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. Flexible size, suitable for high rate batteries, shaped batteries, power batteries, etc.Each electrode size can be designed according to the battery size, so that the battery can be made into any shape.

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.

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.

The spot welding machine adopts the principle of double-sided double-point overcurrent welding. When working, the two electrodes press the workpiece to make the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and the welding current flows from one electrode to the other At the moment, the instantaneous thermal welding is formed at the two contact resistance points, and the welding current instantaneously flows from the other electrode along the two workpieces to this electrode to form a loop, and does not hurt the internal structure of the workpiece being welded. Scope of application: power battery 18650/26650/21700 battery cell serial-parallel combination, multi-parallel multi-string combination, power tool battery, twist car battery (1 mold spot welding 6 groups), energy storage battery pack, 18650 battery pack, 26650 battery pack, 32650 battery pack, electric bicycle battery, solar street light battery pack, ternary lithium battery, digital lithium battery, lithium iron phosphate battery, etc. Today, the custom double sides automatic welding machine has been shipped to our USA customer, used for welding large battery packs, this is the second time they purchased a spot welding machine from our company, we will provide you with reliable equipment and excellent after-sales service.
