During the operation of the coating machine, it will first follow two operation procedures:   1, the process of setting the thickness of the forward roller   2. Reversal roller coating process Coating machine reverse roll coating and its coating window: In the pole cloth machine, the slurry coating on the coating roll is the copper foil wrapped in the vacant area of the bright roll to the reverse roll. Or on aluminum foil. Therefore, the coating process must also meet the rules of reverse roller coating. In the reversal roll coating process, if the vacancy of the two rolls is relatively small, the capillary number is low enough, that is, when the viscosity or speed is relatively small, the activities in the plan with a relatively wide speed ratio are relatively stable. Can get better coating apparent quality. If the vacancy is relatively large, when the coating speed is high, it will simply show air entrapment, and there will be many fine air bubbles on the surface of the coating. Sometimes in order to increase the output value, the advancing coating speed is selected, which can show the harmfulness of air trapping. In order to eliminate this harmfulness, the operation method of reducing the space is selected. If the space is too small, the coating roller and the back roller are kneaded with each other, and the load of the motor and reducer is additionally added, which constitutes abnormal wear. This is also one of the reasons why the coating speed of the slurry in the reverse roller is limited. Forward roller coating and its coating window: First introduce the terminology in coating skills-coating window. Any coating method (method) has an applicable plan, which can be harmless within certain operating conditions (plan) Coating, that is, evenly coating a thin layer of fluid on the support, the plan of this coating operation is called the coating window in coating technology. In the coating machine, it is controlled by scheduling the metering gap between the two coating rollers and the metering roller that change in the same direction in the forward roller coating, and the coating of the required thickness is formed on the coating roller. The coating method is the special method of the rotating roller, that is, the speed of the metering roller is zero when the metering roller is not changed, and the cross-section of the metering roller is made into a comma shape, also called a comma scraper. The coating thickness can be adjusted by changing the interval between the comma blade and the coating roller. In this special method of forward roller coating, if the operation is improper, the position of the knife edge is contrary to the working direction, and the coating parameters and slurry parameters are not in a certain plan, it may present a vertical path harm, which is called a vertical path.

Many people have false welding during the welding process using the spot welder, but they cannot find a good solution. In fact, there are many reasons for the false welding. here are the introduce: 1. Stable power supply voltage: During the production process, the voltage of the power grid is unstable, and the high and the low determine the current size, resulting in false welding. 2. Dirt on the electrode surface: During the long-term welding of a large number of workpieces, a thick oxide layer will form on the surface of the electrode tip, which directly affects the conductivity and causes false welding and false welding. At this time, the electrode should be trimmed and removed. Surface oxide layer to achieve the ideal welding effect. 3. Setting of welding parameters: cylinder pressure, welding time, and current directly determine the welding quality. Only when these groups of parameters are adjusted to the best conditions can high-quality products be welded. The specific parameter settings are determined by the material, such as aluminum alloy plate, stainless steel plate, galvanized plate, nut and so on. There is a saying that we are all familiar with, called a good horse with a good saddle. The electrode is a saddle for the automatic spot welding machine, so in addition to choosing a good spot welding machine, we must also pay attention to choosing the appropriate electrode material, so that the spot welding machine can perform better and have a longer service life.  The electrode must transmit current, pressure and heat during the use of the automatic spot welding machine. According to this feature, our basic requirements for electrode materials are as follows: 1. High strength and hardness at high temperature, good resistance to deformation and wear; 2. High electrical conductivity and thermal conductivity, low self-resistance heating, can quickly eliminate the heat from the welding zone, extend the life of the electrode, and improve the heating state of the surface of the weldment of the automatic spot welding machine; 3. The tendency to form an alloy with the weldment metal at high temperature is small, the physical properties are stable, and it is not easy to bond.    One thing to note is that not all electrode materials for spot welding machines have to meet the above-mentioned requirements well, and appropriate electrode materials should be selected according to their own welding process and welding material characteristics. For example, welding high-temperature alloys requires the use of electrode materials with high hardness at high temperatures, but their electrical conductivity and thermal conductivity are often poor, and attention must be paid to cooling during welding. When welding aluminum and aluminum alloy metals with high electrical conductivity, electrode materials with low electrical conductivity, such as copper, cadmium copper, etc., should be selected, but they have high hardness at high temperatures and ...

1. Choose gloves suitable for different workplaces. The size of the glove should be appropriate. If the glove is too tight, it will restrict blood flow, which will easily cause fatigue and uncomfortable; if it is too loose, it will be inflexible to use, and it will easily fall off. 2. The selected gloves must have sufficient protective effect. For example, in the environment where steel wire cut-resistant gloves should be used, synthetic yarn cut-resistant gloves cannot be used. To ensure its protective function, it is necessary to change gloves regularly. If the expiration date is exceeded, hands or skin may be injured. 3. Check the gloves at any time to check whether there are small holes or damaged or abraded places, especially finger joints. For glove box gloves, the inflation method can be used for inspection. 4. Pay attention to the use occasions of gloves. If a pair of gloves are used in different places, the service life of the gloves may be greatly reduced. 5. Pay attention to safety during use, do not throw away contaminated gloves arbitrarily to avoid harm to others. Keep gloves that are not in use in a safe place. The above is the "Precautions for the Use of Laboratory Glove Box Gloves". Everyone must pay attention to these when using them in normal times, so as to ensure the accuracy of the experimental results. ACEY provides lab glove box, vacuum glove box, vacuum glove box with Purifying Function for lithium battery R&D.

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...
