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.

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. We, TOB New Energy ,we are not only provide the battery equipment , but also provide the battery technology.

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.

The manufacture of lithium-ion batteries is a process in which the process steps are closely linked. Overall, the production of lithium batteries includes the manufacturing process of the electrode, the battery assembly process, and the final electrolyte injection, battery case sealing, battery formation, and aging processes. In the three-stage process, each process can be divided into several key processes, each step will have a great impact on the final performance of the battery. The concept of formation is to charge and discharge a small current to the manufactured lithium ion battery. After the lithium battery is manufactured, it is necessary to charge and discharge the battery with a small current. there are mainly two purpose of pre-charging. After the battery is fabricated, the electrode material is not in the best applicable state, or the physical properties are not suitable (such as too large particles, the contact is not close, etc.), or the phase itself is wrong (such as some metal oxide anodes with alloy mechanism), requires first charge and discharge to activate. During the first charge of the lithium battery, Li + is released from the cathode active material, passes through the electrolyte-separator-electrolyte, and is inserted between the layers of the anode graphite material. We are TOB New Energy, we are not only provide the equipment of the battery,but also provide the knowledge of battery.
