Description

Technical Field

[0001] This invention belongs to the field of lithium-ion battery wetting technology, and in particular relates to a vibration-type wetting device for lithium-ion battery electrolyte. Background Technology

[0002] A lithium-ion battery is a rechargeable battery that uses lithium ions as its core charge carrier. It achieves charge-discharge cycles by the insertion and extraction of lithium ions between the positive and negative electrodes. It is currently the most widely used electrochemical energy storage device in consumer electronics, new energy vehicles, and energy storage systems. It mainly consists of a positive electrode, a negative electrode, a separator, an electrolyte, and a casing. During operation, lithium ions move between the two electrodes through the electrolyte, completing the conversion between electrical and chemical energy. Lithium-ion batteries have advantages such as high energy density, long cycle life, no memory effect, low self-discharge, and high operating voltage. They are a core component of modern high-performance energy storage and power systems, and the quality of the electrolyte wetting directly affects the battery's internal resistance, capacity, safety, and lifespan.

[0003] Currently, lithium-ion battery electrolyte impregnation mostly employs a static impregnation method, which suffers from slow impregnation speed, long cycle time, and low production efficiency. Furthermore, relying solely on the electrolyte's own fluidity for penetration makes it difficult to quickly and fully penetrate the tiny gaps between the electrodes and separator, easily leading to uneven impregnation and localized electrolyte shortages, directly impacting battery capacity, cycle life, and safety. To address these issues, we provide a vibration-type impregnation device for lithium-ion battery electrolytes to solve the aforementioned problems. Summary of the Invention

[0008] Furthermore, a heating element is provided inside the housing, the heating element including a spiral water pipe, with an inlet pipe and an outlet pipe extending to the outside of the housing connected sequentially at both ends of the spiral water pipe. The inlet pipe and the outlet pipe are both made of a retractable flexible hose.

[0009] Furthermore, an arc-shaped moving block is fixedly connected between the two top rods, and an annular plate is slidably fitted between the two arc-shaped moving blocks.

[0013] The present invention has the following beneficial effects: 1. The present invention can generate stable and uniform high-frequency vibration through the linkage structure of the eccentric wheel, the spiral plate, the swing plate and the connecting rod of the vibration component, which drives multiple lithium batteries to make regular reciprocating motion, effectively solving the problems of slow wetting speed and uneven electrolyte penetration in traditional static wetting. The first motor drives the eccentric wheel to rotate through belt transmission, and the power transmission is smooth. The lifting plate moves up and down in a directional manner along the guide sleeve, and the swing plate pushes and pulls to achieve multi-dimensional vibration, avoiding the blind zone of wetting in a single direction. The mounting base and the slide rail slide together, and the vibration transmission is more uniform, which can make the electrolyte quickly penetrate into the gap between the lithium battery electrode and the separator, significantly improving the wetting efficiency and fullness.

[0014] 2. This invention constructs a vibration-assisted heating immersion system by adding heating elements and receiving components. The spiral water pipe, through which circulating hot water is introduced, can precisely control the temperature inside the tank, effectively reducing the viscosity of the electrolyte and significantly accelerating the penetration speed of the electrolyte in the tiny gaps between the lithium battery electrodes and separators. This shortens the immersion cycle and improves the immersion sufficiency. The arc-shaped plate, arc-shaped toothed plate, and incomplete gear work together to drive the spiral water pipe to make reciprocating arc-shaped oscillations. With the help of the return spring, cyclical motion is achieved, which makes the heat in the tank evenly diffused, eliminating heating blind spots and avoiding local overheating that could damage the cell performance. At the same time, it ensures that the electrolyte is heated evenly and the immersion effect is consistent. The electric push rod can flexibly adjust the height of the heating element to adapt to different specifications of lithium batteries, greatly improving the versatility and adaptability of the device.

[0015] 3. This invention uses a PLC controller to uniformly control the first motor, the second motor, and the electric push rod, realizing fully automated operation of the entire process of cell heating and multi-dimensional vibration immersion without manual intervention, effectively reducing labor costs, avoiding human error, and significantly improving production efficiency. It is suitable for the needs of large-scale lithium battery production. The housing for receiving components is firmly fixed by the first support column, the sealing cover plate reduces heat loss, the rectangular pad provides stable support, and the guide groove and the horizontal plate ensure smooth lifting of the heating element. During vibration, the structure does not loosen or shift, and the operation is highly stable.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figure 1-6The present invention provides the following technical solution: a vibration-type impregnation device for lithium-ion battery electrolyte, comprising a vibration assembly 1; the vibration assembly 1 includes a base 101, a first upright plate 102 fixedly connected to the top of the base 101, a first rotating shaft 103 rotatably connected through one side of the first upright plate 102, an eccentric wheel 104 fixedly connected to one end of the first rotating shaft 103, a connecting plate 105 fixedly connected to one side of the first upright plate 102, a guide sleeve 106 fixedly connected to one side of the connecting plate 105, a lifting plate 107 slidably connected to the inner wall of the guide sleeve 106, a loop plate 108 slidably sleeved on the eccentric wheel 104 fixedly connected to the bottom of the lifting plate 107; a slide rail 109 fixedly connected to the top of the lifting plate 107, a mounting base 110 slidably connected to the slide rail 109, a first swing plate 111 hinged to one side of the mounting base 110, a second upright plate 112 fixedly connected to the top of the base 101, and one side of the second upright plate 112 rotating. The system includes a second swing plate 113, with a first connecting column 114 fixedly connected to one side of the second swing plate 113, which rotatably engages with the first swing plate 111. A support plate 115 is hinged to the second swing plate 113. A rotating plate 116 is rotatably connected to one side of the eccentric wheel 104, with a second connecting column 117 fixedly connected to one side of the rotating plate 116. The second connecting column 117 rotatably engages with the support plate 115. The vibration assembly 1 also includes a first motor 118 fixedly connected to the top of the base 101. A first pulley 119 is fixedly connected to the output end of the first motor 118. A second pulley 120 is fixedly connected to the other end of the first rotating shaft 103. A belt is used for transmission between the first pulley 119 and the second pulley 120. An arc-shaped seat adapted to the U-shaped plate 108 is symmetrically fixedly connected to the top of the base 101. Several first support columns 121 are symmetrically fixedly connected to the top of the mounting base 110. A control box 122 is fixedly connected to the top of the base 101.

[0021] The operation process of this embodiment is as follows: By controlling the start of the first motor 118, the first pulley 119, belt and second pulley 120 are smoothly driven to continuously rotate the first rotating shaft 103 and the eccentric wheel 104 through the transmission cooperation. During the rotation, the eccentric wheel 104 drives the outer sleeved spiral plate 108 to make regular up and down reciprocating motion, thereby driving the lifting plate 107 to rise and fall stably along the inner wall of the guide sleeve 106 to avoid swaying and deviation. At the same time, the eccentric wheel 104 synchronously drives the side rotating plate 1 16. The rotating plate 116 pulls the support plate 115 through the second connecting column 117. The support plate 115 then drives the second swing plate 113 to swing around the second vertical plate 112. The second swing plate 113 is transmitted to the first swing plate 111 through the first connecting column 114, and finally pushes the mounting base 110 to slide back and forth horizontally along the slide rail 109, so that the mounting base 110 has a composite motion form of vertical lifting and horizontal sliding at the same time, forming a multi-dimensional and highly uniform vibration effect. The base 101 is equipped with... The arc-shaped seat, referred to as the U-shaped plate 108, provides limiting support and motion guidance, reducing impact and friction loss. The first support column 121 at the top of the mounting base 110 is used to stabilize the positioning, heating and other functional components above, ensuring that the overall structure does not loosen or shift during vibration. The control box 122 on the base 101 realizes the start and stop, speed adjustment and operation sequence control of the first motor 118. This structure adopts a drive method that combines the transmission of the eccentric wheel 104 and the linkage of the multi-link swing plate, which transforms the single rotational power into a vertical and horizontal composite vibration form. The vibration trajectory is regular, the force is uniform, and the power transmission is continuous and smooth, which can significantly improve the penetration speed and filling uniformity of the lithium-ion battery electrolyte inside the cell, effectively shorten the immersion time and improve the immersion effect. At the same time, the cooperation design between the guide sleeve 106 and the arc-shaped seat greatly improves the motion stability, reduces mechanical impact and component wear, significantly extends the continuous working life and reliability of the device, and meets the stability requirements of continuous industrial production.

[0022] Example 2, please refer to Figure 1-6This second embodiment is an improvement on the first embodiment as follows: A receiving component 2 is fixedly fitted to the top of the vibration assembly 1. The receiving component 2 includes a housing 201. A sealing cover plate is hinged to the top of the housing 201, and a handle is fixedly connected to the top of the sealing cover plate. The housing 201 is fixedly connected to several first support columns 121. A rectangular pad 202 is fixedly connected to the bottom of the housing 201. Guide grooves 203 are provided on both opposite sides of the housing 201. A heating element 3 is provided inside the housing 201. The heating element 3 includes a spiral water pipe 301. Both ends of the spiral water pipe 301 are sequentially connected to a section extending to the outside of the housing 201. The inlet and outlet pipes are both made of flexible hose material. The outer wall of the spiral water pipe 301 is symmetrically fixed with an arc plate 302. The top of the arc plate 302 is symmetrically fixed with a top rod 303. An arc-shaped moving block 304 is fixedly connected between the two top rods 303. An annular plate 305 is slidably fitted between the two arc-shaped moving blocks 304. The bottom of the annular plate 305 is symmetrically provided with an arc-shaped groove 306 that slides with the two arc-shaped moving blocks 304. The outer wall of the annular plate 305 is symmetrically provided with a horizontal plate 307 that slides with the inner wall of the box 201. The horizontal plate 307 slides with the guide groove 203.

[0023] An arc-shaped toothed plate 308 is fixedly connected to the outer wall of one of the arc-shaped plates 302, and a baffle 309 is fixedly connected to the inner wall of the arc-shaped slide 306. A return spring 310 is fixedly connected between the baffle 309 and one of the arc-shaped moving blocks 304. The heating element 3 also includes an electric push rod 311 fixedly connected to the rectangular pad 202. A fixed plate 312 is fixedly connected to the output end of the electric push rod 311. The fixed plate 312 is fixedly connected to one of the horizontal plates 307. A second motor 313 is fixedly connected to the bottom of one of the fixed plates 312. A transmission rod 314 is fixedly connected to the output end of the second motor 313.

The PLC controller is electrically connected to the first motor 118, the second motor 313, and the electric push rod 311 through wires.

[0024] The operation process of this embodiment is as follows: In the receiving component 2, the box 201 is stably installed on the top of the vibration component 1 by the first support column 121. The top hinged sealing cover plate, together with the handle, facilitates the placement and removal of battery cells and reduces heat loss. The rectangular pad 202 at the bottom of the box provides stable support, and multiple battery packs are fixedly installed on the rectangular pad 202. The guide grooves 203 on both sides of the box 201 provide precise guidance for the lifting and lowering movement of the heating element 3, ensuring smooth and non-deviation-free movement. The heating element 3 serves as the temperature control core. The spiral water pipe 301 is connected to the inlet and outlet water pipes through an external retractable hose. After circulating hot water is introduced, the electrolyte in the box can be heated evenly, effectively reducing the viscosity of the electrolyte and accelerating the electrolyte to the lithium battery electrode. The micro-gap between the sheet and the diaphragm significantly improves the wetting rate and penetration depth.

The electric push rod 311 on the rectangular pad 202 drives the fixed plate 312 to move the horizontal plate 307 up and down along the guide groove 203. The height of the heating element 3 can be flexibly adjusted according to the size of the lithium battery to accurately match the heating requirements of different specifications of battery cells and improve the versatility of the device. The second motor 313 at the bottom of the fixed plate 312 drives the incomplete gear 315 to rotate via the transmission rod 314. The incomplete gear 315 meshes with the arc-shaped toothed plate 308 on the outer wall of the arc-shaped plate 302, driving the arc-shaped plate 302 and the spiral water pipe 301 to perform reciprocating arc-shaped oscillations. At the same time, the return spring 310 between the baffle 309 and the arc-shaped moving block 304 provides the return force, realizing the continuous cycle of oscillation, allowing the heat inside the box to be evenly distributed, avoiding local overheating that could damage the battery cell performance, while also eliminating heating blind spots, ensuring uniform heating of the electrolyte, and further improving performance. Improved wetting consistency; the PLC controller in the control box 122 is electrically connected to the first motor 118, the second motor 313, and the electric push rod 311, uniformly controlling the start-stop, speed, and action sequence of each component, realizing the fully automated operation of the entire process of cell feeding, positioning, heating, and multi-dimensional vibration wetting without manual intervention, reducing labor costs and avoiding human operation errors. It has a high degree of integration and automation, and precise and reliable temperature control, ultimately significantly improving the wetting efficiency, sufficiency, and finished product quality of lithium battery electrolyte, adapting to the needs of large-scale lithium battery production.
