, ensuring that the moving direction of the abutment plate 314 is always consistent and will not deviate. Specifically, the carrier plate 312 is perpendicular to the support plate 311, and the driving member 313 is also perpendicular to the support plate 311. When the driving member 313 drives the abutment plate 314 to move, the moving trajectory of the abutment plate 314 is always a straight line, ensuring that the abutment plate 314 is always in contact with the fixing part 32, thereby improving the stability of the electrode 4 clamping.

[0050] In this embodiment, a sliding groove 315 is provided on the support plate 311. The sliding groove 315 is provided along the height direction of the support plate 311 and passes through the support plate 311. A mounting hole is provided on the bearing plate 312. The mounting hole is opposite to the sliding groove 315. A fixing member 316 is provided in the sliding groove 315. The fixing member 316 passes through the sliding groove 315 and connects with the mounting hole.

[0051] Specifically, firstly, the bearing plate 312 is connected to the support plate 311 via a fastener 316 to prevent the bearing plate 312 from falling off the support plate 311. Secondly, a sliding groove 315 is provided on the support plate 311, and the fastener 316 is located in the sliding groove 315. When the bearing plate 312 moves, the fastener 316 limits the bearing plate 312 to prevent it from deviating. At the same time, due to the setting of the sliding groove 315, when the bearing plate 312 moves, it drives the fastener 316 to move within the sliding groove 315. Therefore, when the bearing plate 312 moves, the sliding groove 315 guides the bearing plate 312.

[0052] In this embodiment, the fixing part 32 includes a slide rod 321, a slider 322, and a fixing plate 323. The slide rod 321 is disposed on both sides of the liquid storage component 2. The slider 322 is slidably connected to the slide rod 321 on both sides of the liquid storage component 2. The two ends of the fixing plate 323 are respectively connected to the slider 322. The slider 322 drives the fixing plate 323 to move along the extension direction of the slide rod 321. The slider 322 is provided with fixing screws. The slider 322 can be moved and fixed by turning the fixing screws.

[0053] Specifically, the fixing part 32 and the moving part 31 are configured to cooperate. The slide rod 321 is used to support the slider 322 and the fixing plate 323. The slide rod 321 slides along the extension direction of the slide rod 321. The fixing plate 323 is placed between the two sliders 322. When the sliders 322 slide, they drive the fixing plate 323 to move up and down. The fixing plate 323 cooperates with the abutment plate 314. The fixing plate 323 and the abutment plate 314 together clamp the electrode 4. The fixing plate 323 and the abutment plate 314 move synchronously. After clamping the electrode 4, the fixing plate 323 and the abutment plate 314 move up and down synchronously to change the area of ​​the electrode 4 immersed in the electrolyte.

[0054] In this embodiment, the detection device includes a first camera 11 and a second camera 12, which are arranged side by side.

[0055] Specifically, the two cameras are set up side by side, with each camera taking pictures of a portion of the electrode 4. Therefore, the first camera 11 and the second camera 12 can be placed closer to the electrode 4, resulting in clearer pictures.

[0056] Example 2

[0057] like Figure 2 As shown, unlike the previous embodiment, in this embodiment, a lifting member 317 is provided between the support plate 312 and the ground. The bottom of the lifting member 317 is in contact with the ground, and the output end of the lifting member 317 is connected to the support plate 312.

[0058] Specifically, the lifting component 317 can be a lifting cylinder, a drive motor and screw working together, or any other device that can achieve the effect of this embodiment.

[0059] The lifting component 317 drives the support plate 312 and the driving component 313 on the support plate 312 to move up and down, so that the electrode 4 moves up and down.

[0060] Example 3

[0061] like Figure 3 As shown, unlike the previous embodiment, in this embodiment, a base plate 318 is provided under the support plate 312, and a scissor arm 319 is provided between the base plate 318 and the support plate 312. The scissor arm 319 includes a first lever arm 3191 and a second lever arm 3192, which are rotatably connected. One end of the first lever arm 3191 is fixedly connected to the base plate 318, and the other end of the first lever arm 3191 is slidably connected to the support plate 312. One end of the second lever arm 3192 is movably connected to the base plate 318, and the other end of the second lever arm 3192 is fixedly connected to the support plate 312.

[0062] Specifically, the scissor arm 319 generates driving force by rotating relative to the first lever arm 3191 and the second lever arm 3192. The support plate 312 rises and falls by the driving force. In this embodiment, the scissor arm 319 and the support plate 312 have at least two contact points. With the support plate 311 fixing the support plate 312, the support plate 312 rises and falls more smoothly when driven to rise and fall.

[0063] Furthermore, multiple scissor arms 319 can be installed between the support plate 312 and the base plate 318 to make the movement of the support plate 312 more stable.

[0064] Example 4

[0065] like Figure 4 As shown, unlike Embodiment 1, in this embodiment, the fixing plate 323 is provided with a clamping part 324 for clamping the electrode 4, and at least two clamping parts 324 are arranged at equal intervals along the length direction of the fixing plate 323.

[0066] Specifically, in this embodiment, the moving part 31 can be omitted, and only a plurality of clamping parts 324 for clamping the electrode 4 need to be provided on the fixing plate 323.

[0067] It should be noted that the clamping part 324 can be a clip, or any structure that can achieve the effect of clamping the electrode 4.

[0068] Example 5

[0069] like Figure 5 As shown, unlike Embodiment 1, in this embodiment, the first camera 11 and the second camera 12 are symmetrically arranged on both sides of the liquid storage component 2.

[0070] Specifically, the first camera 11 and the second camera 12 are symmetrically arranged on both sides of the electrode 4. Each camera takes a picture of one surface of the electrode 4. The two cameras are arranged in a counter-supporting manner to monitor the process of the two surfaces of the electrode 4 absorbing electrolyte, thereby determining the electrolyte absorption of the electrode 4.

[0071] Example 6

[0072] like Figure 6 As shown, unlike Embodiment 1, in this embodiment, a synchronizing member 325 is provided between the moving part 31 and the fixed part 32, and the two ends of the synchronizing member 325 are fixedly connected to the driving member 313 and the slider 322, respectively.

[0073] Specifically, a synchronizing element 325 is fixedly installed between the driving component 313 and the slider 322, so that when the moving part 31 rises and falls, it drives the fixed part 32 to rise and fall together. The specific working principle is as follows: after the moving part 31 and the fixed part 32 clamp the electrode 4, the supporting plate 312 descends, causing the electrode 4 to come into contact with the electrolyte or increasing the contact area between the electrode 4 and the electrolyte. The supporting plate 312 drives the slider 322 to descend along the sliding rod 321 simultaneously through the synchronizing element 325, so that the abutment plate 314 and the fixed plate 323 are always on the same horizontal plane and always in contact with the electrode 4, ensuring the stability of the electrode 4 clamping. After the test is completed, the electrode 4 rises in the same way.

[0074] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0075] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on this utility model are within the protection scope of this utility model.
