[0051] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a high-throughput preparation device for synthesizing electrode material precursors based on a solution method, including: a first pipetting component 100, a second pipetting component 200, a flow distribution component 300 and a heating and shaking platform 400; the first pipetting component 100 extends along a first direction, the second pipetting component 200 extends along a second direction, the second pipetting component 200 is slidably connected to the first pipetting component 100, and the first direction and the second direction are vertically arranged; the heating and shaking platform 400 is arranged below the second pipetting component 200, and a plurality of sample slots 410 arranged in an array are arranged on the heating and shaking platform 400; the flow distribution component 300 is slidably connected to the second pipetting component 200, and the flow distribution component 300 includes a liquid storage component 310 and a nozzle 320, the nozzle 320 is connected to the liquid storage component 310, the liquid storage component 310 is used to store a variety of solutions, and the solution in the liquid storage component 310 can enter the sample slot 410 through the nozzle 320.

The entire preparation process is simple and a large number of experimental results can be obtained in one operation, which greatly shortens the development cycle and R&D cost of electrode materials.

[0053] Regarding the shape and structure of the first pipetting component 100, in detail:

[0054] like Figure 1 As shown, the first moving component includes a first lead screw 110 and a first slide rail 120, both of which extend along the first direction, and the first slide rail 120 is arranged below the first lead screw 110 and parallel to the first lead screw 110; the second pipetting component 200 includes a first connecting member 210, which is threadedly connected to the first lead screw 110 and slidably connected to the first slide rail 120; the first lead screw 110 can rotate around its own axis to drive the first connecting member 210 to move along the first direction.

[0055] Specifically, the first connecting member 210 is sleeved on the first lead screw 110 and is threadedly connected to the first lead screw 110. The bottom of the first connecting member 210 extends into the first slide rail 120 and is slidably connected to the first slide rail 120. The first slide rail 120 plays a role of limiting and guiding. When the first lead screw 110 rotates around its own axis, due to the limitation of the first slide rail 120, the first connecting member 210 can move along the length direction (i.e., the first direction) of the first lead screw 110. The first connecting member 210 can be specifically configured as a slider, and the slider has a through hole, and the inner wall of the through hole is provided with a thread. The slider is sleeved on the first lead screw 110, and the internal thread of the slider matches the external thread of the first lead screw 110. The slider is threadedly connected to the first lead screw 110. Since the structure of the slider is an existing structure, it is not repeated here.

[0056] In an optional embodiment, in order to enable the first screw 110 to rotate, the first moving assembly is also provided with a first driving member 130. The first driving member 130 can be specifically configured as a stepping motor. The output end of the first driving member 130 is connected to the first screw 110, and the first driving member 130 drives the first screw 110 to rotate around its own axis.

[0057] In an optional embodiment, the first moving assembly is further provided with a first support base 140 , the first driving member 130 is connected to the first support base 140 , and the first support base 140 is connected below the first slide rail 120 .

[0058] Specifically, a plurality of first support bases 140 may be provided, the first driving member 130 may be fixedly connected to the first support base 140 near the first driving member 130 through a connecting plate, a support frame is provided on the first support base 140, one end of the first lead screw 110 passes through the support frame and is connected to the output shaft of the motor, and the end of the first lead screw 110 is rotatably connected to the support frame, and the other end of the first lead screw 110 is rotatably connected to a support frame provided on another first support base 140. Preferably, in order to make the first lead screw 110 rotate smoothly, the first lead screw 110 and the support frame may be connected through a bearing. The remaining first support bases 140 may be evenly distributed at the bottom of the first slide rail 120 to play a supporting role.

[0059] Regarding the shape and structure of the second pipetting component 200, in detail:

[0060] like Figure 1As shown, the second pipetting assembly 200 includes a second lead screw 220 and a second slide rail 230, both of which extend in the second direction, and the second slide rail 230 is arranged below the second lead screw 220, and the second slide rail 230 is arranged in parallel with the second lead screw 220; the second slide rail 230 is connected to the top of the first connecting member 210, and in order to make the movement of the second slide rail 230 more stable, the number of the first connecting members 210 is set to two, and the two first connecting members 210 are respectively connected to the bottom ends of the second slide rail 230, and correspondingly, the first pipetting assembly 100 is also provided with two groups, and the two groups of first pipetting assemblies 100 are arranged in parallel, and the two first connecting members 210 are respectively slidably connected with the two first lead screws 110. The flow distribution assembly 300 includes a second connecting member 330, which is threadedly connected to the second lead screw 220 and slidably connected to the second slide rail 230, and the second lead screw 220 can rotate around its own axis to drive the second connecting member 330 to move in the second direction.

[0061] Specifically, the second connecting member 330 is sleeved on the first lead screw 110 and is threadedly connected to the second lead screw 220. The bottom of the second connecting member 330 extends into the second slide rail 230 and is slidably connected to the second slide rail 230. The second slide rail 230 plays a role of limiting and guiding. When the second lead screw 220 rotates around its own axis, due to the limitation of the second slide rail 230, the second connecting member 330 can move along the length direction (i.e., the second direction) of the second lead screw 220. The second connecting member 330 can be specifically configured as a slider, the slider has a through hole, and the inner wall of the through hole is provided with a thread. The slider is sleeved on the second lead screw 220, the internal thread of the slider matches the external thread of the second lead screw 220, and the slider is threadedly connected to the second lead screw 220. Since the structure of the slider is an existing structure, it is not repeated here.

[0062] In an optional embodiment, in order to enable the second lead screw 220 to rotate, the second moving assembly is further provided with a second driving member 240. The second driving member 240 can be specifically configured as a stepping motor. The output end of the second driving member 240 is connected to the second lead screw 220. The second driving member 240 drives the second lead screw 220 to rotate around its own axis.

[0063] In an optional embodiment, the second moving assembly is further provided with a second support base 250 , the second driving member 240 is connected to the second support base 250 , and the second support base 250 is connected below the second slide rail 230 .

[0064] Specifically, the second support base 250 is connected to the bottom of the second slide rail 230 and to the top of the first connection member 210. The second support base 250 plays a role of supporting and strengthening stability. At least two second support bases 250 may be provided. The second driving member 240 may be fixedly connected to the second support base 250 near the second driving member 240 through a connecting plate. A support frame is provided on the second support base 250. One end of the second lead screw 220 passes through the support frame and is connected to the output shaft of the motor. One end of the second lead screw 220 is rotatably connected to the support frame, and the other end of the second lead screw 220 is rotatably connected to the support frame provided on another second support base 250. Preferably, in order to make the second lead screw 220 rotate smoothly, the second lead screw 220 and the support frame may be connected through a bearing.

[0065] Preferably, the traversal speeds of the first pipetting component 100 and the second pipetting component 200 can be divided into three speeds of high, medium and low speeds with an adjustment speed range of 0-3m / s, wherein the maximum speed does not exceed 3m / s because too high a speed will cause the stepper motor to slip and lose the transmission effect.

[0066] Regarding the shape and structure of the heating and shaking platform 400, in detail:

[0067] like Figure 3 As shown, the heating and shaking platform 400 is disposed below the second pipetting component 200 , and a plurality of sample slots 410 arranged in an array are disposed on the heating and shaking platform 400 .

[0068] Specifically, the two groups of first pipetting components 100 are symmetrically arranged on both sides of the heating and oscillating platform 400. The heating and oscillating platform 400 in this embodiment is a multi-channel heating and oscillating platform 400. The slot group of the multi-channel heating and oscillating platform 400 is arranged on the platform in a 7×7 array. A resistance wire heating base 420 is provided at the bottom of each sample slot 410. The resistance wire heating base 420 is a heating function realized by the resistance wire provided at the bottom of the sample slot 410.

[0069] In an optional embodiment, the heating oscillation platform 400 can achieve an oscillation frequency of 0-50 Hz, and the resistance wire heating base 420 can control the temperature of the solution medium in the sample tank 410 to be between 70-100°C.

[0070] In an optional embodiment, the capacity of the sample tank 410 may be set between 50-200 mL. The reason is that a capacity exceeding 200 mL may cause the solution to spill out of the sample tank 410 during the shaking process, while a capacity that is too low may result in insufficient mixing of the solution.

[0071] Regarding the shape and structure of the flow distribution component 300, in detail:

[0072] like Figure 2 As shown, the flow distribution component 300 in this embodiment is a multi-channel flow distribution component 300, and the flow distribution component 300 includes a liquid storage component 310 and a nozzle 320. The nozzle 320 is connected to the liquid storage component 310. The liquid storage component 310 is used to store a variety of solutions. The solution in the liquid storage component 310 can enter the sample tank 410 through the nozzle 320. A plurality of uniformly arranged liquid storage tubes 311 are provided in the liquid storage component 310.

[0073] In an optional embodiment, the flow distribution assembly 300 further includes a high-precision flow controller 340; the input end of the high-precision flow controller 340 is connected to the liquid storage component 310, and the output end is connected to the nozzle 320. The high-precision flow controller 340 is used to control the liquid inlet flow of different component solutions in the liquid storage tube 311. The high-precision flow controller 340 can independently control the flow of each channel.

[0074] Specifically, the liquid storage component 310 is a multi-channel liquid storage tank, which is composed of 8 independent liquid storage tubes 311. Through the high-precision flow controller 340, the liquid inlet flow rate of different component solutions in the liquid storage tube 311 can be independently controlled, and finally added to the sample tank 410 through the nozzle 320.

[0075] In an optional embodiment, in order to facilitate cleaning and replacement of the multi-channel liquid storage tank, it is connected to the flow controller via a detachable connector. The detachable connector 350 is arranged between the liquid storage component 310 and the high-precision flow controller 340, and the input end is connected to the liquid storage component 310, and the output end is connected to the high-precision flow controller 340.

[0076] In order to achieve automation and precise control, the present embodiment is also provided with a central control platform 500 and a sensor 600 for positioning. The central control platform 500 is electrically connected to the first pipetting component 100, the second pipetting component 200, the flow distribution component 300 and the heating and shaking platform 400; the sensor 600 is connected to the second pipetting component 200.

[0077] Specifically, the first pipetting component 100, the second pipetting component 200, the flow distribution component 300 and the heating and shaking platform 400 are all connected to the central control platform 500 through control lines. The first pipetting component 100 and the second pipetting component 200 control the motor and the screw rod through the preset program of the central control platform 500 to allow the connecting component to adjust the position of the flow distribution component 300, wherein the role of the sensor 600 is mainly to play a positioning role. With the cooperation of the first pipetting component 100 and the second pipetting component 200, the flow distribution component 300 can be controlled to traverse each sample slot 410 according to the preset program.

[0078] In view of the many problems existing in the traditional electrode material synthesis process, such as long experimental cycle, high cost, and complicated steps, this embodiment provides a high-throughput preparation device. The high-throughput preparation device utilizes a high-throughput, automated solution to automatically prepare electrode material precursors with various doping ratios. The entire preparation process is simple and a large number of experimental results can be obtained in one run, which greatly shortens the development cycle and R&D cost of electrode materials.
