Description

Technical Field

[0001] This application relates to the field of new energy battery technology, specifically to an electrode testing device. Background Technology

[0002] As a core component of new energy batteries such as lithium-ion batteries, the performance of electrodes significantly impacts the battery's energy density, cycle life, and safety. Among these, the wetting properties of the electrode reflect the interaction between the electrode and the electrolyte, directly affecting the battery's energy density and cycle life. Therefore, testing the wetting properties of the electrode is crucial in the battery manufacturing process.

[0003] In existing methods for testing electrode wetting performance, the wetting angle of the electrolyte droplet on the electrode is usually measured using a wetting angle measuring instrument, and the wettability of the electrode is evaluated accordingly.

[0004] However, when using a wetting angle meter to test the performance of electrodes, the wetting angle only reflects the wettability of the electrode surface to the electrolyte, which has limitations and the test results are not comprehensive or accurate enough. Furthermore, the electrolyte wetting speed after being dropped onto the electrode is very fast, requiring a high-speed camera to obtain accurate results. Such devices are complex in structure, difficult to operate, and costly. Therefore, how to accurately test the wetting performance of electrodes using a simple testing device has become a technical problem that needs to be solved. Utility Model Content

[0005] In view of the above problems, this application provides an electrode testing device. When testing the wetting performance of an electrode using this device, it is only necessary to weigh the electrolyte before immersing the electrode in the electrolyte using a weighing component, and to weigh the remaining electrolyte after separating the electrode from the electrolyte using the same weighing component. By comparing the changes in electrolyte weight, the wetting performance of the electrode after immersion in the electrolyte and standing can be determined, resulting in more accurate test results. Furthermore, this electrode testing device has a simple structure, is easy to operate, and has a lower cost.

[0006] One aspect of this application provides an electrode testing apparatus, which includes a container, a weighing component, and a clamping component. The container has a receiving space for holding an electrolyte. The weighing component is connected to the container to weigh the electrolyte in the container. The clamping component includes a fixed part and a movable part connected to each other. The fixed part is used to fix the electrode, and the movable part is movable relative to the container to immerse the electrode in the electrolyte or to separate the electrode from the electrolyte.

[0007] This electrode testing device has a simple structure, is easy to manufacture and process, and has a lower cost. Furthermore, its testing structure is more comprehensive and accurate, requires fewer operating steps, is simpler to operate, requires less training, and allows operators to more easily become proficient in its use.

[0008] In one alternative embodiment, the movable part is provided with a first locking part and a second locking part, with a gap between the first locking part and the second locking part. The first locking part is used to fix the movable part in a first suspended position, so that the electrode is immersed in the electrolyte in the container. The second locking part is used to fix the movable part in a second suspended position, so that the electrode is suspended above the electrolyte.

[0009] In this method, the first locking part and the second locking part can fix the moving part in the first hovering position and the second hovering position respectively, so that the electrode can be placed in the electrolyte without manual control, and the electrode can be suspended in the electrolyte without manual control, making the operation more convenient and saving manpower. In addition, the first hovering position and the second hovering position are always fixed, which improves the repeatability of the test.

[0010] In one alternative embodiment, the container has an upward-facing opening. The movable part is a movable rod that can move axially relative to the opening. One end of the movable rod is connected to a fixed part, allowing the movable rod to drive the electrode, which is fixed by the fixed part, through the opening and immerse it in the electrolyte.

[0011] In this design, the movable part is rod-shaped and moves along the axial direction of the rod. Its movement is simple, requiring little space, resulting in a simple overall structure that is easy to manufacture and install. Furthermore, the position of the electrode can be adjusted with a simple push-pull motion, facilitating operation.

[0012] In one alternative embodiment, the electrode testing device further includes a housing with a movable channel. A movable rod passes through the movable channel, and both a first locking part and a second locking part are rotatable with the movable rod. The first locking part and the second locking part can pass through the movable channel when they are opposite to it.

[0013] In this method, the first and second locking parts only need to rotate with the movable rod to cooperate with the movable channel and fix the movable rod. Its structure is simple, easy to process, and convenient to operate.

[0014] In one alternative configuration, the first locking part is a first crossbar, and the second locking part is a second crossbar.

[0015] The first and second horizontal bars are parallel, or there is an angle between the first and second horizontal bars.

[0016] In this design, the first and second movable parts are respectively configured as a first crossbar and a second crossbar, which has a simple structure and is easy to manufacture and control in terms of dimensions. The first and second crossbars are parallel, which facilitates the alignment and installation of the movable rod and the housing. The included angle between the first and second crossbars reduces the rotational operation required when the movable rod switches between the first and second hovering positions.

[0017] In one alternative, the fixing part includes a spring clip or a magnetic element.

[0018] In this method, whether the electrode is fixed by a spring clip or a magnetic component, the fixing effect is reliable, and the structure is simple and easy to operate.

[0019] In one alternative approach, the weighing assembly includes a weight sensor that is pressed against the bottom of the container.

[0020] This method has a simple and compact structure, is easy to assemble, and can accurately weigh the electrolyte in the container using a weight sensor.

[0021] In an alternative embodiment, the electrode testing apparatus also includes a housing. The housing has a viewing window that faces the clamping components and the container.

[0022] This method allows operators to easily inspect the electrodes and the electrolyte in the container.

[0023] In one alternative embodiment, the electrode testing apparatus also includes a base plate, the bearing surface of which is used to support the container, weighing assembly, clamping assembly, and housing.

[0024] In this method, the bearing surface serves as the positioning reference for the container, weighing component, clamping component, and shell, facilitating the alignment of each component.

[0025] In one alternative approach, the outer shell is detachably attached to the base plate to enclose the container.

[0026] This method can isolate the container from the external environment while making the outer shell easier to disassemble and assemble.

[0027] In the electrode testing device provided in this application embodiment, the movable part of the clamping component can move relative to the container, thereby allowing the electrode fixed by the fixing part to be immersed in the electrolyte contained in the container for settling, and also allowing the electrode to be separated from the electrolyte through movement. When testing the wetting performance of the electrode, it is only necessary to weigh the electrolyte before the electrode is immersed in the electrolyte using the weighing component, and weigh the remaining electrolyte after the electrode is separated from the electrolyte using the weighing component. By comparing the changes in the weight of the electrolyte, the wetting performance of the electrode after immersion in the electrolyte and settling can be obtained, and the test results are more comprehensive and accurate. Furthermore, this electrode testing device has a simple structure, is easy to manufacture and process, and has a lower cost. In addition, the operation steps required when using this electrode testing device are few, the operation is simpler, and no excessive operation training is required, making it easier for operators to become proficient in its use.

Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] The electrode testing device provided in this application embodiment is as follows: Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a schematic diagram of the structure of an electrode testing device provided in an embodiment of this application. Figure 2 This is a cross-sectional view of the movable part of the electrode testing device according to an embodiment of this application when it is in the first hovering position. Figure 3 This is a cross-sectional view of the movable part of the electrode testing device according to an embodiment of this application when it is in the second hovering position. The electrode testing device includes a container 10, a weighing assembly 20, a clamping assembly 30, a base plate 40, and a housing 50.

[0050] The base plate 40 is a component that provides support and positioning for other components. In a specific embodiment, the base plate 40 has a bearing surface for supporting the container 10, the weighing component 20, the clamping component 30, and the outer shell 50, thereby making the bearing surface a positioning reference for the container 10, the weighing component 20, the clamping component 30, and the outer shell 50, facilitating the alignment of the various components.

[0051] Container 10 is a structure used to hold the electrolyte. Container 10 may be made of high-strength, corrosion-resistant materials to ensure that no chemical reaction or leakage occurs when holding the electrolyte. Container 10 has sufficient capacity to hold an appropriate amount of electrolyte, allowing the electrode 60 to be completely immersed in the electrolyte in container 10 and react fully with the electrolyte.

[0052] The container 10 can be configured as a cylindrical chamber, a spherical chamber, or a cubic chamber, without limitation. The size of the container is determined according to the electrode 60 to be tested, as long as the electrode 60 can be fully immersed in the electrolyte contained in the container 10.

[0053] The weighing assembly 20 is a component used to weigh the electrolyte. The weighing assembly 20 is connected to the container 10 to weigh the electrolyte in the container 10. In a specific embodiment, the sensor of the weighing assembly 20 can be pressed or pulled by the container 10 to weigh the electrolyte in the container 10.

[0054] In one optional embodiment, the weighing assembly 20 includes a weight sensor that is pressed against the bottom of the container 10. This method is simple and compact, easy to assemble, and can accurately weigh the electrolyte in the container 10 using the weight sensor.

[0055] The weighing component 20 can be an electronic scale or similar structure. In addition to the weight sensor, the weighing component can also include a display for showing the weight, a power supply, and other specific parts, without any restrictions.

[0056] like Figure 3 As shown, the clamping assembly 30 is a component used to fix the electrode 60, immerse the electrode 60 in the electrolyte, and separate the electrode 60 from the electrolyte. The clamping assembly 30 includes a fixed part 31 and a movable part 32 connected together. The fixed part 31 is used to fix the electrode 60, and the movable part 32 can move relative to the container 10, thereby moving the fixed part 31 relative to the container 10 to immerse the electrode 60 in the electrolyte or to separate the electrode 60 from the electrolyte.

[0057] The fixing part 31 can have many structural forms. For example, the fixing part 31 can be configured as a clamping structure, such as including a spring clip to clamp the electrode 60 and fix it. The fixing part 31 can also be configured as a magnetic structure, such as including a magnetic element to attract the electrode 60 and fix it. Whether the fixing part 31 fixes the electrode 60 by a spring clip or a magnetic element, the fixing effect is reliable, and the structure is simple and easy to operate.

[0058] The electrode 60 fixed by the fixing part 31 is a sample for testing. The shape of the electrode 60 can be a cut circle, square, etc., and the size of the electrode 60 can also be freely set according to the requirements. In order to facilitate reliable fixing of the electrode 60, the fixing part 31 can be set as an adjustable structure, so that the fixing part 31 can fix various electrodes 60 with different shapes and sizes.

[0059] The fixed part 31 and the movable part 32 can be connected by welding, plugging, integral molding or other methods so that the fixed part 31 can move synchronously with the movable part 32.

[0060] There are many structural forms of the movable part 32. For example, the movable part 32 can be configured as a retractable, flip-able, or translational structure. The movable part 32 can be moved by a motor, cylinder, or manual operation to drive the fixed part 31 to move closer to or away from the electrolyte, thereby driving the electrode 60 to be immersed in or separated from the electrolyte.

[0061] The movable part 32 should have a sufficient range of motion to ensure that the electrode 60 has enough space to move, allowing it to be fully immersed in the electrolyte for settling. The movable part 32 can also separate the electrode 60 from the electrolyte, i.e., remove the electrode 60 from the electrolyte, and can also suspend the electrode 60 above the electrolyte to collect electrolyte droplets adhering to the electrode 60, thereby making the test results more accurate.

[0062] When testing the wetting performance of electrode 60 using this electrode testing device, an appropriate amount of electrolyte should first be poured into container 10, and the initial weight of the electrolyte in container 10 should be weighed using weighing component 20. Then, electrode 60 is fixed by fixing part 31 of clamping component 30, and electrode 60 is moved by moving part 32 to immerse it in electrolyte and stand for a preset time. After that, electrode 60 is removed from electrolyte by moving part 32 and suspended above electrolyte. When no more electrolyte drips from electrode 60, the residual weight of electrolyte in container 10 is weighed using weighing component 20. The initial weight and the residual weight are compared, and the two values ​​are subtracted to know the weight of electrolyte absorbed by electrode within the preset time, thereby obtaining the wetting performance of electrode 60 within the preset time.

[0063] The electrode testing device requires fewer operating steps and is simpler to use, requiring minimal training and allowing operators to quickly become proficient. The test results obtained using this device accurately reflect the wetting performance of electrode 60 when it is immersed in the electrolyte, providing more precise results and offering greater guidance for actual production. Furthermore, this electrode testing device has a simple structure, is easy to manufacture, and has a lower cost, achieving the goal of accurately testing the wetting performance of electrode 60 using a simple testing device.

[0064] In this embodiment, the movable part 32 is movable relative to the container 10, thereby moving the electrode 60 so that it can be immersed in the electrolyte and separated from the electrolyte for testing the wetting performance of the electrode 60. To keep the electrode 60 stationary in the electrolyte and suspended above the electrolyte, a first locking part 33 and a second locking part 34 can be provided on the movable part 32 to fix the movable part 32 in different positions, allowing the electrode 60 to be stationary in the electrolyte or suspended above the electrolyte.

[0065] An optional approach is as follows Figure 2 , Figure 3 and Figure 4 As shown, Figure 4 This is a schematic diagram of the clamping assembly of the electrode testing device according to an embodiment of this application, showing the structure when the electrode is fixed in place by the fixing part. The movable part 32 is provided with a first locking part 33 and a second locking part 34, with a gap between them. The first locking part 33 is used to fix the movable part 32 in a first suspended position, so that the electrode 60 is suspended and immersed in the electrolyte in the container 10. The second locking part 34 is used to fix the movable part 32 in a second suspended position, so that the electrode 60 is suspended above the electrolyte.

[0066] Both the first locking part 33 and the second locking part 34 can restrict the movement of the movable part 32, thereby fixing the movable part 32 in the first hovering position and the second hovering position respectively. There is a gap between the first locking part 33 and the second locking part 34, so that the first locking part 33 and the second locking part 34 can perform their fixing functions respectively without affecting each other.

[0067] There are many structural forms for the first locking part 33 and the second locking part 34. For example, the first locking part 33 and the second locking part 34 can be configured as a snap-fit ​​structure, a blocking structure, a threaded structure, etc., as long as the first locking part 33 and the second locking part 34 can perform the fixing function.

[0068] In this method, the first locking part 33 and the second locking part 34 can fix the movable part in the first hovering position and the second hovering position respectively, so that the electrode 60 can be placed in the electrolyte without manual control, and the electrode 60 can be suspended above the electrolyte without manual control, making the operation more convenient and saving manpower. In addition, the first hovering position and the second hovering position are always fixed, which improves the repeatability of the test.

[0069] The movable part 32 can be configured as a movable rod, movable plate, or other structure. For example, a specific method is as follows: Figure 2 and Figure 3 As shown, container 10 has an upward-facing opening. The movable part 32 is a movable rod that can move along its axial direction relative to the opening. One end of the movable rod is connected to the fixed part 31, so that the movable rod can drive the electrode 60 fixed by the fixed part 31 to pass through the opening and be immersed in the electrolyte.

[0070] In this configuration, the container 10 has an upward-facing opening, and one end of the movable rod is connected to the fixed part 31. When the movable rod moves along its axial direction, it can cause the electrode 60 fixed by the fixed part 31 to be immersed in or separated from the electrolyte. The movable rod can be specifically configured as a cylindrical rod, a prism rod, etc. The movable rod can also be configured as a hollow rod or a solid rod, etc., without specific limitations.

[0071] Specifically, such as Figure 2 and Figure 3 As shown, the movable rod can be a vertical rod located above the container 10. The bottom end of the movable rod is connected to the fixed part 31. When the movable rod moves downward, it drives the electrode 60 through the opening and immerses it in the electrolyte. The first locking part 33 keeps the electrode 60 stationary in the electrolyte. When the movable rod moves upward, it pulls the electrode 60 out of the electrolyte. The second locking part 34 suspends the electrode 60 above the electrolyte, allowing the electrolyte adhering to the electrode 60 to drip into the container 10, ensuring the accuracy of the test results.

[0072] In this design, the movable part 32 is rod-shaped and moves along the axial direction of the rod. Its movement is simple, requiring little space, resulting in a simple overall structure that is easy to manufacture and install. Furthermore, the position of the electrode 60 can be adjusted with a simple push-pull motion, facilitating operation.

[0073] There are many ways to fix the movable rod by the first locking part 33 and the second locking part 34. For example, a blocking structure can be set on the path of the first locking part 33 and the second locking part 34 as the movable rod moves. The blocking structure can be part of the outer shell 50 or a separate component.

[0074] For example, one alternative approach is as follows: Figure 2 and Figure 3As shown, the electrode testing device also includes a housing 50, on which a movable channel 51 is provided. A movable rod can pass through the movable channel 51. Both the first locking part 33 and the second locking part 34 can rotate with the movable rod. When the first locking part 33 is opposite to the movable channel 51, it can pass through the movable channel 51. When the first locking part 33 and the movable channel 51 are intersected, it can be blocked by the housing 50 to fix the movable rod in a first suspended position. When the second locking part 34 is opposite to the movable channel 51, it can pass through the movable channel 51. When the second locking part 34 and the movable channel 51 are intersected, it can be blocked by the housing 50 to fix the movable rod in a second suspended position.

[0075] The movable channel 51 is a hole or slot opened on the housing 50 for the movable rod to pass through, that is, the movable channel 51 allows the movable rod to perform necessary lifting and lowering movements during the test. However, the first locking part 33 and the second locking part 34 are only opposite to the movable channel 51 at a specific angle. Only at this time can the first locking part 33 and the second locking part 34 pass through the movable channel 51, so that the movable rod can continue to move.

[0076] At other angles, the first locking part 33 and the second locking part 34 will intersect with the movable channel 51, thus blocking their passage. The first locking part 33 can fix the movable rod in the first hovering position when blocked. The second locking part 34 can fix the movable rod in the second hovering position when blocked.

[0077] In this method, the first locking part 33 and the second locking part 34 only need to rotate with the movable rod to cooperate with the movable channel 51 to fix the movable rod. Its structure is simple, easy to process, and convenient to operate.

[0078] The first movable part 32 and the second movable part 32 can also be configured as rod-shaped, block-shaped, etc. One optional method is as follows: Figure 2 , Figure 3 and Figure 4 As shown, the first locking part 33 is the first crossbar, and the second locking part 34 is the second crossbar. The first crossbar and the second crossbar are parallel, or there is an angle between the first crossbar and the second crossbar.

[0079] In this configuration, the first movable part 32 and the second movable part 32 are respectively configured as a first crossbar and a second crossbar, which have a simple structure and are easy to process and control in terms of dimensions. The first crossbar and the second crossbar are parallel, which facilitates the alignment and installation of the movable rod and the housing 50. The first crossbar and the second crossbar have an included angle, which reduces the rotation operation required when the movable rod switches between the first hovering position and the second hovering position.

[0080] In this embodiment, the outer shell 50 serves to enclose the internal components such as the container 10 to prevent external influences during the testing process. There are many ways to install the outer shell 50; for example, the outer shell 50 can be detachably mounted on the base plate 40 using a snap-fit ​​or similar structure. Alternatively, the outer shell 50 can also be... Figure 1 The detachable clip is attached to the base plate 40 to surround the container 10, thereby isolating the container 10 from the external environment and making the outer shell 50 easier to assemble and disassemble.

[0081] Furthermore, the outer casing 50 can also be like Figure 1 and Figure 5 As shown, Figure 5 This is a schematic diagram of the outer casing of the electrode testing device according to an embodiment of this application. The casing 50 has a viewing window 52, ​​which faces the clamping assembly 30 and the container 10, allowing the operator to view the electrode 60 and the electrolyte in the container 10. The viewing window 52 can be an opening in the casing 50 or a transparent window opening; no limitation is made here.

[0082] In summary, in the electrode testing device described above, the movable part of the clamping component can move relative to the container, thereby allowing the electrode, fixed by the fixing part, to be immersed in the electrolyte in the container for settling, and also allowing the electrode to be separated from the electrolyte through movement. When testing the wetting performance of the electrode, it is only necessary to weigh the electrolyte before immersing the electrode in the electrolyte using the weighing component, and to weigh the remaining electrolyte after separating the electrode from the electrolyte using the weighing component. By comparing the changes in electrolyte weight, the wetting performance of the electrode after immersion in the electrolyte and settling can be determined, resulting in more comprehensive and accurate test results. Furthermore, this electrode testing device has a simple structure, is easy to manufacture, and has lower costs. In addition, the operation steps required when using this electrode testing device are few, making operation simpler and requiring less training, allowing operators to easily become proficient in its use.
