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

  • Analysis and Summary of Lithium Battery Formation Process
    Analysis and Summary of Lithium Battery Formation Process May 15, 2020
    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.

    Tips when welding 18650 lithium ion battery pack May 06, 2020
    18650 lithium-ion battery is one of the most common lithium-ion batteries on the market today. Cylindrical batteries commonly used in battery PACK, that is, people often say 18650, 21700, 32650 and other specifications batteries. The 18650 lithium ion battery pack process is mainly based on the PACK battery structure. Most of the 18650 lithium battery pack process features are similar. TOB New Energy can supply the automatic 18650 battery pack double side spot welding machine for 18650,26650,32650 cylinder battery pack automatic spot welding, it can weld both side together with high speed and good effect. What should be paid attention to when welding 18650 lithium ion battery pack process? 1. Pay attention to the spot welding current when welding 18650 lithium ion battery. 2. Pay attention to the diameter of the welding pin when welding 18650 lithium ion battery. 3. When welding 18650 lithium-ion batteries, pay attention to the distance between the welding pins. 4. When welding 18650 lithium-ion battery pack process, pay attention to the number of welding points. 5. Can not explode fire, short circuit, or virtual welding during spot welding. Multi-parallel multi-series 18650 lithium ion battery pack design process skills 1. Adopt the principle of priority and easy operation, that is, employees are easy to operate. 2. Adopt the principle of priority operation safety, that is, employees are not easy to short-circuit or have better preventive measures during operation. 3. Adopt the principle of equipment, that is, use auxiliary equipment to complete as little as possible, and at least semi-automatic. 4. The packaging design should be reasonable, easy to take and put, and don't take the product out to the customer for a long time. There are many reasons for the inconsistency of the 18650 lithium-ion battery before PACK. The materials constituting the battery are not completely consistent, and the process of manufacturing the battery cannot be controlled to the same degree in every detail. This will lead to inconsistent capacity, inconsistent terminal voltage, inconsistent internal resistance, inconsistent life, etc. In addition to the electrical performance to be screened, the appearance of the 18650 lithium-ion battery should also be tested. For example, measuring defects such as scratches, breakages, stains, pits, bumps on the surface of the battery will affect the assembly of the battery module and the safety characteristics of the pack. We are TOB New Energy,we are not only provide the equipment of the battery,but also provide the knowledge of battery.
