[0002] Sodium-ion batteries are a type of rechargeable battery that primarily relies on the movement of sodium ions between the positive and negative electrodes to function. Similar to lithium-ion batteries, during charging and discharging, Na+ ions move back and forth between the two electrodes, inserting and de-inserting: during charging, Na+ ions are de-inserted from the positive electrode and inserted into the negative electrode via the electrolyte; the reverse occurs during discharging. Currently, the preparation process for aqueous sodium-ion batteries requires mixing and stirring the prepared positive electrode active material with conductive agents, binders, and solvents to form a slurry, coating the slurry onto the surface of the current collector, drying, and rolling to obtain the positive electrode sheet.

[0003] In the process of preparing slurry, it is necessary to mix a variety of auxiliary materials. The traditional method is to directly add the various auxiliary materials into the shell and stir them together with the main material. This can easily lead to local concentration differences in the auxiliary materials, affecting the uniformity of mixing between the various auxiliary materials and the main material. Moreover, it is impossible to control the feeding during the addition process. Therefore, a doping device for sodium-ion batteries is proposed. Utility Model Content

A feeding hole 22 is opened on the top of the top placement plate 5. During the preparation process, the required auxiliary materials are placed in different adding tanks 11. The amount placed can be determined by observing the feeding scale 13 on one side.

[0017] Specifically, the stirring assembly includes a stirring motor 2 fixedly installed at the bottom of the mixing tank 1. The output end of the stirring motor 2 is connected to a stirring shaft 3, and multiple stirring blades 4 are fixedly installed on the stirring shaft 3. During the preparation process, the stirring motor 2 drives the stirring shaft 3 to rotate, which in turn drives the multiple stirring blades 4 to rotate, thus mixing and stirring the slurry.

[0018] Specifically, the telescopic moving assembly includes a set of fixed plates 6 fixedly installed on the top placement plate 5, a set of guide columns 7 fixedly installed between the set of fixed plates 6, a set of guide blocks 9 fixedly installed at the bottom of the moving plate 8, and a set of guide blocks 9 slidably installed on the set of guide columns 7. A telescopic cylinder 10 is fixedly installed on one side of the fixed plate 6, and the output end of the telescopic cylinder 10 is fixedly connected to one side of the moving plate 8. When it is necessary to add auxiliary materials, the telescopic cylinder 10 is started to drive the moving plate 8 to move. The operation of the telescopic cylinder 10 is controlled by an external control device. When the control device is running, the piston on the telescopic cylinder 10 will run, which can drive the moving plate 8 to move. The guide blocks 9 on the moving plate 8 can slide on the guide columns 7 to achieve movement limit. At this time, the multiple addition buckets 11 above move synchronously.

[0019] Specifically, the compression sealing assembly includes a sliding block 16 fixedly installed at the bottom of the sealing baffle plate 14, a sliding groove 15 opened at the top of the moving plate 8, the sliding block 16 slidably installed in the sliding groove 15, an end block 17 fixedly installed on one side of the moving plate 8, and a compression spring 18 fixedly installed between the end block 17 and the sliding block 16.

Under the pushing force of the compression spring 18, the sliding block 16 is located on one side of the sliding groove 15. The sealing baffle 14 will block the feeding pipe 12, and the auxiliary material will not fall. As it moves continuously, the adjusting roller 21 on the sealing baffle 14 will contact and squeeze the arc-shaped pushing block 20.

[0021] In use: During the process of mixing and stirring the prepared positive electrode active material, conductive agent, binder, and solvent to prepare the slurry, the auxiliary materials to be added are placed in different addition tanks 11. During the preparation process, the stirring motor 2 drives multiple stirring blades 4 to rotate and mix the slurry. When auxiliary materials need to be added, the telescopic cylinder 10 is activated to drive the moving plate 8 to move. The multiple addition tanks 11 above move synchronously. As they move, the adjusting roller 21 on the sealing baffle plate 14 will contact and squeeze the arc-shaped push block 20. At this time, the sliding block 16 moves and compresses the squeezing spring 18, and the sealing baffle plate 14 will be opened. At this time, the auxiliary materials in the corresponding addition tank 11 will automatically fall, realizing the automatic addition of materials. After the moving plate 8 moves, the auxiliary materials can be automatically added and discharged. Auxiliary materials can be added according to needs, avoiding the traditional method of dumping all auxiliary materials at once. It is more intelligent, precise, and convenient to use.
