A batch of vacuum oven for the cylindrical lithium battery production line has been completed. They will be sent to the customer's factory soon. Vacuum ovens are widely used in chemical, electronics, food, light industry, medicine, and other industries, and can dry materials under vacuum. It has the advantages of fast drying speed, low pollution and no damage to the internal quality of the dried items. The special vacuum oven for lithium batteries is a vacuum oven specially designed for the baking process of lithium-ion batteries. Its working principle: the boiling point decreases with the decrease of air pressure. The boiling point of water is significantly reduced under negative pressure. When the pressure drops to -0.089Mpa, the theoretical boiling point can be reduced to 45°C. In a negative pressure environment, moisture is easier to vaporize. After the special oven for lithium battery is heated for a period of time under normal pressure, the moisture in the battery or pole piece is converted into water vapor; after the moisture evaporates, vacuum can be used to extract the water vapor; nitrogen is filled to break the vacuum to maintain a dry environment. In the actual baking process, the above three steps are different according to different processes, and generally require multiple cycles.

  • Vacuum Drying Oven and Drying Process
    Vacuum Drying Oven and Drying Process Jul 08, 2020
    The vacuum drying is to put the materials to be dried in an enclosed space, use vacuum equipment to reduce the air pressure in the enclosed space to an atmospheric pressure, and at the same time continuously heat the materials. In this way, the water molecules in the material gradually diffuse to the surface of the material due to the effects of pressure difference and concentration difference. After obtaining sufficient kinetic energy on the surface of the material, the binding of the intermolecular attraction is gradually overcome, and it escapes into the vacuum chamber of low pressure and then passes The vacuum pump is discharged into the atmosphere. Vacuum drying processes: The first is the heat transfer process, the material absorbs heat through the heat source, heats up and vaporizes the internal moisture; Secondly, in the process of liquid mass transfer inside the material, the water inside the material moves to the surface in the form of liquid, and then vaporizes on the surface; Finally, during the gaseous mass transfer process of the moisture on the surface of the material, the water vapor vaporized on the surface of the material gradually escapes into the inside of the vacuum chamber and flows to the outside through the vacuum chamber. To complete the above heat and mass transfer process, temperature, pressure and concentration are the key control factors; Temperature: The temperature of the heat source should be significantly greater than the temperature of the material to meet the energy required for its own temperature increase and vaporization of moisture. The higher the temperature, the faster the drying. Concentration: The so-called concentration refers to the concentration of moisture in the material. The internal concentration of the material is higher than the surface concentration of the material. Under the action of capillary force and concentration difference, it migrates to the surface and eventually reduces the concentration of moisture. Pressure: The steam pressure on the surface of the material is higher than the partial pressure of steam in the drying oven, which is the core theory of vacuum drying. Vacuum drying thermodynamics mainly studies the relationship between the vaporization temperature of water, the saturated vapor pressure and the degree of vacuum. The theoretical basis can be Clapron. Clausius formula expression The vaporization temperature of water is positively correlated with saturated vapor pressure and negatively correlated with vacuum degree. The smaller the saturated vapor pressure, the lower the vaporization temperature of water. Similarly, the greater the vacuum degree, the lower the vaporization temperature of water. Therefore, it can be seen that water is easier to achieve low-temperature vaporization in a vacuum environment. When the temperature is maintained at a certain value, increasing the vacuum in the drying chamber can convert more moisture on the surface of the material into water v...

  • Ultrasonic Metal Welding Process in Lithium-ion Battery Manufacturing
    Ultrasonic Metal Welding Process in Lithium-ion Battery Manufacturing Jul 01, 2020
    As a key part in the manufacturing process of lithium batteries, the welding process is applied to the connection of multiple positions of lithium battery aluminum/copper anode and cathode current collectors, electrodes, and battery packaging. Any welding joint defects will significantly affect the performance of lithium batteries. consistency. Therefore, it is necessary to understand the ultrasonic welding process. The principle of ultrasonic welding In the ultrasonic welding process, the transducer converts high-frequency electrical signals into ultrasonic vibration signals. High-frequency vibration is transmitted to the surface of the metal to be welded through the welding tool head. The interface metal oxide film is broken under a certain pressure and the intense friction of ultrasonic vibration, clean interface metal contacts and under the combined action of friction and ultrasonic softening, further plastic flow and diffusion will gradually increase the connection area and eventually form a reliable connection. Effect of welding pressure on welding The strength of the welded joint increases with pressure and then decreases. Welding pressure will change the sliding resistance of the welding interface. A small welding pressure will cause a small sliding resistance of the interface, so that the energy generated by the friction is not enough to form an effective connection at the interface; too much welding pressure causes the tool head to be pressed down too deep, welding the interface Metals bite each other, which affects the relative motion of the interface, hinders the further connection of the interface metals, and results in poor mechanical properties of the welded joint. Therefore, proper welding pressure parameters are decisive for welding quality. Effect of time on welding The welding time directly affects the energy input during the welding process and has a direct effect on the welding effect. The welding time is too short and the input energy is insufficient. It is difficult to form an effective solder joint due to insufficient friction; as the welding time increases, the temperature increases due to mutual friction, the workpiece material begins to soften, and the oxide film at the interface of the welding area is damaged and plastically deformed , Can form a better connection; when the welding time is further extended, the welding head is easy to form deep marks on the surface of the workpiece, which will adversely affect the welding effect. In addition, too long welding time will easily cause the welding head and the workpiece to be welded Bonding Effect of amplitude on welding In the ultrasonic welding process, the vibration system formed by the workpiece and the workpiece directly affects the instantaneous velocity of the vibration at the interface of the workpiece, which ultimately affects the friction heat generation and plastic deformation, which affects the welding quality.

  • Five Containers of Pouch Cell Equipment to  Russia
    Five Containers of Pouch Cell Equipment to Russia Jun 19, 2020
    Today after a whole day hard work,we finally finished the five containers equipment for pouch cell pilot line to Russia. Good weather and good project. Pouch cell electrode making is same as other model electrode,it is mainly different at the assembly.From electrode stacking to sealing. Stacking After the production of the electrode, it is transferred to the stacking. The stacking means that the cathode, the separator, and the anode are stacked layer by layer to make a jolly roll. There are two main stacking methods, winding and zigzag stacking. Aluminum laminated film forming Punching, punching is a forming process for Aluminum laminated film. After feeding the aluminum-plastic film, the aluminum-plastic film is deformed through the punching die, and there is a pocket for us to store the core. Pre-sealing There are a total of four packages. The pre-package we mean refers to the top and side seals, leaving a seal to facilitate electrolyte injection. After placing the core in the pit, the entire aluminum-plastic film can be placed in the jig for top sealing and side sealing in the top side sealing machine. When encapsulating, the two heads have a certain temperature (generally around 180 ℃), and when pressed, they are pressed on the aluminum plastic film, and the PP layer of the aluminum plastic film melts and then sticks together. Second-sealing During the second seal, the air bag is punctured by a guillotine and a vacuum is drawn at the same time, so that the gas in the air bag and a small part of the electrolyte will be drawn out. Immediately afterwards, the two sealing heads are encapsulated in the second sealing area to ensure the airtightness of the cell. Finally, cut off the airbags after the packaged cells. After the second airbags are cut, you need to trim and fold the edges. That is, cut the one edge and the second edge to a suitable width, and then fold it to ensure the battery core. The width does not exceed the standard, such a soft-packed battery core is basically formed.

    After drifting on the sea for some days,our Brazil customer had received our equipment for pouch cell assembly. After a few times installment and debug they are really satisfied our equipment and finished the equipment acceptance.What a beautiful and tidy laboratory! There are two mainstream methods of making the cells of polymer battery, stacking and winding. Battery electrode stacking is through the equipment follow the Z-shape stack the anode and cathode electrode and battery separator together. Our customer adopted is this way. And another is use the winding needle to winding the cathode anode and separator to be a battery cell. Stacking process maybe need some more time, but here also have the advantage that people can not refuse: 1. Low internal resistance,equivalent to multiple small electrode in parallel, reducing internal resistance. 2. High rate discharge capacity,parallel connection of multi-electrode makes it easier to complete large current discharge in a short time. 3. High discharge platform,the internal resistance is lower and the polarization is smaller, so the discharge platform will be higher than the winding battery and closer to the material self-discharge platform. 4. High capacity density,the internal space of the battery is fully utilized, so compared with the winding process, the volume specific capacity is higher. 5. High energy density,the discharge platform and volume specific capacity are higher than the winding process battery, so the energy density is correspondingly higher. 6. Wide range of application,whether it is made into ultra-thin batteries or ultra-thick batteries, the lamination process can be competent. 7. Thickness is easy to control, not easy to deform,the internal structure of the battery cell is consistent, and the thickness of each part of the battery is correspondingly consistent, so it is easy to control its thickness. At the same time, the internal structure is unified, the reaction rate is relatively consistent, even if the thick cell is not easily deformed 8.
