[0041] In the production process of lithium-ion batteries, the water content of the electrolyte is an important parameter to characterize the decomposition of lithium salts. A high water content will cause the decomposition of lithium salts and the battery cell to swell. The decomposition product hydrofluoric acid (HF) will damage the SEI film, resulting in poor cycle performance. At the same time, hydrofluoric acid will react with the impurities in the electrode, causing the battery cell to produce gas. Therefore, it is necessary to test the water content and hydrofluoric acid (HF) content of the electrolyte before injection.

[0042] At present, the water content and hydrofluoric acid (HF) content of electrolyte in the filling process are generally detected by manual detection method, that is, samples are taken manually from the head and tail of the filling tank and each filling machine station, and a test order number is written and sent to the testing laboratory for queue testing. This manual sampling and testing method leads to the defects of large workload, low convenience and long test waiting period for electrolyte testing.

[0043] Based on the above problems, the present application designs an electrolyte detection device, system and control method thereof, wherein the electrolyte storage device is connected to the moisture detection device and the hydrofluoric acid content detection device through pipelines, and then the transmission and quantitative control of the electrolyte are controlled by the on-off control component, so as to realize the automatic detection of the electrolyte, thereby reducing the workload and detection time of the electrolyte detection, improving the convenience of the electrolyte detection, and avoiding the errors caused by the interference of the manual detection and the sampling and sample delivery environment. In addition, the present scheme also realizes the electrolyte detection by quantitatively extracting the electrolyte from different points of the electrolyte storage device, thereby improving the detection reliability. At the same time, the present scheme also automatically completes the waste liquid discharge and the introduction of pure water for cleaning after the test is completed, thereby avoiding the mutual interference of the detection liquid and improving the detection accuracy. Furthermore, the present scheme can also be equipped with liquid level monitoring for the reagents and waste liquids, and can issue a warning of insufficient reagents and a warning of the waste liquid page exceeding the warning, so as to timely remind the reagents to be replenished and the waste liquid to be discharged in time.

[0044] Based on the above ideas, the present application first provides an electrolyte detection device, such as Figure 1 As shown, the electrolyte detection equipment includes a multifunctional testing device 10, which includes a moisture detection device 110 and a hydrofluoric acid content detection device 120. The moisture detection device 110 is used to detect the moisture content in the electrolyte. For example, the moisture detection device 110 can use Karl Fischer reagent to detect the water content of the electrolyte. The hydrofluoric acid content detection device 120 is used to detect the hydrofluoric acid content in the electrolyte. For example, the hydrofluoric acid content detection device 120 can detect the hydrofluoric acid content in the electrolyte by chemical titration.

[0045] Please continue to refer to Figure 1 The moisture detection device 110 and the hydrofluoric acid content detection device 120 are both connected to the electrolyte storage device 30 through the electrolyte pipeline 20, and the electrolyte pipeline 20 is provided with an on-off control component 40.

[0046] In the electrolyte detection equipment designed as above, the on-off control component 40 can control whether the electrolyte in the electrolyte pipeline 20 flows or not by opening or closing itself. When performing detection, the on-off control component 40 can be opened, so that the electrolyte in the electrolyte storage device 30 flows to the moisture detection device 110 and the hydrofluoric acid content detection device 120 respectively through the electrolyte pipeline 20, thereby performing moisture detection and hydrofluoric acid detection on the electrolyte in the electrolyte storage device 30, thereby realizing automatic detection of the electrolyte.

[0047] The electrolyte detection equipment designed as above, this scheme connects the electrolyte storage device to the moisture detection device and the hydrofluoric acid content detection device through pipelines, and then controls the transmission and quantitative control of the electrolyte through the on-off control component, thereby realizing automatic detection of the electrolyte, thereby reducing the workload and detection time of the electrolyte detection, improving the convenience of the electrolyte detection, and avoiding errors caused by manual detection and interference from the sampling and delivery environment.

[0048] As a possible implementation, Figure 2 As shown, the electrolyte storage device 30 designed in this scheme may include an electrolyte storage tank 310 and a liquid injection machine 320, the electrolyte pipeline 20 may include a first pipeline 210 and a second pipeline 220, the electrolyte storage tank 310 is connected to the moisture detection device 110 and the hydrofluoric acid content detection device 120 through the first pipeline 210, and the liquid injection machine 320 is connected to the moisture detection device 110 and the hydrofluoric acid content detection device 120 through the second pipeline 220; the on-off control component 40 includes a first on-off control component 410 and a second on-off control component 420; the first on-off control component 410 is arranged on the first pipeline 210, and the second on-off control component 420 is arranged on the second pipeline 220.

[0049] In the above-mentioned implementation mode, this scheme can detect both the electrolyte storage tank 310 and the injection machine 320, and the electrolyte pipelines used in the electrolyte storage tank 310 and the injection machine 320 are different, thereby avoiding mutual interference between the electrolyte components on the electrolyte storage tank 310 and the injection machine 320, thereby improving the accuracy of electrolyte detection.

[0050] Specifically, Figure 3 As shown, the first pipeline 210 designed in this scheme may include a first branch pipeline 2110 and a second branch pipeline 2120. The top of the electrolyte storage tank 310 is connected to the moisture detection device 110 and the hydrofluoric acid content detection device 120 respectively through the first branch pipeline 2110, and the bottom of the electrolyte storage tank 310 is connected to the moisture detection device 110 and the hydrofluoric acid content detection device 120 respectively through the second branch pipeline 2120.

[0051] Since the composition of the electrolyte at different positions in the electrolyte storage tank 310 may be different, the above-mentioned implementation method of the present scheme connects the top and the bottom of the electrolyte storage tank 310 respectively through the first branch pipe 2110 and the second branch pipe 2120, so that the electrolyte in different parts of the electrolyte storage tank 310 can enter the moisture detection device 110 and the hydrofluoric acid content detection device 120 through the first branch pipe 2110 and the second branch pipe 2120 for detection, thereby realizing the detection of the electrolyte water content and the hydrofluoric acid content at different positions in the electrolyte storage tank 310, thereby improving the accuracy of the detection of the electrolyte water content and the hydrofluoric acid content in the electrolyte storage tank 310.

[0052] As a specific implementation method, Figure 4 As shown, the first branch pipeline 2110 and the second branch pipeline 2120 designed in this solution can be as follows Figure 4 The pipeline A, pipeline B, pipeline C, pipeline D and pipeline F are shown, wherein the first end of pipeline A is connected to the top of the electrolyte storage tank 310, the second end of pipeline A is connected to the first end of pipeline B, the first end of pipeline C is connected to the bottom of the electrolyte storage tank 310, the second end of pipeline C is also connected to the first end of pipeline B, the second end of pipeline B is connected to the moisture detection device 110 through pipeline D, and the second end of pipeline B is also connected to the hydrofluoric acid content detection device 120 through pipeline F.

[0053] In the implementation mode of the above-mentioned design, the electrolyte flowing out from the top of the electrolyte storage tank 310 can flow to the moisture detection device 110 through the pipeline D, and flow to the hydrofluoric acid content detection device 120 through the pipeline F, and the electrolyte at the bottom of the electrolyte storage tank 310 can also be transmitted to the moisture detection device 110 through the pipeline D, and transmitted to the hydrofluoric acid content detection device 120 through the pipeline F. In this way, the electrolyte at the top and bottom of the electrolyte storage tank 310 share the pipeline D and the pipeline F, thereby realizing pipeline sharing and achieving the purpose of saving pipeline costs.

[0054] In an optional implementation of this embodiment, if Figure 4 As shown, the electrolyte detection equipment designed in this scheme may also include a first water pump 50, which can be set on the pipeline B. The first water pump 50 can extract the electrolyte from the top or bottom of the electrolyte storage tank 310, thereby applying power to the extracted electrolyte, so that the electrolyte is transmitted to the moisture detection device 110 through the pipeline D, and is transmitted to the hydrofluoric acid content detection device 120 through the pipeline F.

[0055] In the implementation method of the above-mentioned design, this solution accelerates the flow rate of the electrolyte in the electrolyte storage tank to the moisture detection device and the hydrofluoric acid content detection device through the first water pump, thereby improving the detection efficiency of the electrolyte.

[0056] In an optional implementation of this embodiment, if Figure 4As shown, the first on-off control component 410 designed in the present solution may specifically include a first valve A1, a second valve A2, a third valve A3 and a fourth valve A4. The first valve A1 is arranged in the pipeline A, the second valve A2 is arranged in the pipeline C, the third valve A3 is arranged in the pipeline D, and the fourth valve A4 is arranged in the pipeline F. In this way, the flow rate control and flow direction control of the electrolyte flowing out of the electrolyte storage tank 310 can be achieved by controlling the multiple valves.

[0057] For example, assuming that the electrolyte at the top of the electrolyte storage tank 310 needs to be tested for moisture. In this case, the present solution only needs to control the first valve A1 and the third valve A3 to be opened, and the second valve A2 and the fourth valve A4 to be closed. In this way, the electrolyte at the top of the electrolyte storage tank 310 can be transmitted to the moisture detection device 110 through the pipeline A, the pipeline B and the pipeline D for moisture detection; for another example, assuming that the electrolyte at the bottom of the electrolyte storage tank 310 needs to be tested for moisture and hydrofluoric acid content. In this case, the present solution controls the first valve A1 to be closed, and the second valve A2, the third valve A3 and the fourth valve A4 to be opened. In this way, the electrolyte at the bottom of the electrolyte storage tank can be transmitted to the moisture detection device 110 and the hydrofluoric acid content detection device 120 through the pipeline C, the pipeline B, the pipeline D and the pipeline F respectively to realize moisture and hydrofluoric acid content detection.

[0058] In the implementation scheme of the above-mentioned design, multiple valves are arranged in multiple pipes, so that the electrolyte at the top and / or bottom of the electrolyte storage tank 310 can realize arbitrary detection control of moisture detection and hydrofluoric acid detection through the control of multiple valves, thereby improving the controllability of electrolyte detection.

[0059] Of course, the first branch pipe and the second branch pipe designed in this solution can be in any other form, as long as the electrolyte at the top and bottom of the electrolyte storage tank 310 can be transmitted to the moisture detection device 110 and the hydrofluoric acid content detection device 120 respectively. For example, Figure 5 As shown, the first branch pipe 2110 and the second branch pipe 2120 can be as follows Figure 5 In the form of pipeline A, pipeline B, pipeline C, pipeline D, pipeline E and pipeline F shown, the top of the electrolyte storage tank 310 is connected to the first end of pipeline A, the second end of pipeline A is connected to the first end of pipeline B and the first end of pipeline C, the second end of pipeline B is connected to the moisture detection device 110, and the second end of pipeline C is connected to the hydrofluoric acid content detection device 120; the bottom of the electrolyte storage tank 310 is connected to the first end of pipeline D, the second end of pipeline D is connected to the first end of pipeline E and the first end of pipeline F, the second end of pipeline E is connected to the moisture detection device 110, and the second end of pipeline F is connected to the hydrofluoric acid content detection device 120.

[0060] In an optional implementation of this embodiment, if Figure 6 As shown, the liquid injection machine 320 includes multiple liquid injection stations 3210. In this case, the second pipeline 220 designed in this scheme may include a station transmission pipeline 2210 and a third branch pipeline 2220.

This solution can control the volume of reagent transmitted from the reagent pipeline port 1110B to the reaction tank 1110 by controlling the reagent control valve 1130, thereby realizing quantitative extraction of the reagent; in the case of realizing quantitative extraction of the reagent, this solution can control the volume of electrolyte entering the reaction tank 1110 by controlling the opening time of the on-off control component 40 in the electrolyte pipeline 20, thereby realizing quantitative extraction of the electrolyte to be detected, and then the volume of electrolyte and reagent entering the reaction tank can be controlled, realizing quantitative and sufficient reaction of the reagent and the electrolyte, and then the water content in the electrolyte can be calculated by obtaining the amount of electricity generated by electrolysis, thereby improving the accuracy and controllability of electrolyte detection.

[0076] Furthermore, the present solution may be provided with a liquid level monitoring device in the reagent storage tank 1120 to monitor the reagent liquid level in the reagent storage tank 1120. When the reagent liquid level in the reagent storage tank 1120 is less than the monitoring liquid level, an alarm is issued to remind the staff to add reagents. Among them, the moisture detection reagent used in the present solution may be a Karl Fischer reagent. Specifically, the liquid level monitoring device may be an infrared sensor, which is arranged on a side wall in the reagent storage tank 1120. When the reagent liquid level in the reagent storage tank is below the infrared detection light emitted by the infrared sensor, the infrared sensor sends an alarm signal, thereby realizing an alarm reminder.

[0077] In an optional implementation manner of the present embodiment, the bottom of the reaction pool 1110 designed in the present scheme can be connected to the waste liquid discharge pipe 91. After the electrolyte and detection reagent testing in the reaction pool 1110 is completed, the present scheme can control the waste liquid control valve 92 to open, so that the mixed waste liquid formed by the electrolyte and detection reagent in the reaction pool 1110 is discharged through the waste liquid discharge pipe 91, thereby avoiding the waste liquid from affecting the next electrolyte detection.

[0078] In an optional implementation of this embodiment, if Fig.10 As shown, the reaction pool 1110 designed in this solution is also provided with a clean water port 1110C, which can be connected to the clean water pipeline 80 described above.

On this basis, the potentiometric titrator 1220 can control the reagent capacity added in the reagent addition pipeline 1220A. When the potentiometric titrator 1220 automatically determines that the reaction has reached the end point, it controls the reagent to stop adding. When the reagent stops adding, the potentiometric titrator 1220 can automatically obtain the liquid level difference before and after the reagent is added to the reagent addition pipeline, and then obtain the capacity difference before and after the reagent is added in the reagent addition pipeline 1220A, and obtain VV 0 , and then the hydrofluoric acid content can be calculated by the above formula.

[0094] As for step S1410, it is described above that the control device designed in the present scheme can perform quantitative control on the addition of the moisture detection reagent of the moisture detection device. For example, the control device can communicate with the reagent control valve, and realize the quantitative addition of the moisture detection reagent by controlling the opening time of the reagent control valve. In this case, the present scheme can control the opening of the reagent control valve to transmit a fixed volume of moisture detection reagent to the moisture detection device, so that the moisture detection reagent reacts with the electrolyte entering the moisture detection device, so that the amount of electricity generated by the electrolysis of the moisture detection device is proportional to the moisture content, and the moisture content can be calculated through the linear relationship between the amount of electricity and the moisture content.

[0095] As for step S1420, it is described above that the potentiometric titrator can quantitatively control the reagent addition of the hydrofluoric acid content detection device.

[0096] The electrolyte detection control method designed above connects the electrolyte storage device to the moisture detection device and the hydrofluoric acid content detection device through pipelines, and then controls the transmission and quantitative control of the electrolyte through the on-off control component, thereby realizing automatic detection of the electrolyte, thereby reducing the workload and detection time of the electrolyte detection, improving the convenience of the electrolyte detection, and avoiding errors caused by manual detection and interference from the sampling and delivery environment.

[0098] Among them, the completion of the current detection by the moisture detection device can be that the moisture detection reagent and the electrolyte in the reaction cell fully complete the reaction. The characterization of the fully completed reaction can be determined by collecting the number of times the moisture detection reagent is added, that is, the capacity of the electrolyte added in the moisture detection device is fixed, and the capacity of the moisture detection reagent required for the fixed capacity of the electrolyte to complete the full reaction is also fixed. In this regard, this scheme can add enough moisture detection reagent at one time, or it can be added in multiple times. The number of additions in this scheme can be set in advance. After adding the electrolyte once, this scheme can determine the number of additions of the moisture detection reagent. If the number of additions set in advance is reached, it indicates that the reaction is fully completed, and the above-mentioned waste liquid discharge and cleaning control can be performed.
