Description

Technical Field

[0001] The present invention relates to the technical field of electrolyte testing, and in particular to an electrolyte characterization testing workstation, an electrolyte characterization testing system and an electrolyte characterization testing method. Background Art

[0002] With the vigorous development of the new energy industry, electrolytes have a broad market space and industrial scale. However, in the face of increasingly fierce competition and new technological development trends, it is necessary to tackle the new requirements of electrolytes put forward by new material systems.

[0003] Currently, during the research and development of electrolytes, electrolyte testing needs to be carried out in a water-free and oxygen-free environment (such as a glove box, dry room, etc.). The electrolyte is extracted and measured using tools such as manual pipettes, small spoons, tweezers, and balances, and then the electrolyte is characterized and tested through manual operation of related instruments and equipment.

[0004] Lithium battery electrolyte is a complex system with multi-dimensional variables and a large design space. During the research and development of electrolyte, there are some industry pain points: (1) High-throughput experiments are required, and manual operation is inefficient. During the development and research of electrolytes, manual testing of a large number of different formulas is mainly relied on, which is inefficient. In addition, the electrolyte testing needs to be carried out in an environment without water and oxygen (such as a glove box, dry room, etc.), which makes manual operation extremely inconvenient and further reduces the testing efficiency. (2) Complex characterization tests are required to understand the characteristics of the electrolyte. The electrolyte is a complex system with multiple variables. It is difficult to describe the structure-activity relationship between each component and the electrolyte performance. It is necessary to conduct various targeted characterization tests to understand the main characteristics of various electrolyte formulas, so as to explore better quality electrolytes and the structure-activity relationship between each component and the electrolyte performance; (3) There is no mature laboratory automation solution. Modular manufacturers are expensive and suitable for specific functional scenarios (such as ChemSpeed); automation integrators are more focused on biomedicine and other fields and lack understanding of electrolyte research and development (such as Jingtai and Kejing).

[0020] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all 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.

[0021] Traditional technologies cannot perform automated characterization tests on electrolytes.

[0022] Based on this, the electrolyte characterization test workstation of the present invention can realize unmanned electrolyte characterization testing through automated design, and the characterization test process is precisely controlled, which greatly improves the test efficiency. It can independently complete repeated tests, collect standardized test data, and realize high-throughput and standardized full data chain management.

[0023] To facilitate understanding of this embodiment, an electrolyte characterization test workstation disclosed in an embodiment of the present invention is first introduced in detail.

[0024] Example 1: Figure 1 FIG. 1 is a schematic structural diagram of an electrolyte characterization test workstation according to an embodiment of the present invention. Figure 1 As shown, it includes: a six-axis manipulator, a visual judgment module, a centralized liquid dispensing module, a seventh-axis linear motor module, a characterization test module and an anhydrous and oxygen-free working room, wherein the six-axis manipulator, the visual judgment module, the centralized liquid dispensing module, the seventh-axis linear motor module and the characterization test module are arranged in the anhydrous and oxygen-free working room; The six-axis manipulator is mounted on the seventh-axis linear motor module and can move along the seventh-axis line of the seventh-axis linear motor module. The six-axis manipulator is used to, in cooperation with the seventh-axis linear motor module, pick up the bottled electrolyte to be tested in the anhydrous and oxygen-free working chamber and place the bottled electrolyte to be tested on the visual judgment module. A visual determination module is used to take photos of the bottom and front surfaces of the bottled electrolyte to be tested, and identify the miscibility of the bottled electrolyte to be tested based on the bottom and front images obtained by taking photos, thereby obtaining the miscibility of the bottled electrolyte to be tested; The six-axis manipulator is also used to pick up the bottled electrolyte to be tested and transfer it to the centralized liquid dispensing module in cooperation with the seventh-axis linear motor module when the miscibility state meets the requirements; A centralized liquid separation module is used to pipette and separate the bottled electrolyte to be tested to obtain a preset number of reagent bottles containing the electrolyte to be tested; The six-axis manipulator is also used to clamp each reagent bottle to the corresponding characterization test module for characterization testing in cooperation with the seventh-axis linear motor module, thereby obtaining characterization test data.

[0025] In an embodiment of the present invention, the seventh-axis straight line of the seventh-axis linear motor module is placed along the long side of the anhydrous and oxygen-free working chamber. The above-mentioned bottled electrolyte to be tested is specifically the electrolyte to be tested contained in a transparent glass bottle made of low borosilicate. The above-mentioned visual judgment module includes: an image acquisition device and a processor.

Then, the miscibility state recognition model in the processor performs miscibility state recognition on the bottom and front images to obtain the solid-liquid miscibility result and the liquid-liquid miscibility result (i.e., the miscibility state of the bottled electrolyte to be tested); the processor may also pre-store an image library of solid-liquid immiscibility, an image library of solid-liquid miscibility, an image library of liquid-liquid immiscibility, and an image library of liquid-liquid miscibility. The bottom and front images obtained by taking pictures are calculated for similarity with the images in the above-mentioned library, and the miscibility label corresponding to the image with the highest similarity is used as the miscibility state of the bottled electrolyte to be tested corresponding to the bottom and front images.

[0026] The visual judgment module replaces the human eye, with a far higher precision than the human eye can detect fine particles. When the miscibility is solid-liquid or liquid-liquid, the miscibility is determined to meet the requirements. When the solid-liquid or liquid-liquid immiscible, the miscibility is determined to not meet the requirements, and subsequent pipetting, dispensing, and characterization testing are not performed.

[0027] In an embodiment of the present invention, an electrolyte characterization test workstation is provided, comprising: a six-axis manipulator, a visual judgment module, a centralized liquid dispensing module, a seventh-axis linear motor module, a characterization test module and an anhydrous and oxygen-free working room, wherein the six-axis manipulator, the visual judgment module, the centralized liquid dispensing module, the seventh-axis linear motor module and the characterization test module are arranged in the anhydrous and oxygen-free working room; the six-axis manipulator is installed on the seventh-axis linear motor module, and the six-axis manipulator can move on the seventh-axis straight line of the seventh-axis linear motor module; the six-axis manipulator is used to clamp the bottled electrolyte to be tested into the anhydrous and oxygen-free working room with the cooperation of the seventh-axis linear motor module, and place the bottled electrolyte to be tested on the visual judgment module. A visual judgment module; a visual judgment module for taking pictures of the bottom and front of the bottled electrolyte to be tested, and identifying the mutual solubility state based on the bottom image and the front image obtained by taking pictures, to obtain the mutual solubility state of the bottled electrolyte to be tested; a six-axis manipulator is also used to clamp the bottled electrolyte to be tested to the centralized liquid separation module with the cooperation of the seventh-axis linear motor module when the mutual solubility state meets the requirements; the centralized liquid separation module is used to pipette and separate the bottled electrolyte to be tested to obtain a preset number of reagent bottles containing the electrolyte to be tested; the six-axis manipulator is also used to clamp each reagent bottle to the corresponding characterization test module for characterization testing with the cooperation of the seventh-axis linear motor module, and then obtain characterization test data.

[0028] The above content briefly introduces the electrolyte characterization test workstation of the present invention. The specific contents involved are described in detail below.

[0029] In an optional embodiment of the present invention, the centralized liquid dispensing module includes: a three-axis XYZ servo module, an automatic liquid transfer pump, and a servo rotary electric gripper; The automatic pipetting pump and servo rotary electric gripper are installed on the Z axis of the three-axis XYZ servo module; the three-axis XYZ servo module is used to achieve movement in all directions; Servo-rotating electric claw, used to open and close the lid of the reagent bottle; The automatic pipetting pump is used to dispense the electrolyte to be tested from the bottled electrolyte to the reagent bottle. It must be used in conjunction with a pipette tip, which is a disposable consumable.

[0030] In an optional embodiment of the present invention, the characterization test module includes: a Raman test module, a conductivity test module, a saturated vapor pressure test module and a viscosity test module. Figure 1 ; The conductivity test module includes: conductivity cleaning module, conductivity drying module, high temperature test module and low temperature test module.

[0031] In an alternative embodiment of the present invention, reference Figure 1 , also includes: electrolyte reagent bottle rack, electrolyte NG product rack, Raman reagent bottle rack, conductivity reagent bottle rack, saturated vapor pressure reagent bottle rack, viscosity reagent bottle rack, pipette tip rack ( Figure 1 Not shown, placed inside the centralized dispensing module), discarded pipette tip recovery rack ( Figure 1 Not shown, placed inside the centralized liquid separation module); The electrolyte reagent bottle rack is set adjacent to the visual judgment module and is used to place bottled electrolyte to be tested; The electrolyte NG material rack is set adjacent to the visual judgment module and is used to place bottled electrolyte to be tested that does not meet the miscibility requirements; The Raman reagent bottle rack is arranged adjacent to the Raman test module and is used to place the Raman test reagent bottles; The conductivity reagent bottle rack is arranged adjacent to the conductivity test module and is used to place reagent bottles for the conductivity test; The saturated vapor pressure reagent bottle rack is arranged adjacent to the saturated vapor pressure test module and is used to place reagent bottles for saturated vapor pressure testing; The viscosity reagent bottle rack is arranged adjacent to the viscosity test module and is used to place reagent bottles for viscosity testing; The pipette tip rack is used to store the pipette tips used with the automatic pipetting pump and is placed in the centralized dispensing module; The waste pipette tip recovery rack is used to recover waste pipette tips and place them in the centralized dispensing module.

[0032] Specifically, the pipette tip is installed on an automatic pipetting pump for pipetting. It is a disposable material and needs to be recycled after use.

[0033] In an alternative embodiment of the present invention, reference Figure 1 , further comprising: an aluminum foil packaging module; The aluminum foil packaging module is used to package the remaining bottled electrolyte to be tested after pipetting and separation for recycling.

[0034] In an alternative embodiment of the present invention, reference Figure 1 , further comprising: a material stacking tray; The material stacking tray is used to place reagent bottles and test consumables entering the anhydrous and oxygen-free working room and to recycle used reagent bottles and test consumables.

[0035] Specifically, the above-mentioned test consumables can be pipette tips.

[0036] In an optional embodiment of the present invention, the present invention further comprises: a host computer located outside the anhydrous and oxygen-free working room; The host computer is connected to the six-axis manipulator, visual judgment module, centralized liquid dispensing module, seventh-axis linear motor module, and characterization test module respectively to control the operation of the electrolyte characterization test workstation.

[0037] In order to facilitate a better understanding of the electrolyte characterization test workstation of this embodiment, the following Figure 1 A detailed description of its working process: Multiple bottles of electrolyte to be tested enter the anhydrous and oxygen-free workroom through the electrolyte transition chamber. A six-axis robotic arm, replacing human hands, picks up these bottles and temporarily stores them on the electrolyte reagent rack. The robotic arm then picks up a bottle of electrolyte to be tested from the rack and passes it to the visual recognition module, which identifies the solid-liquid and liquid-liquid miscibility of the bottled electrolyte to determine its miscibility. In this process, the visual recognition module replaces the human eye, achieving far greater accuracy than the human eye can detect when identifying fine particles. If the miscibility of the bottled electrolyte to be tested does not meet the requirements (i.e., the miscibility identification is NG), the bottled electrolyte to be tested is clamped to the electrolyte NG sample rack, and subsequent pipetting and characterization tests are not performed; if the miscibility of the bottled electrolyte to be tested meets the requirements, the six-axis manipulator clamps the bottled electrolyte to be tested to the centralized liquid dispensing module, and the six-axis manipulator clamps an empty reagent bottle from each reagent bottle rack (including: Raman reagent bottle rack, conductivity reagent bottle rack, saturated vapor pressure reagent bottle rack and viscosity reagent bottle rack) to the centralized liquid dispensing module, and then the centralized liquid dispensing module divides the electrolyte to be tested in the bottled electrolyte to be tested into the above-mentioned reagent bottles of different specifications for characterization tests of different projects. Then, the six-axis manipulator clamps the bottled electrolyte to be tested after pipetting and separation (i.e., the remaining bottled electrolyte to be tested) to the aluminum foil packaging module, and then the aluminum foil packaging module packages the bottled electrolyte to be tested after pipetting and separation for recycling.

[0038] When the centralized liquid dispensing module is pipetting and dispensing liquids, a three-axis XYZ servo module is used to replace manual movement, and an automatic pipette pump replaces the manual pipette gun. Through program control, the purpose of accurately extracting and releasing the electrolyte to be tested is achieved. The servo rotating electric claw replaces human fingers to realize the opening and closing operations of each reagent bottle. In this way, the entire centralized liquid dispensing module realizes mechanical automation to replace manual pipetting and dispensing operations of the electrolyte to be tested.

[0039] After liquid separation is complete, a six-axis robot grips the reagent bottles, and a seventh-axis linear motor module replaces the human legs to move each reagent bottle to the corresponding characterization test module for the corresponding characterization test. The six-axis robot is fixed to the seventh-axis linear motor module. This combination replaces human hands and feet to achieve the grasping and movement of various materials. This electrolyte automatic testing workstation can perform the following four characterization tests: Raman test, conductivity test, saturated vapor pressure test, and viscosity test. After the test is completed, the seventh-axis linear motor module moves the six-axis robot to classify and recycle the reagent bottles. That is, each reagent bottle is clamped back to the corresponding position of the reagent bottle rack (i.e., the location where the reagent bottle was originally stored) for storage.

[0040] A new bottle of electrolyte to be tested is then grabbed from the electrolyte reagent bottle rack and subjected to characterization testing, marking a new round of electrolyte separation characterization testing. After all electrolyte tests are completed, the seventh-axis linear motor module moves the six-axis robotic arm to collect all discarded reagent bottles (i.e., used reagent bottles) and discarded test consumables (i.e., used pipette tips) from each reagent bottle rack. These are then stacked onto the material stacking tray and discharged through the material transfer bin on the other side, completing the process.

[0041] The electrolyte characterization test workstation of the present invention utilizes automated design to achieve unmanned testing operations and precise control of the test process, significantly improving test efficiency and freeing up manual labor to focus on test data analysis. The workstation autonomously completes repeated tests according to settings, collects standardized test data, and achieves high-throughput, standardized full-data chain management. Based on the collected test data, a corresponding mathematical model is constructed to explore the correlations therein. Based on the collected test library, the workstation relies on intelligent algorithms, artificial intelligence, and data-driven decision-making, providing optimization and solution design guidance for electrolyte research and development.

[0043] In an optional embodiment of the present invention, the electrolyte characterization test system further comprises: a movable material preparation rack; The movable material preparation rack is used to carry the manually prepared reagent bottles and test consumables before the electrolyte test, and transport them to the material transition warehouse. It can be moved away after loading is completed.
