Description

Technical Field

[0001] This utility model relates to the field of latex production technology, and in particular to an emulsification device for lithium battery latex binders. Background Technology

[0002] In recent years, the pursuit of high-energy-density lithium-ion batteries has never ceased, and there is an increasing need for high-energy, high-safety, long-cycle, and low-cost lithium-ion batteries to improve their application scope and effectiveness in power supplies and energy storage batteries. Currently, research and development on the main positive and negative electrode materials and various auxiliary materials for lithium-ion batteries has reached unprecedented levels. However, in next-generation lithium battery systems, high-specific-capacity positive and negative electrode materials remain a key factor in improving the energy density of lithium-ion batteries.

[0003] Given the abundance of silicon in the Earth's crust and its extremely high theoretical specific capacity (4200 mAh / g), it has become a research hotspot for next-generation high-energy-density lithium-ion battery anode materials in recent years. However, during charge-discharge cycles, silicon anode materials undergo tremendous volume expansion, reaching 300%, which leads to electrode pulverization and detachment, resulting in rapid capacity decay and increased safety risks, severely restricting the development of silicon anode materials.

[0004] To address the aforementioned issues, binders, which play a crucial role in the negative electrode material system, have attracted considerable attention. Negative electrode binders, using relatively small amounts, bond the entire negative electrode system materials and current collector together, enhancing the contact between active materials, conductive agents, and current collectors, and stabilizing the electrode structure. Before use, the binder needs to be emulsified to ensure uniform mixing with other raw materials and to maximize its bonding effect. Based on this, this application proposes a lithium battery latex binder emulsification device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a lithium battery latex binder emulsification device.

[0006] The purpose of this utility model is achieved through the following technical solution: a lithium battery latex binder emulsification device, including an emulsification tank, a plurality of uniformly arrayed feed pipes arranged in a ring shape installed below the tank wall of the emulsification tank, a plurality of circumferentially arrayed mounting holes opened on the inner side of the plurality of feed pipes, and a one-way valve installed inside each of the feed pipes, a stirrer rotatably installed inside the emulsification tank, a drain valve installed at the bottom of the emulsification tank, and a plurality of circumferentially arrayed heating rods installed at the top inside the emulsification tank, close to the tank wall.

[0007] Optionally, an annular tube is installed above the emulsification tank wall, with multiple circumferential array assembly holes on its inner side, and multiple heating rods are respectively installed in the multiple assembly holes.

[0008] Optionally, two valves are installed on the outer side of each of the multiple feed pipes.

[0009] Optionally, a lid for sealing is installed on top of the emulsifying tank.

[0010] Optionally, a motor is installed at the center of the top surface of the tank lid, and a stirring shaft is installed at its output end. Multiple uniformly arrayed stirring rods are installed on the outside of the stirring shaft, and the two are perpendicular to each other. A dispersing plate is rotatably installed at the outer end of each of the stirring rods.

[0011] This utility model has the following advantages:

[0012] This lithium battery latex binder emulsification device uses an emulsification tank as the main body. Two annular feed pipes are installed on the tank wall, and multiple one-way valves in a circular array are installed inside the tank to facilitate the uniform addition of emulsifier or raw materials into the emulsification tank by the operator, thereby improving the emulsification and dispersion effect. Inside the emulsification tank, a stirrer driven by a motor is installed, and multiple dispersion plates arranged perpendicular to it are installed on the outside. The raw materials can be dispersed in multiple directions by the rotation of the stirrer and the rotation of the dispersion plates.

[0013] Meanwhile, a ring pipe is installed above the emulsifying tank wall, with multiple vertically downward heating rods installed inside. Wiring can be arranged inside the ring pipe to ensure that the temperature of the heating rods can be raised, thereby changing the temperature of the emulsion in the emulsifying tank and improving the dispersion effect. The emulsified liquid can be discharged from the drain valve at the bottom of the emulsifying tank for easy use. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0021] like Figures 1 to 5 As shown, a lithium battery latex binder emulsification device includes an emulsification tank 1. Multiple uniformly arrayed feed pipes 11 are installed below the tank wall of the emulsification tank 1. The feed pipes 11 are annular. Multiple circumferentially arrayed mounting holes 13 are opened on the inner side of the multiple feed pipes 11. One-way valves 9 are installed inside each of the holes. An agitator is rotatably installed inside the emulsification tank 1. A drain valve 5 is installed at the bottom of the emulsification tank 1. Multiple circumferentially arrayed heating rods 8 are installed at the top inside the emulsification tank 1, close to the tank wall.

[0022] As an optional technical solution of this utility model, an annular tube 10 is installed on the upper part of the emulsifying tank 1, and multiple circumferential array assembly holes 12 are opened on its inner side. Multiple heating rods 8 are respectively installed in multiple assembly holes 12, which makes it convenient for workers to install the heating rods 8 and to arrange the cables connected to them.

[0023] As an optional technical solution of this utility model, two valves 3 are respectively installed on the outer side of the multiple feed pipes 11, which facilitates the circulation of material in and out of the feed pipes 11 and allows material to be fed from multiple directions of the tank.

[0024] As an optional technical solution of this utility model, a lid 2 for sealing is installed on the top of the emulsifying tank 1.

[0025] As an optional technical solution of this utility model, a motor 4 is installed in the middle of the top surface of the can lid 2, and a stirring shaft 6 is installed at its output end. Multiple uniformly arrayed stirring rods 14 are installed on the outside of the stirring shaft 6, and the two are perpendicular. Dispersion plates 7 are rotatably installed on the outer ends of the multiple stirring rods 14. This can improve the dispersion effect of the stirrer on the material. When the stirring shaft 6 rotates, the dispersion plates 7 will rotate irregularly to beat or impact the material, thereby dispersing and emulsifying the material.

[0026] In summary, the features, assembly method, usage process, and functions of each component in this utility model are as follows: Using an emulsifying tank 1 as the main body of the device, two annular feed pipes 11 are installed on the tank wall of the emulsifying tank 1. Multiple one-way valves 9 arranged in a circular array are installed inside the tank, facilitating the uniform addition of emulsifiers or raw materials to the emulsifying tank 1 by operators, thereby improving the emulsification and dispersion effect. An agitator driven by a motor 4 is installed inside the emulsifying tank 1, and multiple dispersion plates 7 arranged perpendicularly to it are installed on its outer side. The rotation of the agitator and the dispersion plates 7 can disperse the raw materials in multiple directions. A ring pipe 10 is installed above the tank wall of the emulsifying tank 1, with multiple vertically downward heating rods 8 installed inside. Wiring can be arranged within the ring pipe 10 to ensure that the temperature of the heating rods 8 can rise, thereby changing the temperature of the emulsion in the emulsifying tank 1 and improving the dispersion effect. The emulsified liquid can be discharged from the drain valve 5 at the bottom of the emulsifying tank 1 for easy use.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
