Description

Technical Field

[0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery electrolyte solvent dissolving device. Background Art

[0002] Lithium battery is an important rechargeable battery, widely used in electric vehicles, mobile devices, energy storage systems and other fields. Lithium battery is essentially a battery with a concentration difference. The positive and negative electrode materials have different electrochemical potentials. The core of lithium battery is electrolyte. Electrolyte is known as the "blood" of lithium-ion battery and is one of the four key materials of lithium-ion battery. Therefore, ensuring the quality of electrolyte is also an important link for lithium battery to work effectively. Electrolyte plays the role of electron conduction and ion transmission. Electrolyte is usually composed of organic solvents, lithium salts and additives.

[0003] In the production process of lithium batteries, the preparation of electrolyte is a key link. One of the main processes of preparing electrolyte is to fully dissolve the solvent and lithium salt to form a stable electrolyte formula. This process requires the use of equipment to stir and heat the solvent and lithium salt to achieve the dissolution reaction. Traditional dissolution equipment still has many shortcomings during use or operation;

[0004] The specific defects are as follows:

[0005] ① Traditional dissolution equipment only stirs within a fixed range, which will form dead corners or areas that are difficult to stir inside the dissolution equipment, resulting in insufficient mixing uniformity of the solvent and lithium salt, and local concentration differences. Unevenly mixed solutions will affect the performance and stability of the battery. Uneven mixing will lead to uneven chemical reactions in the battery, which will have a negative impact on the battery's capacity, cycle life and safety. It will also lead to uneven distribution of lithium ions in the battery, resulting in unstable battery performance. Unstable battery performance will lead to reduced battery capacity, shortened cycle life and unstable power output.

[0006] ② The dissolution of lithium salt in solvent is a process involving intermolecular interaction and dissolution reaction. Traditional dissolution equipment is not good at controlling the reaction time of lithium salt, which will cause the lithium salt to fail to dissolve completely, resulting in a large number of undissolved particles or crystals in the solution, which will affect the uniform distribution of positive and negative electrode materials of the battery and reduce the performance and stability of the battery. The interaction and reaction between certain solvents and lithium salts is a slow process and requires a certain amount of time to reach equilibrium. Insufficient reaction time of lithium salt will lead to a very slow reaction rate between the solvent and lithium salt, resulting in the inability to fully proceed with the reaction, which will cause unreacted lithium salt in the battery, affecting the electrochemical reaction and the stability of battery performance.

[0007] Therefore, the present invention proposes a lithium battery electrolyte solvent dissolution device to improve the shortcomings of the traditional technology, so as to achieve full mixing of the solvent and the lithium salt and give the lithium salt sufficient reaction time.

[0043] The following is the entire working process and working principle of the above embodiment:

[0044] First, the operator pours the material solvent and lithium salt for preparing the electrolyte into the equipment housing 1 from the feed port. A heating plate is fixedly connected in the equipment housing 1. The operator turns on the heating plate to heat and dissolve the solvent and the lithium salt. The operator starts the motor. Since the first cylinder 41 is driven and installed on the motor, the motor drives the first cylinder 41 to rotate. When the first cylinder 41 rotates, it drives the first gear 42 to rotate. When the first gear 42 rotates, it drives the first baffle plate 43 to rotate. When the first gear 42 rotates, it drives the incomplete gear 45 meshing with it to rotate one circle. The number of teeth of the first gear 42 is one more than the number of teeth of the incomplete gear 45. Because the first gear 42 first drives the first baffle plate 43 to rotate and the number of teeth, the first gear 42 does not touch the second baffle plate 44 when it rotates the second circle. At this time, the first gear 42 and the incomplete gear 45 are not in a meshing state, so it will not drive the incomplete gear 45 to rotate. When the first gear 42 rotates for the third time, the first baffle plate 43 will touch the second baffle plate 44. The first baffle plate 43 makes the incomplete gear 45 and the first gear 42 The first gear 42 is meshed, and drives the incomplete gear 45 to rotate, and then returns to the meshed state so as to rotate together. When the incomplete gear 45 rotates, it drives the fixed column 46 to rotate. Since the fixed column 46 is fixedly connected to the eccentric center of the incomplete gear 45, when the fixed column 46 rotates, it drives the rotating rod 47 to deflect and move up and down. When the rotating rod 47 deflects and moves up and down, it drives the auxiliary slider 48 to slide in the slide plate 49. Through the coordinated use of the auxiliary mechanism 4 and the stirring mechanism 5, the intermittent transmission of the spacer of the stirring mechanism 5 by the auxiliary mechanism 4 is realized, and the reaction time of the lithium salt is effectively controlled, which is beneficial to the interaction and dissolution reaction between the solvent and the lithium salt, so that the lithium salt can be fully dissolved in the solvent. Full dissolution can ensure the uniform concentration of lithium ions in the solution, thereby improving the performance and stability of the battery. The control of the reaction time of the lithium salt can increase the number of interactions between the solvent and the lithium salt molecules, so that the solvent and the lithium salt are better mixed and evenly distributed, which helps to improve the uniformity of the solution, ensure the uniform distribution of lithium ions in the positive and negative electrode materials of the battery, and thus improve the performance and cycle life of the battery.

[0045] When the auxiliary slider 48 moves up and down, it drives the second cylinder 51 to move up and down. When the second cylinder 51 moves downward, it drives the second cylinder 54 to move downward. The through groove 53 is divided into a horizontal section and a vertical section. The second cylinder 54 drives the sliding column 55 to slide downward in the vertical section of the through groove 53. When the sliding column 55 slides to the bottom end of the vertical section, the second cylinder 51 drives the third cylinder 58 to move downward to extrude the inclined inner wall of the spiral groove 59. The third cylinder 58 causes the second cylinder 54 to rotate. When the second cylinder 54 rotates, it drives the sliding column 55 to slide in the horizontal section of the through groove 53. The second cylinder 54 rotates up and down and drives the stirring rod 56 to rotate up and down. The stirring rod 56 stirs the solvent and the lithium salt in the equipment housing 1. Through the coordinated use of the stirring mechanism 5, the solvent and the lithium salt in the dissolving equipment are rotated up and down and stirred. The up and down rotation and stirring can fully mix the solvent and the lithium salt, increase the contact area between the solvent and the solute, and accelerate the dissolution process. This helps the lithium salt to dissolve quickly in the solvent and improve the reaction efficiency.

[0046] The fourth cylinder 61 is composed of a round block and a long cylinder. A material port is provided in the first concave groove 64. In the initial state, the outlet of the through hole 62 located on the surface of the round block is in contact with the inner wall of the first concave groove 64. When the second cylinder 54 moves downward, the fourth cylinder 61 is driven downward. When the fourth cylinder 61 moves to contact with the fixed slide groove 63, the square slider 57 touches the fixed slide groove 63, causing the fourth cylinder 61 to deflect, so that the opening of the through hole 62 located on the surface of the round block is exposed in the material port. There is a cabin inside the second cylinder 54, so that the solvent and the lithium salt are poured into the cabin inside the second cylinder 54 through the through hole 62. Then the stirring stick 56 rotates the fourth cylinder 61 back and forth to leave the square slider 57. Since the fourth cylinder 61 is connected to the second cylinder 54 by a rubber rope, the fourth cylinder 61 is reset by the rubber rope after rotation, so that the opening of the through hole 62 on the surface of the round block fits with the inner wall of the first concave groove 64, and the solvent and lithium salt are stopped from being poured into the internal chamber of the second cylinder 54 through the through hole 62. When the internal chamber of the second cylinder 54 is filled with solvent and lithium salt, these liquids will generate pressure due to gravity, and this pressure will act on the circular plate 66. When the second cylinder 54 moves upward, the pressure of the liquid will increase, and the circular plate 66 is subjected to the pressure of the liquid, and the pressure pushes the circular plate 66 open, opening the second concave groove 65, and the liquid is discharged from the second cylinder 54 chamber. When the liquid is discharged, the pressure on the circular plate 66 disappears. Since the second concave groove 65 and the circular plate 66 are connected by a reset spring, the circular plate 66 is reset by the reset spring. Through the coordinated use of the spring plug mechanism 6, the solvent and the lithium salt at the bottom of the dissolving device are stirred. Through the coordinated use of the fourth cylinder 61 and the fixed slide 63, the through hole 62 is opened, so that the solvent and the lithium salt enter the second cylinder 54 chamber. When the circular plate 66 on the right moves upward, Since the solvent and the lithium salt are subjected to the action of gravity and generate pressure to push the circular plate 66 open, when the circular plate 66 is pushed open, the solvent and the lithium salt in the chamber of the second cylinder 54 flow out from the opening on the circular plate 66 to be discharged, thereby stirring the solvent and the lithium salt at the bottom of the dissolution equipment that are not easily stirred by the stirring mechanism 5, which can enhance the mixing effect of the bottom solvent and the lithium salt, and can also help break up the suspended clumps and enhance the intermolecular interaction between the solvent and the lithium salt, thereby promoting more complete mixing, and can reduce the temperature, concentration and composition differences between the bottom and the top of the solution, making the entire solution more uniform.
