The correct maintenance method of lithium battery automatic spot welding machine (1) Cooling aspect: Because when welding, you need to use cooling water, through this water to cool the electrodes, secondary circuits, transformers, thyristors, rectifiers and other power components, etc., to keep the battery automatic spot welding machine at a low temperature and can be used normally. Therefore, it is necessary to always check whether the various branch waterways are unblocked, and clear the blocked waterways in time. (2) For spot welding electrodes: The electrode is the part that directly acts on the workpiece during spot welding. It has good conductivity, hardness and high softening temperature, but it is still inevitably deformed under continuous high pressure impact and high temperature, so it needs to be based on the actual welding parameters, Correct the thickness and cleanliness of the electrode end in time for the number of solder joints, or directly replace the electrode in time. (3) The grounding wire should be connected well: In order to ensure the safety of the battery automatic spot welding machine, the ground wire must be used, and a good preservation is carried out through the ground wire. When connected to the ground, the resistance can be reduced, and the operation can be safer and used normally. (4) Cleaning of battery automatic spot welding machine: For the cleaning of the automatic battery spot welding machine, the body must ensure that the transformer and power components inside are clean. It is welded by electricity, and the safety of electricity must be ensured; the main board in the control box must be frequently dusted to avoid accumulation of metal dust Causes hidden dangers to the main board; the solenoid valve also needs to be cleaned and tested regularly, and the failure of the valve action will cause serious welding instability. Another part that needs to be cleaned frequently is the secondary copper connection part, especially the cleanliness of the surface of the part that is frequently disassembled and adjusted! Otherwise, the dirt and wear of the copper surface will increase the impedance of the secondary circuit and reduce the output of the welding current. Decrease the welding ability of the spot welder, and at the same time affect the stability of the welding current. (5) Inspection and calibration of welding controller: Especially for constant current controllers, it is necessary to regularly use authoritative third-party testing equipment to correct the welding current, otherwise the original welding current setting will cause poor welding due to current deviation. Only by insisting on maintaining the spot welding equipment for a long period of time, there will be no problems when welding, and the quality of spot welding can be guaranteed. ACEY provides one-stop solution for automatic single side spot welding machine, double sides spot welding machine and other machine of the battery pack assembly line.

As a portable energy storage device, lithium-ion batteries are widely used in mobile phones, notebook computers, cameras, electric bicycles, electric vehicles and other fields. Among them, the lithium battery electrolyte is an aspect that cannot be ignored. After all, the electrolyte, which accounts for 15% of battery cost, does play a vital role in battery energy density, power density, wide temperature applications, cycle life and safety performance. Electrolyte is one of the four key materials of lithium batteries: positive electrode, negative electrode, separator and electrolyte. It is called the "blood" of lithium ion batteries and conducts electrons between the positive and negative electrodes of the battery. It is to obtain high-voltage and high-voltage lithium batteries to ensure advantages such as energy ratio. As we all know, the main components of lithium-ion batteries include four aspects: positive electrode material, negative electrode material, electrolyte and separator. As an important part of lithium-ion batteries, electrolytes play an irreplaceable role in improving the cycle performance and energy density of lithium-ion batteries, thereby further increasing the range of electric vehicles. The energy density of lithium-ion batteries depends on the battery's voltage and capacity. In order to increase the energy density of the battery, in addition to increasing the capacity of the positive electrode material and the negative electrode material, another method is to increase the operating voltage of the battery. In this way, the battery will affect the electrolyte under high operating voltage. The high-pressure performance also puts forward new technical requirements. The electrolyte plays a role in conducting electrons between the positive and negative electrodes of the lithium battery, which guarantees that the lithium ion battery can obtain the advantages of high voltage and high specific energy. Electrolyte is generally prepared from raw materials such as high-purity organic solvents, electrolyte lithium salts, and necessary additives under certain conditions and in certain proportions. ACEY NEW ENERGY provides LiBOB electrolyte, LiFePO4 electrolyte, LiNiMnCoO2 electrolyte, LiPF6 electrolyte, NaPF6 electrolyte.

For lithium-ion batteries, the commonly used positive current collector is aluminum foil, and the negative current collector is copper foil. In order to ensure the stability of the current collector inside the battery, the purity of both is required to be above 98%. With the continuous development of lithium battery technology, whether it is lithium batteries used in digital products or batteries for electric vehicles, we all hope that the energy density of the battery is as high as possible, and the weight of the battery is getting lighter and lighter, and the most important thing in the current collector is Reduce the thickness and weight of the current collector to reduce the volume and weight of the battery intuitively. There are three reasons why lithium-ion batteries use aluminum foil for the positive electrode and copper foil for the negative electrode: First, copper and aluminum foil has good conductivity, soft texture and low price. We all know that the working principle of a lithium battery is an electrochemical device that converts chemical energy into electrical energy. In this process, we need a medium to transfer the electrical energy converted from chemical energy. Conductive materials are needed here. Among ordinary materials, metal materials are the most conductive materials. Among the metal materials, copper foil and aluminum foil are cheap and conductive. At the same time, in lithium batteries, we mainly have two processing methods: winding and lamination. Compared with winding, the pole pieces used to prepare the battery need to have a certain degree of flexibility to ensure that the pole pieces do not suffer from brittleness during winding. Among the metal materials, copper aluminum foil is also a softer metal. Finally, the cost of battery preparation is considered. Relatively speaking, the price of copper and aluminum foil is relatively cheap, and there are abundant copper and aluminum resources in the world. Second, copper and aluminum foil is relatively stable in the air. Aluminum is easy to chemically react with oxygen in the air, forming a dense oxide film on the aluminum surface layer to prevent further aluminum reaction, and this thin oxide film also has a certain protective effect on aluminum in the electrolyte. Copper itself is relatively stable in air, and basically does not react in dry air. The third is that the positive and negative potentials of lithium batteries determine the aluminum foil for the positive electrode and the copper foil for the negative electrode, not the other way around. The positive electrode potential is high, the copper foil is easily oxidized under high potential, and the oxidation potential of aluminum is high, and the surface of the aluminum foil has a dense oxide film, which also has a better protective effect on the internal aluminum. Both are used as current collectors because they have good electrical conductivity, soft texture (maybe it will also be good for bonding), and are relati...

As the main source of electricity in new energy vehicles, batteries provide power support for various systems, and their quality directly affects the normal driving of the vehicle. So how do we measure the quality of the battery? We can judge from the following aspects:    1. Appearance judgment Observe whether the appearance is deformed, bulging, leaking, ruptured, scorched, scorched, and whether there is oxide seepage at the screw connection, etc.   2. Battery testing equipment The fastest inspection method is to test the internal resistance and discharge current. A good quality battery has very small internal resistance and a large discharge current. Of course, there are also battery voltage drop (referring to the voltage difference when the battery is stored for a certain period of time in a static state), cycle life (referring to the number of times the battery is charged and discharged at a standard constant current and constant voltage), and battery platform time (referring to a certain cut-off voltage, The battery can discharge the total capacity of the amount of electricity), as well as resistance to high and low temperature discharge, large current overcurrent. To test the overall performance of a battery, a dedicated tester is necessary.   Xiamen Acey New Energy Technology Co., ltd, it is an industrial automation equipment manufacturer integrating product design and development, manufacturing, sales and engineering services.

Lithium-ion battery PACK is divided into four parts: processing, assembly, testing, and packaging. The battery PACK must be screened before. Different customers have completely different requirements for the cells before the lithium-ion battery PACK. Many manufacturers have a lot of battery PACK factories. Strict requirements, let’s take a look at the important process standards of lithium-ion battery PACK today. In the lithium-ion battery pack industry, people call batteries that are not assembled and can be directly used individually as batteries, and the finished battery pack connected to the PCM board with charging and discharging functions is called lithium-ion battery PACK. The PACK process of lithium-ion batteries refers to the assembly of battery cells, protective plates, battery wires, battery nickel sheets, battery accessories, battery boxes, battery membranes, etc. into finished batteries by welding. The battery pack PACK requires the battery to have a high degree of consistency (capacity, internal resistance, voltage, discharge curve, life). The vast majority of the existing lithium-ion battery PACK technology is to link the cells together by welding, which also complicates the maintenance of battery problems. In addition, the batteries may face many thorny problems when they are batched. Reliability of batch products, excellent battery PACK technology, and finished product testing are essential. 1. Full inspection standard of battery cell appearance The appearance standard of cylindrical batteries: no short circuit, oxidation, rust, leakage of veneer pad or skewed surface pad, film breakage, film wrinkle, etc. The appearance standard of the square battery cell: no electrolyte, burr or other contaminants on the surface, no leakage, bulging, deformation, short circuit, etc., no skew or warping of the surface pad, no oxidation, dirt, desoldering, etc. on the composite nickel belt. The appearance standard of polymer batteries: no electrolyte or other pollution on the surface, no leakage, swelling, deformation, etc., no fracture of the tab, no damage to the corners, no delamination, etc. 2. Standard for battery cell veneer pad The surface pad is required to be firmly pasted, not skewed, warped, not beyond the edge of the end face of the battery, and not cover the negative rivet---aluminum shell battery positive cap (for multiple parallel strings, use formed barley paper or red steel paper to paste)-- -For steel shell cylindrical batteries; covered with textured paper or high-temperature adhesive paper---polymer batteries. 3.

The power battery for electric vehicles is a lithium battery: the positive electrode is lithium iron phosphate (lithium cobalt oxide LiCoO2, or lithium manganese oxide LiMn2O4 or ternary compound Li(NiCo)O2) coated on aluminum foil, but lithium iron phosphate is the best . The negative electrode is copper foil coated with graphite or lithium titanate. There is a separator between the positive and negative foils, which are wound together. Put the wound positive and negative sheets (including the diaphragm) into the battery case together, inject the electrolyte, and then vacuum package to complete the production of a single battery. The procurement cost of lithium battery cathode materials accounted for 30%, anode materials accounted for 20%, separator materials accounted for 20%, electrolyte accounted for 20%, and casing accounted for 10%. The diaphragm is polyacrylic acid. The positive electrode material has a great influence on the battery performance (referring to the lithium compound coated on the aluminum foil), and the entire positive electrode is the most critical part of the battery. The development of the new energy automobile industry is not only related to national energy security, people's livelihood and environmental protection, but also involves the destiny of my country's automobile industry. The positive electrode of the lithium battery of electric vehicles needs aluminum foil, and the weight of the vehicle itself is required to be as light as possible. Aluminum is the preferred material for lightweighting of automotive parts. Aluminum plays a vital role in the development of electric vehicles and hybrid vehicles. It is predicted that China's electric vehicle ownership will account for more than 30% of the total in 2030. China's new energy automobile industry has opened up a new application field for the application of aluminum, with great potential and considerable consumption. The anode aluminum foil for lithium batteries has no special requirements on the performance of the aluminum foil, and the Chinese aluminum foil industry can fully meet all the requirements for this kind of foil.
