Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to an electrolyte preparation device and an electrolyte preparation system. Background Technology

[0002] In related technologies, battery cells include electrolytes. Currently, the weighing accuracy of powder and liquid materials is low when preparing electrolytes, which affects the preparation accuracy of the electrolyte and thus the performance of the battery cells.

[0003] Therefore, there is an urgent need in the field for a device capable of configuring high-precision electrolytes. Utility Model Content

[0004] In view of the above problems, this application provides an electrolyte preparation device and an electrolyte preparation system, which aim to improve the preparation accuracy of electrolyte.

[0005] This application provides an electrolyte preparation device, which includes a base and a worktable. A preparation body is disposed on the base. A weighing mechanism is disposed on the worktable. The worktable and the weighing mechanism are spaced apart from the base and the preparation body. The weighing mechanism is used for placing and weighing a sample container. The preparation body is used for injecting powder and / or liquid into the sample container on the weighing mechanism.

[0006] In the technical solution of this application embodiment, a configuration body is provided on the base, and a weighing mechanism is provided on the worktable. The worktable and the weighing mechanism are spaced apart from the base and the configuration body, that is, the worktable and the base are independent of each other and spaced apart. The worktable can be independently placed on the ground relative to the base. This ensures that the vibration caused by the mechanical movement of the configuration body on the base during operation will not be transmitted to the worktable and affect the weighing mechanism, thus avoiding interference from the configuration body to the weighing mechanism on the worktable. In other words, the vibration generated by the operation of the configuration body on the base will not affect the accuracy of the weighing mechanism in weighing the powder and / or liquid in the sample container. This improves the stability of the weighing mechanism and thus improves the accuracy of preparing electrolyte from the powder and / or liquid weighed by the weighing mechanism.

[0007] In some embodiments, the base is provided with a receiving space, and the worktable is disposed in the receiving space. In this embodiment, by providing a receiving space on the base, the structure of the worktable and the base is compact, and the space utilization of the base is high. This not only facilitates the installation of the worktable and the weighing mechanism on the worktable, but also facilitates the main body to inject powder and / or liquid into the sample container on the weighing mechanism.

[0008] In some embodiments, the base includes a frame and a substrate. The frame has a receiving cavity for placing the worktable. The substrate is disposed on the frame and has a through hole exposing the worktable. The through hole communicates with the receiving cavity to form the receiving space. The weighing mechanism is installed on the worktable through the through hole. In this embodiment, the through hole exposes the worktable, facilitating the installation of the weighing mechanism onto the worktable. During assembly, the distance between the worktable and the weighing mechanism and the base is easily observed through the through hole, thus ensuring that the worktable and the weighing mechanism are spaced apart from the base and the main body. This improves the ease of assembly and the accuracy of the weighing mechanism in weighing powders and / or liquids in the sample container.

[0009] In some embodiments, the worktable is located below the substrate and spaced apart from the substrate; alternatively, a portion of the worktable is disposed within the through hole and spaced apart from the hole wall. This arrangement ensures that the worktable and the base are spaced apart, preventing vibrations generated by the operation of the main body on the base from being transmitted to the weighing mechanism and affecting the weighing accuracy, thus improving the stability of the weighing mechanism.

[0010] In some embodiments, the electrolyte preparation device further includes a displacement mechanism, which is disposed on the worktable and spaced apart from both the base and the preparation body. The weighing mechanism is disposed on the displacement mechanism, and the displacement mechanism is used to move the weighing mechanism on the worktable along the horizontal and / or vertical directions. In this embodiment, by moving the weighing mechanism on the worktable, the weighing mechanism can be moved closer to other mechanisms, thus reducing the travel distance of other mechanisms transferring sample containers on the weighing mechanism. This facilitates the transfer of sample containers containing electrolyte on the weighing mechanism, improves space utilization on the base, reduces the risk of collisions with other mechanisms on the base, and ultimately improves the electrolyte preparation efficiency.

[0011] In some embodiments, the weighing mechanism includes a balance and a limiting seat. The balance is mounted on the displacement mechanism, and the limiting seat is mounted on the balance. The limiting seat has a limiting groove for placing a sample container. In this embodiment, by setting a limiting seat on the balance with a limiting groove, the sample container can be stably installed on the balance, thus fixing the sample container and completely installing it within the limiting groove. The limiting seat also has a windproof function, preventing powder from being spilled and contaminated by airflow during powder injection, thereby improving the stability of the electrolyte preparation device.

[0012] In some embodiments, the configuration body includes a material injection mechanism, a container storage mechanism, and a transfer mechanism. The material injection mechanism, the container storage mechanism, and the transfer mechanism are disposed on the base and spaced apart from the workbench and the weighing mechanism. The container storage mechanism is used to store sample containers. The transfer mechanism is used to transfer sample containers between the container storage mechanism and the weighing mechanism. The material injection mechanism is used to inject powder and / or liquid into the sample containers on the weighing mechanism. In this embodiment, by setting a material injection mechanism, a container storage mechanism, and a transfer mechanism on the base, it is possible to automatically transfer the sample container to the weighing mechanism and automatically inject powder and / or liquid into the sample container on the weighing mechanism, thereby achieving automated electrolyte preparation, that is, automated electrolyte preparation. Furthermore, the material injection mechanism, container storage mechanism, and transfer mechanism on the base are all spaced apart from the worktable and the weighing mechanism. The vibration caused by the mechanical movement of the material injection mechanism and the transfer mechanism during operation will not be transmitted to the worktable and affect the weighing mechanism. This ensures the accuracy of the weighing mechanism in weighing the powder and / or liquid in the sample container, thereby improving the accuracy of electrolyte preparation from the powder and / or liquid weighed by the weighing mechanism.

[0013] In some embodiments, the injection mechanism includes a powder injection module and a liquid injection module, which, along with the container storage mechanism and the transfer mechanism, surround the worktable. This arrangement enables automatic injection of powder and liquid into the sample container on the weighing mechanism, thereby achieving automated electrolyte preparation. Furthermore, the powder injection module and liquid injection module are spaced apart from the worktable and weighing mechanism, preventing vibrations caused by their mechanical movement from being transmitted to the worktable and affecting the weighing mechanism. This ensures the accuracy of the weighing mechanism in weighing the powder and liquid in the sample container, thus improving the precision of electrolyte preparation from the weighed powder and liquid. Simultaneously, the compact arrangement of the mechanisms on the base improves space utilization.

[0014] In some embodiments, the electrolyte preparation device further includes a shaking mechanism disposed on the base and spaced apart from the worktable and the weighing mechanism. The shaking mechanism is used to place a sample container and shake the electrolyte within it. The transfer mechanism is used to transfer the sample container between the weighing mechanism, the shaking mechanism, and the container storage mechanism. In this embodiment, the shaking mechanism accelerates the dissolution of the electrolyte in the sample container, improving the electrolyte preparation efficiency. Furthermore, the vibrations caused by the shaking mechanism during operation are not transmitted to the worktable and thus do not affect the electrolyte preparation in the sample container on the weighing mechanism, thereby improving the accuracy of the electrolyte preparation device.

[0015] In some embodiments, the electrolyte preparation device further includes a heating element disposed on the shaking mechanism and spaced apart from the worktable. The heating element is used to heat the electrolyte in the sample container on the shaking mechanism. In this embodiment, the heating element further accelerates the dissolution of the electrolyte in the sample container on the shaking mechanism, improving the electrolyte preparation efficiency. Furthermore, the heating element does not affect the preparation of the electrolyte in the sample container on the weighing mechanism, thus improving the accuracy of the electrolyte preparation device.

[0016] In some embodiments, the shaking mechanism, the transfer mechanism, the container storage mechanism, and the dispensing mechanism are arranged around the periphery of the worktable, and the shaking mechanism and the container storage mechanism are arranged around the periphery of the transfer mechanism. This arrangement results in a compact arrangement of mechanisms on the base, improving space utilization. Furthermore, the mechanisms on the base are spaced apart from the worktable and the weighing mechanism on the worktable, preventing vibrations caused by the mechanical movement of the mechanisms on the base from being transmitted to the worktable and affecting the weighing mechanism. This ensures the accuracy of the weighing mechanism in weighing powders and liquids in the sample container, thereby improving the precision of preparing the electrolyte from the powders and liquids weighed by the weighing mechanism.

[0017] This application also proposes an electrolyte preparation system, which includes an electrolyte preparation device.

[0042] Currently, judging from market trends, batteries are widely used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in power tools, drones, energy storage devices, and many other fields. As the applications of batteries continue to expand, the market demand is also constantly increasing.

[0043] In some embodiments, the battery can be a battery module, and when there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0044] In some embodiments, the battery can be a battery pack, which includes a housing and individual battery cells, with the individual battery cells or battery modules housed within the housing.

[0045] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.

[0046] In some embodiments, the battery can be an energy storage device. Energy storage devices include energy storage containers, energy storage cabinets, etc.

[0047] In some embodiments, the battery cell can be a rechargeable battery, which refers to a battery cell that can be recharged after discharge to activate the active materials and continue to be used. The battery cell can be, but is not limited to, lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid batteries, etc.

[0048] As an example, the battery cell can be a cylindrical battery cell, a prismatic battery cell, a pouch battery cell, or a battery cell of other shapes. Prismatic battery cells include prismatic battery cells, blade-shaped battery cells, and multi-prismatic batteries, such as hexagonal prismatic batteries. There are no particular limitations in the embodiments of this application.

[0049] A battery cell is the smallest unit that makes up a battery. Within a battery cell, the electrolyte is a crucial component, playing a vital role in connecting the positive and negative electrodes, conducting ions, and providing the necessary chemical environment. Electrolytes typically consist of a solvent and dissolved salts, such as lithium salts. The quality, composition, concentration, and stability of the electrolyte directly affect the battery's performance, safety, and lifespan.

[0050] Currently, the weighing accuracy of powder and liquid materials during electrolyte preparation is relatively low, affecting the precision of electrolyte preparation and consequently the performance of individual battery cells. In particular, existing electrolyte preparation devices place the powder injection mechanism, liquid injection mechanism, transfer mechanism, and weighing mechanism on the same base. Vibrations generated during powder injection, liquid injection, and sample container transfer are all transmitted to the weighing mechanism. These vibrations, transmitted through the base, interfere with the weighing mechanism, resulting in low accuracy in weighing powder and liquid materials, thus impacting the precision of electrolyte preparation.

[0051] Based on the above considerations, in order to solve the problem of low precision in electrolyte preparation by existing electrolyte preparation devices, this application proposes a new electrolyte preparation device. The weighing mechanism in this electrolyte preparation device has high stability and accuracy, resulting in high precision in the prepared electrolyte.

[0052] To facilitate a better understanding of this application, the following description is provided in conjunction with the appendix. Figures 1 to 5 The electrolyte preparation device 10 in the embodiments of this application will be described in detail.

[0053] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of an electrolyte preparation device 10 according to some embodiments of this application. The electrolyte preparation device 10 includes a base 100 and a worktable 300. A preparation body 200 is disposed on the base 100. A weighing mechanism 400 is disposed on the worktable 300. The worktable 300 and the weighing mechanism 400 are spaced apart from the base 100 and the preparation body 200. The weighing mechanism 400 is used for placing and weighing sample containers. The preparation body 200 is used for injecting powder and / or liquid into the sample containers on the weighing mechanism 400.

[0054] Electrolyte preparation device 10 is a device used for mixing and preparing electrolytes, widely used in battery manufacturing and experimental fields. Its main function is to mix various chemical components to prepare the required electrolyte according to specific ratios and concentration requirements.

[0055] The base 100 is a component for supporting and mounting the mechanism. The base 100 can be a housing or a platform. A configuration body 200 is provided on the base 100; that is, the configuration body 200 is mounted on the base 100 and is the main configuration component for configuring the electrolyte. In this embodiment, the configuration body 200 is used to inject powder and / or liquid into the sample container on the weighing mechanism 400.

[0056] The workbench 300 is a component used for work or operation, possessing stability and load-bearing capacity. A weighing mechanism 400 is installed on the workbench 300. The weighing mechanism 400 is a device used for accurately measuring the mass of objects. In this embodiment, the weighing mechanism 400 is used for placing and weighing sample containers.

[0057] It can be understood that the sample container on the weighing mechanism 400 can be placed and transferred by the configuration body 200, or by other mechanisms or manually, without limitation.

[0058] The worktable 300 and the base 100 are spaced apart, meaning that the worktable 300 and the base 100 are independently arranged. The base 100 and the worktable 300 can be placed on the ground independently and at intervals without interfering with each other, and vibrations on the base 100 will not be transmitted to the worktable 300. The position of the worktable 300 relative to the base 100 is not limited. For example, the worktable 300 can be located on the side of the base 100 and spaced apart from the base 100; or, the base 100 has a receiving space 101, and the worktable 300 is located within the receiving space 101 and spaced apart from the base 100.

[0059] The main body 200 is mounted on the base 100. The worktable 300 is spaced apart from both the base 100 and the main body 200, meaning that the worktable 300 and the main body 200 do not interfere with each other, and vibrations caused by the mechanical movement of the main body 200 during operation will not be transmitted to the worktable 300. Furthermore, the weighing mechanism 400 is mounted on the worktable 300, and is also spaced apart from both the base 100 and the main body 200, meaning that the weighing mechanism 400 and the main body 200 do not interfere with each other, and vibrations on the base 100 will not be transmitted to the weighing mechanism 400, thus affecting the accuracy of the weighing.

[0060] In the technical solution of this application embodiment, the workbench 300 and the base 100 are independent of each other and spaced apart. The workbench 300 can be independently placed on the ground relative to the base 100. This ensures that the vibration caused by the mechanical movement of the main body 200 on the base 100 during operation will not be transmitted to the workbench 300 and affect the weighing mechanism 400. This avoids interference from the main body 200 on the weighing mechanism 400 on the workbench 300. In other words, the vibration generated by the operation of the main body 200 on the base 100 will not affect the accuracy of the weighing mechanism 400 in weighing the powder and / or liquid in the sample container. This improves the stability of the weighing mechanism 400 and thus improves the accuracy of preparing electrolyte from the powder and / or liquid weighed by the weighing mechanism 400.

[0061] According to some embodiments of this application, optionally, please refer to... Figure 1 , Figure 2 and Figure 4 The base 100 is provided with a accommodating space 101, and the worktable 300 is located in the accommodating space 101.

[0062] The accommodating space 101 is a space or area used to accommodate or place components. The accommodating space 101 may be in the form of a hole or a groove, and the specific form is not limited here.

[0063] In one embodiment, all of the worktables 300 are located within the accommodating space 101. In another embodiment, a portion of the worktables 300 are located within the accommodating space 101, while another portion are located outside the accommodating space 101. It is sufficient that the worktables 300 and the base 100 are spaced apart.

[0064] In this embodiment, by providing an accommodating space 101 on the base 100, the structure of the workbench 300 and the base 100 is compact, and the space utilization rate of the base 100 is high. This not only facilitates the installation of the workbench 300 and the weighing mechanism 400 on the workbench 300, but also facilitates the main body 200 to inject powder and / or liquid into the sample container on the weighing mechanism 400.

[0065] According to some embodiments of this application, optionally, please refer to... Figures 3 to 5 The base 100 includes a base frame 110 and a base plate 120. The base frame 110 has a receiving cavity 111 for placing the worktable 300. The base plate 120 is disposed on the base frame 110 and has a through hole 121 for exposing the worktable 300. The through hole 121 communicates with the receiving cavity 111 to form a receiving space 101. The weighing mechanism 400 is installed on the worktable 300 through the through hole 121.

[0066] The base frame 110 serves as a support, housing, or load-bearing frame or structure. The base frame 110 has a housing cavity 111, within which the worktable 300 is disposed, facilitating its placement on the ground. The base plate 120 is disposed on the base frame 110, serving as a support and load-bearing component. The configuration body 200 may be disposed on the base plate 120 and / or the base frame 110. In this embodiment, the configuration body 200 is disposed on the base plate 120.

[0067] The substrate 120 is provided with a through hole 121. The shape of the through hole 121 is not limited; it can be square, circular, or other shapes, and can be set as needed. The through hole 121 can be located above the receiving cavity 111, and the through hole 121 communicates with the receiving cavity 111 to form a receiving space 101, so that the worktable 300 in the receiving cavity 111 can be seen through the through hole 121. The worktable 300 can be entirely disposed within the receiving cavity 111; or, a portion of the worktable 300 can be disposed within the receiving cavity 111, and another portion within the through hole 121; or, a portion of the worktable 300 can be disposed within the receiving cavity 111, a portion within the through hole 121, and a portion extending beyond the through hole 121 and outside the substrate 120.

[0068] In this embodiment, the through hole 121 is used to expose the worktable 300, thereby facilitating the installation of the weighing mechanism 400 onto the worktable 300 through the through hole 121. During assembly, the distance between the worktable 300 and the weighing mechanism 400 and the base 100 can be easily observed through the through hole 121, thereby ensuring that the worktable 300 and the weighing mechanism 400 are spaced apart from the base 100 and the main body 200. This improves the ease of assembly and the accuracy of the weighing mechanism 400 in weighing powder and / or liquid in the sample container.

[0069] According to some embodiments of this application, optionally, the worktable 300 is located below the substrate 120 and spaced apart from the substrate 120; or, a portion of the worktable 300 is disposed within the through hole 121 and spaced apart from the hole wall of the through hole 121.

[0070] The position of the worktable 300 relative to the substrate 120 is not limited. The worktable 300 can be located below the through hole 121 of the substrate 120. Of course, part of the worktable 300 can also be located inside the through hole 121, as long as the worktable 300 and the substrate 120 are spaced apart. The weighing mechanism 400 is located on the worktable 300. Part of the weighing mechanism 400 can be located inside the through hole 121 and spaced apart from the hole wall of the through hole 121; or, all of the weighing mechanisms 400 can be located outside the through hole 121 and spaced apart from the substrate 120.

[0071] In this embodiment, the workbench 300 and the base 100 are spaced apart, so that the vibration generated by the operation of the main body 200 on the base 100 will not be transmitted to the weighing mechanism 400 and affect the weighing accuracy, thus improving the stability of the weighing mechanism 400.

[0072] According to some embodiments of this application, optionally, please refer to... Figure 1 , Figure 3 and Figure 5 The electrolyte preparation device 10 also includes a displacement mechanism 500, which is disposed on the workbench 300 and spaced apart from the base 100 and the preparation body 200. A weighing mechanism 400 is disposed on the displacement mechanism 500, and the displacement mechanism 500 is used to drive the weighing mechanism 400 to move on the workbench 300 in the horizontal and / or vertical direction.

[0073] The displacement mechanism 500 is used to adjust the position of the weighing mechanism 400 on the worktable 300, so as to adjust the position of the sample container on the weighing mechanism 400, so that the weighing mechanism 400 can be closer to other mechanisms on the base 100. That is, by moving the weighing mechanism 400 and the sample container on it, the stroke of other mechanisms on the base 100 to transfer the sample container is shortened, thereby reducing the mechanical action of other mechanisms on the base 100.

[0074] The displacement mechanism 500 may include a drive motor, a transmission assembly, and a guide assembly. The drive motor drives the weighing mechanism 400 to move under the guidance of the guide assembly via the transmission assembly, thereby adjusting the position of the weighing mechanism 400 on the worktable 300. The transmission assembly may be a pulley assembly, a gear and rack assembly, or a lead screw assembly, etc., and is not limited here. The guide assembly may be a slide rail and slider assembly or a magnetic levitation guide rail, and is not limited here.

[0075] It is understandable that the horizontal direction can be a straight line, a curved line, or a combination of both. In other words, the shape of the trajectory of the displacement mechanism 500 driving the weighing mechanism 400 to move horizontally across the worktable 300 is not limited and can be set as needed.

[0076] In one embodiment, the displacement mechanism 500 is used to adjust the height of the weighing mechanism 400 on the worktable 300, thereby adjusting the position of the sample container on the weighing mechanism 400. This allows the sample container to move closer to or further away from the powder injection head and / or liquid injection head of the configuration body 200, reducing the occurrence of collisions between the configuration body 200 and the sample container on the weighing mechanism 400, and improving the stability of the electrolyte preparation device 10. Exemplarily, the displacement mechanism 500 is a linear module.

[0077] In this embodiment, the weighing mechanism 400 is moved on the worktable 300 by the displacement mechanism 500, so that the weighing mechanism 400 can move on the worktable 300 to be closer to other mechanisms. This reduces the travel distance of other mechanisms to transfer the sample container on the weighing mechanism 400, facilitates the transfer of the sample container with electrolyte on the weighing mechanism 400, improves the space utilization of the base 100, reduces the risk of collision with other mechanisms on the base 100, and thus improves the electrolyte preparation efficiency.

[0078] According to some embodiments of this application, optionally, please refer to... Figure 1 , Figure 3 and Figure 5 The weighing mechanism 400 includes a balance 410 and a limiting seat 420. The balance 410 is mounted on the displacement mechanism 500, and the limiting seat 420 is mounted on the balance 410. The limiting seat 420 is provided with a limiting groove 421 for placing a sample container.

[0079] The balance 410 is an instrument used for accurately measuring the mass or weight of an object. In this embodiment, the balance 410 is used to weigh a sample container. A limiting seat 420 is mounted on the balance 410, and the limiting seat 420 is provided with a limiting groove 421. The limiting groove 421 is used for placing the sample container and can limit the sample container to prevent it from shaking on the weighing mechanism 400, thus affecting the weighing accuracy. The number of limiting grooves 421 can be one, two, or more, and is not limited here.

[0080] In this embodiment, by setting a limiting seat 420 on the balance 410, and providing a limiting groove 421 on the limiting seat 420, the sample container can be stably installed on the balance 410, thus fixing the sample container and completely installing the sample container within the limiting groove 421. The limiting seat 420 also has a windproof function, preventing the powder from being affected by airflow during the powder injection process and causing spillage and pollution, thereby improving the stability of the electrolyte preparation device 10.

[0081] According to some embodiments of this application, optionally, please refer to... Figures 1 to 4 The main body 200 includes a dispensing mechanism 210, a container storage mechanism 220, and a transfer mechanism 230. These three mechanisms are mounted on the base 100 and spaced apart from the worktable 300 and the weighing mechanism 400. The container storage mechanism 220 stores sample containers. The transfer mechanism 230 transfers sample containers between the container storage mechanism 220 and the weighing mechanism 400. The dispensing mechanism 210 dispenses powder and / or liquid into the sample containers on the weighing mechanism 400.

[0082] The container storage mechanism 220 is a device for storing, sorting, or transferring sample containers. For example, the container storage mechanism 220 may include a container storage rack with multiple storage holes for storing sample containers.

[0083] The transfer mechanism 230 is a mechanical device for moving objects between different positions. In this embodiment, the transfer mechanism 230 is used to transfer sample containers between the container storage mechanism 220 and the weighing mechanism 400. Exemplarily, the transfer mechanism 230 includes transfer grippers and a transfer assembly for driving the transfer grippers to move.

[0084] The injection mechanism 210 is a device for injecting materials into a designated location.

The injection mechanism 210, the container storage mechanism 220, and the transfer mechanism 230 can be located on the same side of the workbench 300, or on different sides, or around the perimeter of the workbench 300. The specific location is not limited, as long as the injection mechanism 210, the container storage mechanism 220, and the transfer mechanism 230 are spaced apart from the workbench 300 and the weighing mechanism 400 on the workbench 300.

[0085] In this embodiment, by providing a material injection mechanism 210, a container storage mechanism 220, and a transfer mechanism 230 on the base 100, it is possible to automatically transfer sample containers to the weighing mechanism 400 and automatically inject powder and / or liquid into the sample containers on the weighing mechanism 400, thereby achieving automated electrolyte preparation, i.e., automated electrolyte preparation. Furthermore, the material injection mechanism 210, the container storage mechanism 220, and the transfer mechanism 230 on the base 100 are all spaced apart from the worktable 300 and the weighing mechanism 400. The vibration caused by the mechanical movement of the material injection mechanism 210 and the transfer mechanism 230 during operation will not be transmitted to the worktable 300 and affect the weighing mechanism 400. This ensures the accuracy of the weighing mechanism 400 in weighing the powder and / or liquid in the sample containers, thereby improving the accuracy of electrolyte preparation from the powder and / or liquid weighed by the weighing mechanism 400.

[0086] According to some embodiments of this application, optionally, the injection mechanism 210 includes a powder injection module 211 and a liquid injection module 212, and the powder injection module 211, the liquid injection module 212, the container storage mechanism 220 and the transfer mechanism 230 are arranged around the workbench 300.

[0087] The powder injection module 211 is a device for injecting powdered materials into a designated location. In this embodiment, the powder injection module 211 is used to inject powder into the sample container on the weighing mechanism 400.

[0088] In one embodiment, the powder injection module 211 includes a powder injection support, a powder container, and a powder injection assembly. The powder injection support is disposed on the base 100, and the powder container and the powder injection assembly are disposed on the powder injection support. The powder injection assembly is used to drive the powder container to dispense powder. The powder container is disposed above the weighing mechanism 400. The powder dispensed from the powder container falls into the sample container on the weighing mechanism 400, and the weighing mechanism 400 weighs the powder.

[0089] In one embodiment, the powder injection module 211 may further include a powder injection lifting mechanism, which is disposed on the powder injection bracket, and the powder injection component is disposed on the powder injection lifting mechanism. The powder injection lifting mechanism is used to drive the powder injection component to move up and down along the height direction of the powder injection bracket in order to adjust the position of the powder injection component.

[0090] The liquid injection module 212 is a device for injecting liquid materials into a designated location. In this embodiment, the liquid injection module 212 is used to inject liquid into the sample container on the weighing mechanism 400.

[0091] In one embodiment, the liquid injection module 212 includes a liquid injection support, a liquid tank, and a liquid injection assembly. The liquid injection support is disposed on the base 100, and the liquid tank and the liquid injection assembly are disposed on the liquid injection support. The liquid injection assembly is used to discharge the liquid in the liquid tank to the outside. The liquid injection assembly may include a liquid injection head, through which the liquid in the liquid tank is discharged to the outside. The liquid injection head may be disposed above the weighing mechanism 400, and the liquid coming out of the liquid injection head flows into the sample container on the weighing mechanism 400, whereby the weighing mechanism 400 weighs the liquid.

[0092] In one embodiment, the injection module 212 may further include an injection lifting mechanism, which is disposed on the injection support and the injection component is disposed on the injection lifting mechanism. The injection lifting mechanism is used to drive the injection component to move up and down along the height direction of the injection support to adjust the position of the injection component.

[0093] In this embodiment, by setting up the powder injection module 211 and the liquid injection module 212, powder and liquid can be automatically injected into the sample container on the weighing mechanism 400, thereby realizing automated electrolyte preparation. Furthermore, the powder injection module 211 and the liquid injection module 212 are spaced apart from the worktable 300 and the weighing mechanism 400, so the vibration caused by the mechanical movement of the powder injection module 211 and the liquid injection module 212 during operation will not be transmitted to the worktable 300 and affect the weighing mechanism 400. This ensures the accuracy of the weighing mechanism 400 in weighing the powder and liquid in the sample container, thereby improving the accuracy of electrolyte preparation of the powder and liquid weighed by the weighing mechanism 400. At the same time, the compact arrangement of the mechanism structure on the base 100 is conducive to improving the space utilization of the base 100.

[0094] According to some embodiments of this application, optionally, please refer to... Figures 1 to 3 The electrolyte preparation device 10 also includes a shaking mechanism 600, which is disposed on the base 100 and spaced apart from the worktable 300 and the weighing mechanism 400. The shaking mechanism 600 is used to place the sample container and shake the electrolyte in the sample container. The transfer mechanism 230 is used to transfer the sample container between the weighing mechanism 400, the shaking mechanism 600 and the container storage mechanism 220.

[0095] The mixing mechanism 600 is a device for uniformly mixing two or more substances. The mixing mechanism 600 can mix liquids and powders uniformly by shaking, vibrating, or rotating. In this embodiment, the mixing mechanism 600 is used to place a sample container and mix the electrolyte within the sample container.

[0096] In one embodiment, the shaking mechanism 600 includes a vibration component with a placement hole for placing a sample container. The vibration component can shake the liquid and powder materials using a preset periodic motion, which can be a physical, mechanical, or acoustic wave-like fluctuation. Of course, in other embodiments, the vibration component can also use a non-periodic motion to shake the liquid and powder materials, and the specific settings can be configured as needed.

[0097] In this embodiment, the shaking mechanism 600 accelerates the dissolution of the electrolyte in the sample container on it, improves the electrolyte preparation efficiency, and the vibration caused by the shaking mechanism 600 during operation will not be transmitted to the worktable 300 and affect the preparation of the electrolyte in the sample container on the weighing mechanism 400, thus improving the accuracy of electrolyte preparation by the electrolyte preparation device 10.

[0098] According to some embodiments of this application, optionally, the electrolyte preparation device 10 further includes a heating element, which is disposed on the shaking mechanism 600 and spaced apart from the worktable 300. The heating element is used to heat the electrolyte in the sample container on the shaking mechanism 600.

[0099] A heating element is a component that converts electrical energy or thermal energy into heat. In this embodiment, the heat generated by the heating element is transferred to the sample container on the shaking mechanism 600 to heat the electrolyte in the sample container. The heating element can generate heat using electromagnetic heating, resistance heating, or infrared heating, and the specific method can be configured as needed.

[0100] In this embodiment, the heating element further accelerates the dissolution of the electrolyte in the sample container on the shaking mechanism 600, improving the electrolyte preparation efficiency. Furthermore, the heating element does not affect the preparation of the electrolyte in the sample container on the weighing mechanism 400, thus improving the accuracy of the electrolyte preparation device 10 in preparing the electrolyte.

[0101] According to some embodiments of this application, optionally, the shaking mechanism 600, the transfer mechanism 230, the container storage mechanism 220 and the filling mechanism 210 are arranged around the periphery of the worktable 300, and the shaking mechanism 600 and the container storage mechanism 220 are arranged around the periphery of the transfer mechanism 230.

[0102] The mixing mechanism 600, the transfer mechanism 230, and the container storage mechanism 220 can be located on the same side of the worktable 300, or they can be located on different sides of the worktable 300. The dispensing mechanism 210 is larger in volume than the mixing mechanism 600, the container storage mechanism 220, and the transfer mechanism 230. The dispensing mechanism 210 can be located on different sides of the worktable 300 from the transfer mechanism 230, thus making the arrangement of mechanisms on the base 100 more compact. The mixing mechanism 600 and the container storage mechanism 220 can be located on different sides of the transfer mechanism 230. For example, the mixing mechanism 600 and the container storage mechanism 220 are located on opposite sides of the transfer mechanism 230.

[0103] The technical solution of this embodiment makes the mechanism on the base 100 compact, which is conducive to improving the space utilization of the base 100. Moreover, the mechanisms on the base 100 are all spaced apart from the worktable 300 and the weighing mechanism 400 on the worktable 300, so that the vibration caused by the mechanical movement of the mechanisms on the base 100 during operation will not be transmitted to the worktable 300 and affect the weighing mechanism 400. This ensures the accuracy of the weighing mechanism 400 in weighing the powder and liquid in the sample container, thereby improving the accuracy of the preparation of electrolyte by the powder and liquid weighed by the weighing mechanism 400.

The weighing mechanism 400 includes a balance 410 and a limiting seat 420. The balance 410 is mounted on the displacement mechanism 500, and the limiting seat 420 is mounted on the balance 410. The limiting seat 420 has a limiting groove 421 for placing sample containers. The configuration body 200 includes a dispensing mechanism 210, a container storage mechanism 220, and a transfer mechanism 230. The dispensing mechanism 210, the container storage mechanism 220, and the transfer mechanism 230 are mounted on the base 100 and spaced apart from the worktable 300 and the weighing mechanism 400. The container storage mechanism 220 is used to store sample containers. The transfer mechanism 230 is used to transfer sample containers between the container storage mechanism 220 and the weighing mechanism 400. The dispensing mechanism 210 is used to dispense powder and liquid into the sample containers on the weighing mechanism 400. The filling mechanism 210 includes a powder filling module 211 and a liquid filling module 212, which are arranged around the worktable 300. The electrolyte preparation device 10 also includes a shaking mechanism 600, which is disposed on the base 100 and spaced apart from the worktable 300 and the weighing mechanism 400. The shaking mechanism 600 is used to place the sample container and shake the electrolyte in the sample container. The transfer mechanism 230 is used to transfer the sample container between the weighing mechanism 400, the shaking mechanism 600 and the container storage mechanism 220. The electrolyte preparation device 10 also includes a heating element, which is disposed on the shaking mechanism 600 and spaced apart from the worktable 300. The heating element is used to heat the electrolyte in the sample container on the shaking mechanism 600.The shaking mechanism 600, the transfer mechanism 230, the container storage mechanism 220 and the injection mechanism 210 are arranged around the worktable 300, and the shaking mechanism 600 and the container storage mechanism 220 are arranged around the transfer mechanism 230.

[0105] According to some embodiments of this application, the electrolyte preparation device 10 prepares the electrolyte as follows:

[0106] The transfer mechanism 230 transfers the sample container on the container storage mechanism 220 to the weighing mechanism 400.

[0107] The displacement mechanism 500 drives the weighing mechanism 400 to move below the powder injection module 211. The powder injection head of the powder injection module 211 injects a preset mass of lithium salt into the sample container. The weighing mechanism 400 records the data and feeds it back to the controller. The powder injection stops when the powder reaches the preset mass.

[0108] Among them, the lithium salt can be LiFSI (Lithium bis(fluorosulfonyl)imide), lithium bis(fluorosulfonyl)imide.

[0109] The displacement mechanism 500 drives the weighing mechanism 400 to move below the liquid injection module 212. The liquid injection head of the liquid injection module 212 injects a preset mass of solvent into the sample container. The weighing mechanism 400 records the data and feeds it back to the controller. The liquid injection stops after the solvent reaches the preset mass.

[0110] The solvent can be DME (Dimethyl Ether).

[0111] And / or, the solvent may be DOL (Dioxolane).

[0112] The displacement mechanism 500 drives the weighing mechanism 400 to move to the side of the shaking mechanism 600. The transfer mechanism 230 transfers the sample container containing lithium salt and solvent from the weighing mechanism 400 to the shaking mechanism 600. The shaking mechanism 600 shakes the sample container using a preset oscillation frequency and a preset time. The heating element heats the electrolyte in the sample container for a preset time. After the preset time, the prepared electrolyte can be obtained.

[0113] The transfer mechanism 230 transfers the sample container containing the prepared electrolyte from the shaking mechanism 600 to the storage area of ​​the container storage mechanism 220, thus completing the preparation of one bottle of electrolyte.

[0114] Repeat the above steps to prepare the required electrolyte.

[0115] Therefore, the electrolyte preparation system of this application can achieve automated electrolyte preparation, and the vibration generated by the operation of the mechanism on the base 100 will not affect the accuracy of the weighing mechanism 400 in weighing the powder and liquid in the sample container. The weighing mechanism 400 has high stability, thereby improving the accuracy of electrolyte preparation from the powder and liquid weighed by the weighing mechanism 400. At the same time, the displacement mechanism 500 drives the weighing mechanism 400 to move on the worktable 300, allowing the weighing mechanism 400 to move on the worktable 300 to be close to other mechanisms on the base 100. This reduces the travel distance of other mechanisms on the base 100 to transfer the sample container on the weighing mechanism 400, facilitates the transfer of the sample container containing electrolyte on the weighing mechanism 400, improves the space utilization of the base 100, reduces the risk of collision with other mechanisms on the base 100, and thus improves the electrolyte preparation efficiency.
